Organization Of Life Presentation
Cells are the basic unit of life and were first discovered in 1665 by Robert Hooke using a microscope. The cell theory states that cells are the basic unit of life, all organisms are made of cells, and cells come from pre-existing cells. Cells group together to form tissues, tissues form organs, and organs work together in organ systems to carry out essential functions in the body. A living thing made of one or more cells is called an organism.
Levels of Organization (cell to organism)
This document discusses the levels of organization of living things from atoms to organisms. It begins by explaining that all matter is made of atoms which combine to form molecules and cells. Cells make up unicellular and multicellular organisms. Unicellular organisms consist of a single cell and can be prokaryotic or eukaryotic. Multicellular organisms are made of many eukaryotic cells that differentiate and organize into tissues and organs to carry out specific functions needed for organism survival.
Nervous system PPT for grade 10 (basic concepts regarding human nervous system)
Human nervous system is highly complex, while reading in higher classes, we often mix up concepts. In this SlideShare I've tried to simplify the material for grade 10 students to better understand the concept.
Cells Powerpoint Presentation
The document provides an overview of cells, including their history, structures, and differences between plant and animal cells. It explains that cells are the basic unit of life, first observed by Robert Hooke in 1660 when he looked at bark through a microscope and saw small compartments that he named "cells." The presentation then details the structures found in typical animal cells like the cell membrane, nucleus, mitochondria, and Golgi bodies. It concludes by noting additional structures like the cell wall, chloroplasts, and chlorophyll that are present in plant cells but not animal cells.
Biological levels of organization for Grade 7
The document discusses the levels of organization in biology from the smallest to largest. It begins with cells, which are the basic unit of life, and discusses tissues, organs, organ systems, organisms, populations, ecosystems, and finally the biosphere. Key characteristics of life are also defined, including being composed of cells, reproduction, growth and development, obtaining and using energy through metabolism, responding to the environment through homeostasis, having DNA as the universal genetic code, and evolving through adaptation.
Cell Biology Lesson Plan
This lesson plan aims to teach students about the cell membrane and cell wall. It will discuss their structures, compositions, functions and histories. Students will participate in activities like a cell structure scramble game and building models of the cell membrane and cell wall. The lesson emphasizes that the cell membrane is a thin, semi-permeable bilayer that surrounds and protects the cell, while the cell wall is a tough, outer layer found in plant cells made mostly of cellulose that provides structure and prevents bursting.
Levels of organization and charat of life rev
This document outlines the levels of biological organization from smallest to largest, including atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, biomes, and the biosphere. It then discusses the key characteristics of life, such as biological organization, acquiring materials and energy, reproduction, growth and development, homeostasis, response to stimuli, DNA as the genetic code, and evolution and adaptation.
Atomic structure presentation
Atoms are composed of electrons, protons, and neutrons. Electrons orbit around a small, dense nucleus composed of protons and neutrons. Over time, scientists have developed models of the atom based on new discoveries. Democritus first proposed atoms could not be further divided in 450 BC. In the 19th and 20th centuries, physicists discovered subatomic particles within atoms like electrons, proving atoms could still be divided. Now atoms are understood to have a nucleus surrounded by electron clouds.

Population density
This lesson plan explores population density through three activities. Students will learn about population, population density, and how physical geography influences where populations settle. In the first activity, students will label a map and learn how geography affects population density. The second activity uses dried beans to demonstrate the relationship between population size and area. Students scatter different numbers of beans in areas labeled Community A and B, then answer questions about which area has more people and appears more crowded. In the closing discussion, the teacher reviews key concepts and asks students where they would prefer to live, with more or fewer people.
Atomic structure.ppt 1
Atoms are composed of a nucleus containing protons and neutrons surrounded by an electron cloud. The nucleus contains positively charged protons and neutral neutrons. Negatively charged electrons reside outside the nucleus in the electron cloud. The number of protons defines the identity of an element and is equal to its atomic number. The total number of protons and neutrons is the mass number. The number of electrons equals the number of protons to maintain electroneutrality. Models such as the Bohr model depict electron arrangement in shells surrounding the nucleus.
Grade 7 - Cells, Functions of Organels
This document describes the structure and functions of various organelles found within cells. It explains that the cell membrane controls movement in and out of the cell, and that the cell wall supports and protects plant cells. The nucleus contains genetic material and is surrounded by the nuclear membrane. The endoplasmic reticulum helps transport proteins, with the smooth ER involved in fat synthesis and the rough ER containing ribosomes. Mitochondria produce energy and the Golgi apparatus packages proteins for transport. Lysosomes digest materials and vacuoles store reserves and control water levels. Chloroplasts are found in plant cells and are the site of photosynthesis.
Plant & animal cell
This document discusses plant and animal cells. It describes some of the key discoveries in cell biology including Hooke discovering cells in 1665 and von Leeuwenhoek first observing single-celled organisms under a microscope. The cell theory established that all living things are made of cells, cells are the basic unit of structure and function, and all cells come from preexisting cells. The document compares prokaryotic and eukaryotic cells and describes several organelles found in plant and animal cells including the nucleus, chloroplasts, mitochondria, endoplasmic reticulum, Golgi bodies and lysosomes. It notes both the similarities and differences between plant and animal cells.
Periodic table-families
The document discusses the different families of the periodic table. Elements are grouped into families based on their chemical properties. Each family has a specific name and elements within the same family react similarly with other elements. The families include alkali metals, alkaline earth metals, transition metals, boron family, carbon family, nitrogen family, oxygen family, halogens, noble gases, and rare earth metals. Each family is characterized by the number of electrons in the outer shell and whether the elements are metals, non-metals, or metalloids.
Module 2 atom inside out (grade 8)
J.J. Thomson discovered the electron in 1897 through his cathode ray experiment and proposed the "plum pudding" model of the atom in 1904. Later experiments provided evidence that atoms are made of even smaller subatomic particles. In the 1910s, Rutherford discovered the nucleus through his gold foil experiment and proposed a nuclear model of the atom. In 1932, Chadwick discovered the neutron through experiments bombarding beryllium with alpha particles. Atoms are now understood to have a small, dense nucleus containing protons and neutrons, surrounded by electrons in orbit.
Atomic theory
This document outlines the development of atomic theory from ancient Greek philosophers to modern physics. It describes key contributors such as Democritus, Dalton, Thomson, Rutherford, Bohr, and Schrodinger who proposed models of the atom based on experiments. The modern atomic theory is that atoms contain a nucleus of protons and neutrons surrounded by electrons in electron clouds, and that elements are defined by their atomic number while isotopes differ in neutron number. The four fundamental forces that act on atoms are also summarized.
Photosynthesis and Cellular Respiration
The document discusses photosynthesis and cellular respiration. It provides information on:
- The chemical equation for photosynthesis, which converts carbon dioxide and water into glucose and oxygen using sunlight.
- Cellular respiration, which breaks down glucose in mitochondria to release energy in cells.
- Photosynthesis and cellular respiration are interrelated processes - photosynthesis produces glucose that is used for energy in cellular respiration, and cellular respiration releases carbon dioxide and water used in photosynthesis.
Struture of an atom
This document provides an outline for a presentation on the history and structure of atoms. It begins with the early ideas of Democritus and Thomson, then describes the atomic models of Rutherford, Bohr, and others. The structure of the atom is explained, including the nucleus, protons, neutrons, and electrons. Isotopes and isobars are also introduced. The presentation would provide details on the key scientists and experiments that led to the current understanding of atoms as tiny particles consisting of a nucleus surrounded by electrons.

The highest level of organization is the biosphere, which includes all living and nonliving things on Earth.
PPT Biology G9 quarter1 lesson1 DNA in a Chromosome.pptx
This document provides information about genetics and DNA structure. It explains that DNA is packaged into chromosomes inside the nucleus of cells. DNA is made up of nucleotides that form genes, which determine traits. Genes are segments of DNA that code for specific proteins and physical characteristics. Chromosomes have two structures - loose chromatin and tightly coiled chromatids, with DNA wrapped around histone proteins in each structure.
CARBON COMPOUNDS SCIENCE 9
1. The document discusses several organic compounds including their molecular formulas, structures, and common uses. Carbon compounds like alkanes, alkenes and alkynes are discussed in terms of their bonding and properties.
2. Examples of uses mentioned include gasoline and ethanol as fuels, acetone as a solvent and in plastics/chemicals production, and formaldehyde as a building material and in household products.
3. The structures of hydrocarbons like alkanes, alkenes and alkynes are related to their bonding and properties, with saturated hydrocarbons containing only single bonds and unsaturated ones containing double or triple bonds.
Atoms, elements and compounds
This document provides an overview of atoms, elements, molecules, and compounds. It discusses how everything is made up of atoms, which contain subatomic particles like protons, neutrons, and electrons. Atoms of the same element have the same number of protons. Elements are organized in the periodic table according to their properties and atomic structure. Atoms can bond together to form molecules, which are made of one or more elements. Compounds are molecules made of two or more different elements bonded together. The properties of compounds are different from the individual elements.
Invertebrates
The document discusses various types of invertebrate animals. It describes their characteristics such as lacking backbones, having exoskeletons, tentacles, shells, legs or segments. Some examples provided include sponges, jellyfish, worms, snails, insects and arachnids such as spiders. Invertebrates make up 97% of the animal kingdom and live in a variety of environments on land and in water.
Invertebrates class ppt
Scientists classify animals into groups based on similarities to make the large number of species more organized. Vertebrates have backbones while invertebrates do not, and major invertebrate groups include jellyfish, flatworms, roundworms, segmented worms, mollusks, starfish, sea urchins, and arthropods such as crustaceans, insects, spiders, and centipedes/millipedes. Arthropods can be further divided based on traits like number of body segments, legs, and wings.
ISOTOPES_AND_ATOMIC_MASS.ppt
Isotopes are atoms of the same element that have different numbers of neutrons. The atomic mass of an element is an average value that takes into account the abundance of its isotopes. It is calculated using the relative abundance and mass of each isotope. For example, magnesium has three naturally occurring isotopes - 24Mg, 25Mg, and 26Mg. Calculating the weighted average of their relative abundances and masses gives the atomic mass of magnesium as 24.31 amu. Radioactive isotopes can be used for applications like carbon dating and medical diagnostics or treatment due to their ability to undergo radioactive decay.
Atoms and subatomic particles
This document discusses the structure of atoms and subatomic particles. It explains that atoms were once thought to be indivisible but are actually made up of subatomic particles, including electrons, protons, and neutrons. Each element is defined by its atomic number, or number of protons, while the mass number refers to the total number of protons and neutrons. Key subatomic particles are electrons, which have a negative charge; protons, which have a positive charge; and neutrons, which have no charge.

Atoms, Element, Molecule and Compound
This document defines and provides examples of atoms, elements, molecules, and compounds. It states that atoms are the basic unit of a chemical element and are made up of protons, neutrons, and electrons. An element is made of only one type of atom, while a molecule forms when two or more atoms bond together, whether of the same or different elements. A compound contains at least two different elements bonded together. It provides examples like water (H2O) as both a molecule and compound since it contains hydrogen and oxygen atoms bonded together.
Plant & animal cells
This document provides information about plant and animal cells. It defines cells and discusses their main purpose of organizing living things. It describes the parts of typical plant and animal cells and compares their structures. Plant cells have cell walls and chloroplasts, while animal cells lack these and can have flagella. The document also discusses how different types of animal cells, such as muscle, blood, skin, and nerve cells, are specialized to perform different functions in the body.
D) introduction to cells and tissues
All living organisms are made of cells and cell products. Cells vary in size, shape, and function. The basic unit of structure and function in the human body is the cell. Cells have a membrane, cytoplasm, and organelles that allow them to carry out functions. Tissues are groups of cells that work together to perform a specific function. The four main types of tissues are epithelial, connective, muscular and nervous tissue. Epithelial tissue covers and protects the body, connective tissue binds and supports other tissues, muscular tissue forms muscles, and nervous tissue transmits signals in the body.

Animal cell pp lesson
Here is a draft paragraph you could write as a cell:
As a cell, I am the basic unit of structure and function that makes up complex organisms. Cells come together to form tissues, which then make up organs. Groups of organs working together are called organ systems. There are two main types of organisms - unicellular organisms that are single cells, and multicellular organisms made of many cells like humans. I am produced through cell division, where my parent cell divides into two new daughter cells. My main structures include a cell membrane that encloses my cytoplasm, a nucleus that controls my functions, mitochondria that provide me energy, and a vacuole for storage. Together with other cells, I form the basic tissues, organs

Cells are the basic unit of all living things. They have organelles that perform specific functions to keep the cell alive. Plant and animal cells differ in structures like plant cells having a cell wall and chloroplasts. Organelles like the nucleus, mitochondria, chloroplasts, and ribosomes each have important roles in cellular functions and homeostasis. Cells come from other living cells according to the cell theory.
Cells and cell specialization
This document discusses cell structure and specialization. It defines cells as the basic unit of life and identifies their main parts as the nucleus, cytoplasm and cell membrane. The document explains that while all cells share these basic components, they come in many shapes and forms due to specialization. Specialized cells take on specific functions like transporting oxygen (red blood cells), movement (muscle cells), and defense (white blood cells). The adaptive features of different cell types allow organisms to carry out vital processes through systems of specialized cell types working together.
Cells
This document summarizes the organization of life from cells to organisms. It explains that cells are the basic unit of life, and can exist singly as in unicellular organisms or together in multicellular organisms. In complex organisms, cells combine to form tissues like muscle and epithelial tissues. Tissues then combine to form organs such as the heart and liver. Organs work together in organ systems, such as the circulatory or respiratory systems, and all the systems function as a whole to form a complex multicellular organism.
G7 ch3.1 levels of organization
This document discusses levels of biological organization from unicellular to multicellular organisms. It describes prokaryotes as unicellular organisms without nuclei and eukaryotes as unicellular organisms with nuclei and organelles. Multicellular organisms are made of many eukaryotic cells that differentiate and specialize in structure and function. Through cell differentiation, multicellular organisms develop from a single fertilized egg cell into diverse cell types organized into tissues, organs, and organ systems that work interdependently.
Celltheory 091102114019-phpapp01
Cells are the basic unit of structure and function of all living things. Robert Hooke first observed cells in 1665 under a microscope and named them due to their resemblance to rooms of monks. All cells come from preexisting cells and living things are made of one or more cells. There are two main types of cells - prokaryotic cells which lack nuclei and eukaryotic cells which have nuclei. Eukaryotic cells contain organelles that perform specific functions and plant and animal cells contain both similar and different organelles like chloroplasts in plant cells and lysosomes in animal cells.
Tissue
There are four main types of tissues in the human body and other animals: epithelial tissue, muscle tissue, nervous tissue, and connective tissue. Epithelial tissue covers the internal and external organs and has four types - squamous, stratified, cuboidal, and columnar epithelium. It provides barriers and allows for secretion and absorption. Muscle tissue includes skeletal, smooth, and cardiac muscle and enables movement through contraction. Connective tissue connects and supports organs and transports substances; its types include areolar, adipose, blood, lymph, bone, and cartilage. Nervous tissue is composed of neurons and transmits electrochemical signals. Plants also have tissues divided into meristematic and permanent tissue; meristematic tissue allows
Levels of Structural Complexity of the body.pptx
The document summarizes the levels of structural complexity in the human body from chemical to organismic levels. It begins with the chemical level consisting of atoms and molecules like proteins, carbohydrates, and water. The cellular level contains cells as the basic functional units. Tissues are made of groups of similar cells at the tissue level, including four main types. Organs are composed of at least two tissue types to perform specific functions. Systems consist of cooperating organs to perform common functions. Finally, the organismic level contains all systems functioning together to form a living being.

Cell.pptx
Cells are the basic unit of life. They range in size but all cells contain a nucleus and cytoplasm surrounded by a cell membrane. Within the cytoplasm are various organelles that carry out specific functions necessary for life. All organisms are made up of one or more cells that carry out functions like growth, transport of substances, and reproduction through cell division.
Bacteria, Animal and Plant Cells
The document provides information about the structure and function of cells. It discusses:
- The basic parts of prokaryotic and eukaryotic cells, including their genetic material, organelles, size, and whether they are unicellular or multicellular.
- The key structures of animal and plant cells, such as the cell membrane, nucleus, mitochondria, vacuoles, and in plant cells, the cell wall and chloroplasts.
- The functions of important organelles like the nucleus, which houses DNA; ribosomes, which produce proteins; and the endoplasmic reticulum and Golgi apparatus, which are involved in protein transport.
- Differences between animal and plant cells
Levels-of-organization (1).ppt
This document outlines the levels of biological organization from cells to the biosphere. It begins by describing unicellular and multicellular organisms and the differences between cells, tissues, organs, organ systems, and organisms. It then defines each level in more detail, from cells as the basic unit of life, to tissues as groups of the same cell type, organs as structures made of multiple tissue types, organ systems as groups of organs that work together, organisms as the whole entity, populations as groups of the same species, communities as multiple interacting populations, ecosystems as organisms and their environment, biomes as large climate-defined areas, and finally the biosphere as the portion of Earth that supports life.
Cell the structrural and functional unit of life
Cell is the basic structural and functional unit of life. All organisms start as a single cell that cannot be seen with the naked eye. The invention of microscopes allowed scientists to discover that cells are the smallest unit of structure and function, as stated in the Cell Theory. Cells come in various shapes and sizes depending on their function, and contain organelles that allow different metabolic processes to occur. All activities of living organisms result from cellular activities like growth, movement, feeding, and reproduction.
Life Science.Part2.Looking Inside Cells
1. The document discusses the structure and function of cells, from the organelles inside plant and animal cells like the nucleus, mitochondria, chloroplasts, to the differences between plant and animal cells.
2. It also covers the levels of organization in the human body from cells to tissues to organs to organ systems and examples like bone cells, bone tissue, and the skeletal system.
3. The highest levels of organization are organisms, which are individual living things, and ecosystems, which are communities of organisms that interact with each other and the environment.
level of organization (science biology) .ppt
Living things are organized at multiple levels, from cells to organ systems. Cells are the basic unit of life and make up tissues. Groups of tissues form organs, which carry out specific functions. Organs that work together as a unit comprise organ systems, which enable organisms to carry out life processes like digestion and respiration. This hierarchical structure progresses from the simple to the complex as the level of organization increases.

chapter-14.ppt
This document provides an introduction to fundamentals of electrochemistry, including:
1. Redox reactions involve the transfer of electrons between chemical species and can be monitored by measuring electric current.
2. A redox titration uses the transfer of electrons between analyte and titrant for analytical purposes. Reduction occurs when a substance gains electrons and oxidation occurs when a substance loses electrons.
3. Galvanic cells use spontaneous redox reactions to generate electricity by separating the half-cell reactions and allowing electrons to flow through an external circuit.
ch15.ppt
1) Thermodynamics is the branch of physics that deals with heat and work. The first law of thermodynamics states that the change in internal energy of a system equals the heat added to the system minus the work done by the system.
2) The second law of thermodynamics states that heat cannot spontaneously flow from a cooler body to a hotter body. All real-world processes are irreversible and cause the entropy of the universe to increase.
3) Heat engines use heat to perform work. The efficiency of heat engines is limited by the temperatures of the hot and cold reservoirs according to the Carnot efficiency formula. Refrigerators and heat pumps operate according to similar principles but use work to transfer
M3_Digestion Interaction with other Organ Systems.pptx
The document discusses the interactions between the digestive, circulatory, respiratory, and excretory systems. The digestive system breaks down food and absorbs nutrients into the bloodstream. The circulatory system then transports these nutrients and oxygen from the lungs to all the body's cells. The respiratory system supplies oxygen for cells to metabolize and the excretory system and respiratory system remove waste products from the body and cells. These systems are interdependent as the circulatory system connects them all and allows for the exchange of nutrients, oxygen, waste.
chapter31.ppt
This document discusses chemical equilibrium. It begins by explaining that many chemical reactions do not go to completion, but rather reach a state of dynamic equilibrium where the rates of the forward and reverse reactions are equal. This equilibrium state occurs when the concentrations of reactants and products remain constant over time.
It then introduces the equilibrium constant expression (K), which relates the concentrations or pressures of products and reactants at equilibrium. The value of K is unique to a particular chemical reaction at a given temperature. Examples are provided to demonstrate how K is calculated from experimental equilibrium concentrations. The summary concludes by noting that K can be expressed in terms of either molar concentrations (Kc) or partial pressures (Kp), and the relationship between these two expressions
chapter-14.ppt
1. The document discusses fundamentals of electrochemistry, including redox reactions, galvanic cells, and standard reduction potentials.
2. Key concepts covered include how redox reactions involve the transfer of electrons between oxidizing and reducing agents, and how this electron transfer can be harnessed to produce electric currents in batteries and cells.
3. The Nernst equation is introduced to calculate cell potentials under non-standard conditions when concentrations vary from standard values. This allows electrochemical cells to be used as probes of chemical equilibria.
WHAT MAKES THE earth's interior hot.pptx
The Earth's interior is hot due to two main sources of heat: primordial heat generated during Earth's formation from the condensation of gas and dust particles, and radioactive heat generated by the long-term radioactive decay of uranium, thorium, and other radioactive elements in Earth's core. These heat sources have not dissipated completely, accounting for about 10% of total heat still inside the Earth and causing volcanic eruptions at the surface.
ch12temp.pdf
This document discusses intermolecular forces and the physical properties of liquids and solids. It covers topics such as the different types of intermolecular forces, how these forces determine properties of liquids like viscosity and vapor pressure, crystal structure of solids, and phase changes between the different states of matter. The key points are that intermolecular forces are weaker than ionic or covalent bonds but still significantly impact properties, liquids and solids exist as a result of these intermolecular interactions, and phase changes occur with the addition or removal of heat to overcome these attractive forces.
Chapter-6-Colligative-Properties.ppt
This document discusses several colligative properties of solutions including boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure. It defines key terms like mole fraction, molality, and van't Hoff factor. It explains that in dilute solutions, molality and molarity are nearly equivalent. The document also covers conversions between solution properties, Raoult's law, and how dissociation of solutes is related to the van't Hoff factor and impacts freezing point depression and boiling point elevation.
Concentration of Solutions.pptx
The document provides information on different ways of expressing the concentration of solutions, including percent by mass, mole fraction, molarity, molality, percent by volume, and parts per million (ppm). It discusses an activity where students are asked to mix a substance with water and observe whether the mixture is uniform or non-uniform. Finally, it defines key terms related to solution concentration such as solution, solute, solvent, concentration, solubility, miscible, and immiscible.
Drrr2 - DISASTER IN DIFFERENT PERSPECTIVES.pptx
This document discusses different perspectives on disasters: physical, psychological, socio-cultural, and economic. It instructs readers to describe disasters from each perspective, how to deal with the disaster, and provide real-life examples of how disasters impact each perspective. It then provides prompts for a group activity involving discussing disasters from these different angles.
Biomolecules of life.pptx
This document discusses the key biomolecules that make up living things: carbohydrates, lipids, proteins, and nucleic acids. It explains that carbohydrates and lipids are made up of monomers and serve as energy sources, while proteins and nucleic acids are made of monomers and have a variety of functions including building muscles, strengthening the immune system, coding for traits, and catalyzing chemical reactions through enzymes. Enzymes are protein catalysts that speed up reactions and work best under certain pH and temperature conditions.
GROUP QUIZ.pptx
The document contains questions and answers about the electron configurations of various elements including calcium, chlorine, oxygen, bromine, and sodium. Specifically, it provides information on the number of electrons and neutrons in calcium, the electron configurations of chlorine and oxygen written in full and core notation, the number of valence electrons in oxygen and sodium, and the quantum numbers associated with the outer electron configurations of oxygen and sodium.
CHARLE'S LAW.ppt
Charles' Law states that the volume of a gas is directly proportional to its temperature when pressure is kept constant. It describes the observation that heating a gas causes its particles to move faster, collide with the container walls more frequently and forcefully, thereby increasing the gas's volume. The document provides an example problem demonstrating how to use the mathematical expression of Charles' Law to calculate a new temperature given an initial temperature, volume, and change in volume. It also explains Charles' Law at the molecular level, describing how increased particle speed and more forceful collisions due to higher temperatures cause gases to expand in volume.
BOYLE'S LAW.ppt
Boyle's law and Charles' law are both gas laws that describe the behavior of gases at different temperatures and pressures. Here are the key relationships:
- Boyle's law describes the inverse relationship between the pressure and volume of a gas at constant temperature - as pressure increases, volume decreases and vice versa.
- Charles' law describes the direct relationship between the volume and temperature of a gas at constant pressure - as temperature increases, volume increases and vice versa.
So in summary:
- Boyle's law examines how pressure and volume change at constant temperature.
- Charles' law examines how volume and temperature change at constant pressure.
They are related in that both laws look at how gas properties change when one variable is
M2_Lesson 1_Concept of Motion.pptx
1) The document discusses Aristotelian and Galilean views of motion, including vertical, horizontal, and projectile motion. It provides examples of free fall and projectiles.
2) Key figures discussed are Aristotle, who believed heavier objects fall faster, and Galileo, who argued that falling bodies experience constant acceleration regardless of weight through experiments.
3) The acceleration due to gravity near the Earth's surface is approximately 9.8 m/s2. Motion concepts laid by Aristotle and Galileo helped progress science, despite their opposing views.
M1_Lesson 1_How greeks know that earth is spherical.pptx
The Greeks knew the Earth was spherical based on several observations and arguments:
- Aristotle argued that a sphere is a perfect shape, and that pieces of Earth falling towards the center would form a round shape. He also noted that the Earth's shadow on the Moon in an eclipse is always circular.
- Navigation observations found that ships sailing away seemed to disappear behind the horizon, which wouldn't occur if the Earth was flat.
- Eratosthenes used recorded eclipse data to calculate the circumference of the Earth, providing evidence that it was spherical rather than flat.

2. It discusses Charles Darwin's contributions including his voyage on the HMS Beagle and publishing On the Origin of Species in 1859 introducing natural selection.
3. It provides examples of adaptations through structures like camouflage and mimicry as well as physiological adaptations in bacteria that provide evidence of evolution.
phy1.ppt
Sound waves are caused by vibrations that create regions of high and low pressure in air molecules. Longitudinal waves propagate through fluids by relying on pressure forces between molecules. The speed of sound depends on the elasticity of the medium - more elastic media allow sound to travel faster. Pitch is perceived as the frequency of a sound wave, while loudness depends on the amplitude. Timbre, which allows distinction between sounds of the same pitch and loudness, is influenced most by the harmonic content or overtones present in the sound waveform.
Thermodynamics - History.ppt
Carnot's idealized steam engine cycle showed that a heat engine cannot convert all heat into work and some heat must be rejected. This led to the second law of thermodynamics. Rudolf Clausius defined entropy as the "transformation content" of a body and introduced the concept that heat cannot spontaneously flow from cold to hot. Ludwig Boltzmann described entropy on a molecular level in terms of molecular kinetic energy. Josiah Willard Gibbs defined available energy, now called Gibbs free energy, as the maximum work obtainable from a system at constant temperature and pressure.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

PPT on Alternate Wetting and Drying presented at the three-day 'Training and Validation Workshop on Modules of Climate Smart Agriculture (CSA) Technologies in South Asia' workshop on April 22, 2024. JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
