The skeletal system is made of bones and provides structure, support, and protection for the body. It allows for movement and protects delicate organs. Key bones include the skull, ribs, spine, shoulders, hips, and those in the arms, legs, hands, and feet. The skeleton is lightweight yet hard. During development, bones fuse together which is why babies have more bones than adults. Muscles are attached to bones and allow for movement by contracting and relaxing.

The skeletal and muscular system
The skeletal system document discusses the skeletal system and its functions. It provides information on important bones such as the skull, ribs, spine, and long bones. The skeletal system's main functions are support, protection of organs, muscle attachment, blood cell production, and mineral storage. Bones are made strong through calcium, vitamin D, and weight-bearing exercise. Joints allow movement and are held together by ligaments and cartilage. Muscles work with bones to create movement when stimulated. The three main types of muscle are skeletal, cardiac, and smooth muscle.
Skeletal System Ppt
The skeletal system is composed of 206 bones that provide structure, protect organs, allow movement, and produce blood cells. Bones are living tissues made of cells and composed of minerals and collagen. The skeletal system includes bones in the hands, face, and longest bone being the femur, with the smallest being the stirrup bone in the ear. Joints connect bones to enable the body's 230 movable joints, and giraffes have the same number of neck bones as humans.
Functions of internal organs
The document describes the main internal organs of the body, including the brain, heart, lungs, liver, stomach, kidneys, small intestine, and large intestine. It provides details on the location and functions of each organ, such as that the brain controls the body from the head, the heart pumps blood from the chest, the lungs help with breathing in the chest, the liver cleanses toxins from the blood, the stomach stores and breaks down food in the abdomen, the kidneys filter waste from the blood in the lower abdomen, the small intestine absorbs nutrients, and the large intestine releases waste products.
Muscular system
The document discusses the human muscular system. It notes that humans have over 600 muscles that are flexible and give strength, allowing for lifting, pulling and movement. Muscles are either involuntary, like those in the eyes, stomach and uterus which cannot be controlled, or voluntary like those in the face, arms and legs which are controlled by the brain sending messages to contract or relax. It then names and describes some major voluntary muscles like the biceps, quadriceps, abdominals, gluteus, pectorals and deltoids, and their functions. The document concludes by emphasizing the importance of daily exercise for keeping muscles healthy and strong.

The skeletal system has five main functions: providing structure and support, enabling movement, protecting organs, storing minerals, and forming blood cells. It is made up of the axial skeleton including the skull, spine, ribs, and sternum, and the appendicular skeleton of the shoulders, arms, hips and legs. Bones come in four basic shapes and have layers including compact bone, spongy bone, and bone marrow. The skeletal system includes over 200 bones and various joints like ball-and-socket, hinge, and pivot joints. Problems can include fractures, dislocations, arthritis, scoliosis and osteoporosis.
Skeletal System
The skeletal system is divided into two sections - the axial skeleton which includes the skull, vertebral column, and rib cage, and the appendicular skeleton which includes the limbs and girdles attaching them to the axial skeleton. Bones provide structure, protection, movement, mineral storage, and blood cell formation. There are 206 bones in the human body which come in four shapes - long, short, flat, and irregular. Bones are made of two types of tissue and contain three main cell types. Joints connect and allow movement between bones. The main types of joints are fibrous, cartilaginous, and synovial, with synovial joints providing the most movement.
The skeletal & muscular system
The document discusses the skeletal system and its key components:
- The skeleton is made up of bones and gives the body its shape while protecting vital organs. It also discusses how without a skeleton, the body would have no defined shape.
- It then discusses the main parts that make up the skeletal system including bones, cartilage, joints, ligaments and bone marrow. Bones come in different shapes and sizes and are made of calcium, while cartilage cushions joints and ligaments connect bones at joints.
- The document also mentions that there are three types of muscles in the body including smooth, cardiac and skeletal muscles which are attached to bones by tendons and allow for movement.
Skeletal System
The skeletal and muscular systems work together to help the body move. The skeletal system is made up of bones that support the body, give it shape, and protect organs. Muscles move the body by contracting and relaxing. There are three types of muscles - skeletal, smooth, and cardiac. Skeletal muscles move bones and allow voluntary movement. Smooth muscles line organs and blood vessels and work involuntarily. Cardiac muscle makes up the heart and contracts rhythmically without stopping.
Muscular System
The muscular system allows the body to move through muscle contraction and relaxation. There are approximately 600 muscles in the human body. Muscles are categorized as voluntary or involuntary. Voluntary muscles like those in the arms and legs can be consciously controlled, while involuntary muscles in organs cannot. The three main types of muscle are skeletal, smooth, and cardiac. Skeletal muscles move bones and are striated and voluntary. Smooth muscles are found in organs and are involuntary. Cardiac muscle is only located in the heart and is also involuntary. Muscles work in opposing pairs to enable movement, such as the biceps and triceps raising and lowering the arm.
Heart and Lungs
The heart and lungs work together to deliver oxygen throughout the body. The lungs bring oxygen into the body during inhalation and remove carbon dioxide during exhalation. The heart then pumps the oxygen-rich blood from the lungs throughout the body in a continuous cycle. Together, the heart and lungs form a tag team to supply the body with the oxygen it needs for biochemical reactions.
Human system
Our body contains many internal organs that work together in organ systems to carry out vital functions. There are two main types of organs - external organs that can be seen, and internal organs that cannot be seen and are protected by bones. The internal organs are grouped into organ systems like the circulatory, respiratory, and digestive systems to perform functions such as transporting blood, supplying oxygen, and breaking down food.
Skeletal System
The skeletal system has five main functions: movement, support, protection, blood cell production, and mineral storage. It is made up of bones and joints, with four basic bone shapes. The document describes the main bones in the skull, spine, shoulders, arms, hands, pelvis, legs, and feet. It also outlines the different joint types and connectors like ligaments and tendons. Common skeletal system problems are discussed like fractures, dislocations, sprains, arthritis, scoliosis, and osteoporosis.
Stomach and intestines
The document summarizes the structure and function of the stomach and intestines. The stomach breaks down food, stores it, and slowly empties into the small intestine. The small intestine further breaks down food with help from the pancreas, liver, and gallbladder. The large intestine absorbs water from undigested material and passes waste. Common ailments include indigestion, diarrhea, and constipation. Proper diet, hydration, chewing, eating habits, and bowel regularity help maintain stomach health.

3 pp twater cycle
The water cycle begins when water from bodies of water evaporates into water vapor due to heat from the sun. The water vapor condenses into water droplets in the air that form clouds. The water droplets in clouds join together and become too heavy, causing rain or snow to fall back to the ground. When rain falls on land, some water soaks into the soil and is used by plants, some becomes groundwater, excess water runs off into streams and rivers, and some evaporates back into the air to repeat the cycle.
3 ppt methods of separation
Filtration, magnets, evaporation, and distillation can be used to separate mixtures. Distillation involves separating liquids with different boiling points by evaporating and condensing them. The process of distillation separates liquids using evaporation and condensation.
2 ppt-suspension.
A suspension is a mixture where particles are mixed with but undissolved in a liquid and over time the particles settle to the bottom. Distillation is a process used to separate liquids with different boiling points by evaporating the mixture and then condensing the vapors to separate the liquids.
Respiratory system
The document describes the basic anatomy and function of the respiratory system. It lists the main organs - nose, trachea, lungs, and diaphragm. The respiratory system brings oxygen into the body through breathing and removes carbon dioxide, allowing oxygen to be delivered to the blood and carbon dioxide to be removed, while the diaphragm and lungs work together to enable breathing.
4 ppt states properties
This document discusses different states of matter and their properties. It defines solids, liquids, and gases based on their particle arrangement, attraction forces, and ability to change shape or volume. Key properties discussed include melting point, boiling point, freezing point, and density. Matter is defined as anything that has mass and takes up space. Mass is the amount of substance in an object, while volume refers to the space an object occupies. Density relates the distribution of mass within a given volume.

Electrical conductors allow electric current to flow through them, such as metals like copper and aluminum. Good electrical conductors are also generally good heat conductors. Electrical insulators do not allow electric current to flow through, such as plastics, wood, rubber and glass. A circuit tester can be used to determine if a material is a conductor or insulator by seeing if it allows a bulb in the circuit to light up when placed between the wires.
1 pp tmatter
Matter is anything that has mass and takes up space. There are three main states of matter: solids, liquids, and gases. Examples of the different states include ice as a solid, water as a liquid, and air as a gas.
Teeth
Teeth are used to break down food into pieces for swallowing. They come in different shapes for different functions - incisors cut, canines tear and hold, and molars grind and chew food. Humans have two sets of teeth - milk teeth that are replaced by 32 permanent adult teeth which will not regrow if lost. Teeth have layers including enamel, dentin, and a pulp chamber.
2 ppt changes in state
This document discusses the three states of matter - solid, liquid, and gas - using water as an example. It states that the solid state of water is ice, the liquid state is water, and the gas state is vapor. It also outlines the phase changes between the different states, such as melting and freezing between solid and liquid, and evaporation and condensation between liquid and gas.
Digestive system
The digestive system is a long tube running through the body that breaks down food into nutrients. Food enters the mouth where teeth grind it and saliva begins breaking it down before the tongue pushes it into the esophagus for swallowing. The stomach uses strong acids to further break down food while the liver and pancreas produce juices to digest it in the small intestine, where nutrients are absorbed and undigested waste moves to the large intestine to leave the body through the anus.
Classroom rules
We will discuss how to work together as a class respectfully. The most important rule is to respect oneself and others. This means valuing yourself, following rules, and not getting into trouble. As a student who respects themselves and others, the teacher will respect you in return. Some additional class rules include: raising your hand to speak, asking permission to drink or use the bathroom, bringing all supplies to class, and doing homework to earn full marks.
Nervous system
The nervous system is made up of the brain, spinal cord and nerves, which work together to control body organs, coordinate muscle movement, and interpret information from the senses. The brain and spinal cord form the central nervous system, which connects to nerves throughout the body to monitor and control organ functions and muscle activity based on sensory feedback.
Excretory system
The excretory or urinary system is responsible for producing liquid waste from the body in the form of urine. The kidneys remove waste from the blood using nephrons, which are tiny filters. The urine is then stored in the bladder and passes through the urethra when the bladder is full. The solid waste produced after eating is feces.
4 ppt reversible and irreversible change
The document discusses reversible and irreversible changes. Reversible changes can go forward or backward and do not result in new substances, such as folding paper or melting butter. Irreversible changes result in one or more new substances and cannot be undone, like burning wood or iron rusting. Examples are provided of both reversible changes like freezing orange juice and irreversible changes like burning a matchstick.
Lab tools
Safety goggles are used to protect eyes from flying objects or splashes. Common lab equipment includes beakers for heating and storing liquids, test tubes for holding hot or unused samples, pipettes for precise liquid measurement, balances for measuring mass, thermometers for temperature measurement, stopwatches for timing experiments, microscopes for magnifying small objects, and burners or hot plates for heating objects. Other equipment separates mixtures, measures length or volume, and determines direction.
Lab safety
The document outlines general lab safety rules for students, including not entering the lab without a teacher, following instructions, wearing protective clothing like lab coats, notifying the teacher of any spills or broken glass, tying back long hair and rolling up loose sleeves to avoid contact with chemicals, and never tasting chemicals or anything in the lab. Procedures for flushing chemical burns with cold water are also provided.
Presentation1 What is electricity
The document discusses the basics of static electricity and atoms. It explains that atoms are made up of positively and negatively charged particles that attract or repel depending on their charge. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or cloth to build up an excess of negative charges, which can then stick to walls or paper due to attraction between opposite charges. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.

Skeletal System PowerPoint.pptx
The skeletal system has five main functions: providing movement through muscle attachment points on bones, supporting the body, protecting organs, making blood cells, and storing minerals. It consists of two main parts - the axial skeleton including the skull and spine, and the appendicular skeleton including the shoulders, arms, hips and legs. Bones come in four basic shapes and have a layered structure of periosteum, compact bone, spongy bone, and bone marrow. Joints allow bones to move and come in both immovable and movable types, including ball-and-socket, hinge, pivot, and gliding joints.

Skeleton system
The skeleton provides 5 major functions: shape, support, body movement, protection, and blood cell formation. There are 4 types of bones: long, short, flat, and irregular. Joints allow movement and come in 4 types: ball and socket, hinge, pivot, and gliding. Ligaments connect bones, tendons connect muscles to bones, and cartilage protects joints. Synovial fluid reduces friction in joints. A healthy skeleton requires calcium, phosphorus, weight-bearing exercise, and avoidance of osteoporosis.
Lesson 1 skeletal system
This document provides an overview of lesson 1 on the skeletal system. It discusses the structure and functions of the skeletal system, including:
- The axial and appendicular skeleton and their components
- The five main functions of the skeleton: protection, support, movement, blood production, and mineral storage
- Bone growth and how cartilage is changed to bone through ossification
- Key bones such as the femur, humerus, ribs, and vertebrae that are involved in blood cell production
Human skeleton
The skeleton consists of bones and cartilage that work together to support the body, protect internal organs, and allow for movement. It has several key functions: providing shape to the body, supporting its weight, and shielding vital organs like the brain and senses. The skeleton contains many components, including different types of bones like those in the skull, ribs, and limbs, as well as cartilage in areas like joints.
Aaaaaa a skeletal system
The skeletal system has several key functions: providing points of attachment for muscles to facilitate movement, supporting the body, protecting internal organs, producing blood cells, and storing minerals. It consists of the axial skeleton including the skull, spine, ribs and sternum, and the appendicular skeleton including the shoulders, arms, hips and legs. Bones come in four basic shapes and have a layered structure consisting of periosteum, compact bone, spongy bone and bone marrow. Joints allow bones to move and come in both immovable and movable forms including ball-and-socket, hinge, pivot and gliding joints.
THE HUMAN BODY POWERPOINT
The document discusses the basic anatomy and structure of the human body. It describes that the body has 3 main parts: the head, torso, and limbs. It then discusses the skeleton system and how bones provide structure and support to the body. The skeleton is made up of bones, including the skull, spine, ribs, and others. Muscles are also discussed as working with bones to enable movement by contracting and relaxing. Key organs like the brain, heart, and lungs are also mentioned.

1. a&p skeletal 1
The skeleton has several key functions:
1) Movement - The bones and joints work with muscles to enable movement like walking, bending, and rotating.
2) Protection - The hard nature of bones protects delicate organs like the brain, heart, and lungs.
3) Support - Bones provide the framework that supports the body and allows it to stand upright.
4) Blood cell production - Bone marrow inside bones produces red and white blood cells.
5) Mineral storage - Bones act as a reservoir for minerals like calcium and phosphorus.

The document discusses bones and cartilage, the two materials that make up the human skeleton. It explains that cartilage is a strong, white material that bends, while bones are made hard by minerals. The document also names some parts of the body where cartilage is found, including the end of the nose, top of the ear, and where two or more bones meet. It then quizzes the reader on identifying bones, cartilage, or places with both in different body parts.
SCIENCE 4.BONES AND MUSCLES.pptx
The document discusses the skeletal system and the various bones that make up the human body. It provides details on the 206 bones in an adult body and 300 bones in a baby. Key bones mentioned include the skull/cranium that protects the brain, vertebrae that make up the spine and protect the spinal cord, ribs that shield the heart and lungs, pelvic bones that surround reproductive organs, and long leg bones like the femur. The skeletal system comprises all of the body's bones and allows for structure, protection and movement.
Muscular and skeletal systems: The Basics
The document discusses bones and muscles. It explains that bones have three main jobs: protection, muscle attachment, and support. Several key bones are then highlighted, including vertebrae, skull, leg bones, pelvis, and phalanges. For each bone, the reader is asked to identify the location and hypothesized function. The functions of bones are identified as protection, support, and muscle attachment. The document then discusses skeletal muscles and muscle fibers, explaining that muscles contract to pull bones and allow movement.
Importance of the skeletal system
The skeletal system serves four main purposes: 1) It gives the body its shape and structure. Without bones, the body would have no rigid framework. 2) It provides support and anchorage for muscles, organs, and soft tissues to keep them in their proper positions. 3) Bones protect vital internal organs like the brain, lungs, and heart. 4) The skeletal system allows for movement and locomotion through joints that respond to muscle contraction, permitting walking, running, grasping objects, and other motions.

Skeletal System
The skeletal system provides structure and protection to the body. It is made up of bones and cartilage that work together with muscles. The skeletal system has two main divisions - the axial skeleton which includes the skull, vertebrae, ribs, and sternum, and the appendicular skeleton which includes the bones of the shoulders, hips, arms, and legs. Bones come in different shapes and sizes and serve important functions like support, protection, movement, and storing minerals. The skeletal system is vital for overall health and well-being.
Chapeter 8: body movements
The document discusses locomotion and the skeletal and muscular systems that enable movement. It describes the three main types of joints - fixed, slightly movable, and freely movable - and provides examples like the ball and socket hip joint. The skeletal system is made up of bones and cartilage that protect organs and allow movement. Key bones include the skull, spine, ribs, limbs, and girdles. Muscles help movement by contracting and connecting to bones via tendons. Different animals like earthworms, snails, birds and fish have adapted skeletal/muscular systems suited to their environments and modes of locomotion.

Ch.10.acids and alkalis (3rd week)..
1) Acids and alkalis undergo a neutralization reaction where an acid reacts with an alkali to form a salt and water.
2) Common examples of neutralization include reactions between acids like hydrochloric acid, sulfuric acid, and nitric acid with alkalis like sodium hydroxide and potassium hydroxide.
3) Neutralization reactions have many applications including relieving insect stings, curing indigestion, baking cakes, putting out fires, and improving poor soil quality affected by acid rain.
Thermal energy
Thermal energy is the energy of moving particles that makes up heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. Temperature measures the amount of thermal energy in an object, with higher temperatures indicating more thermal energy. Thermometers measure temperature using liquids that expand when heated, allowing the user to read the temperature in degrees. Thermal conductors easily allow the transfer of heat, like metals, while insulators do not, like plastics and wood. Common materials are identified as conductors or insulators based on their ability to transfer thermal energy.
Ch.10.acids and alkalis (2).
Robert Boyle discovered that red cabbage juice and violets could be used as acid-base indicators. Red cabbage juice turns red in acids and green in alkalis, while violets turn purple in acids and greenish-yellow in alkalis. He also found that the juice from lichen (litmus) changed color between acids and alkalis and could be used on paper strips. This led to the development of the pH scale to quantify the strength of acids and alkalis from 0-14 based on their hydrogen ion concentration. Common pH indicators like methyl orange and phenolphthalein change color over different ranges on the pH scale to indicate whether a solution is acidic, basic, or neutral.
Ch.10. acids and alkalis (1).
This document discusses acids and alkalis. It notes that ancient Egyptians and Greeks observed that some substances taste sour while others feel slippery. Scientists later named sour substances "acids" and slippery substances "alkalis." Examples of acids found in nature include citric acid in oranges and lactic acid in muscles. Vinegar contains ethanoic acid. Acids can be classified as organic, produced by living things, or mineral. Common alkalis include sodium hydroxide, calcium hydroxide, and limewater. Concentrated solutions of acids and alkalis are corrosive, while dilute solutions are irritants. Alkalis are found in household cleaners and react with skin fat to produce soap-like substances.
Acids and alkalis 3
This document discusses neutralization reactions between acids and bases. It provides examples of common acids like hydrochloric, sulfuric, and nitric acid reacting with bases like sodium hydroxide and potassium hydroxide to form salts and water. Additional examples are given for using neutralization reactions to cure bee stings, treat indigestion, make baking powder rise in cakes, improve acidic soil for crop growth, and reduce the effects of acid rain by neutralizing it. The document also covers how neutralization can be used to clean teeth and dissolve mineral scales from kettles.
Acids and alkalis 2
Litmus is used to detect acids and alkalis. It can be used as a solution or absorbed into paper strips. Litmus solution turns red in acid and blue in alkali, while litmus paper turns red in acid and blue in alkali. The pH scale measures acidity and alkalinity from 0 to 14, with 0 being the strongest acid and 14 the strongest alkali. pH levels between 0-2 are strong acids, 3-6 are weak acids, 7 is neutral, 8-11 are weak alkalis, and 12-14 are strong alkalis.
Acids and alkalis 1
This document discusses acids and alkalis found in daily life. It notes that while some acids are corrosive, others like citric acid are found in foods and give them their sour taste. Examples of acids in living things include citric acid in oranges and lemons, ascorbic acid in fruits, lactic acid in muscles, and uric acid in urine. Vinegar contains ethanoic acid, also known as acetic acid, which is produced when oxygen reacts with ethanol in wine over time. Acids can be classified as organic acids produced by living things or mineral acids not produced by living things. While concentrated acids and alkalis are corrosive, dilute solutions are safer to handle.
Magnet 1
Magnets are made of iron, nickel, cobalt, or steel. To preserve a bar magnet, you should store it with another magnet pointing in the opposite direction to maintain its magnetic field. When a magnet breaks, its magnetic field also breaks into smaller magnetic fields. An electromagnet generates a magnetic field through a coil of wire when electric current passes through; placing an iron core in the coil makes the magnetic field stronger. Materials like iron, nickel, and cobalt are magnetic, while materials like aluminum, copper, glass, plastic, wood, and silver are non-magnetic.
Thermal energy ppt 1
Thermal energy is the energy of moving particles that causes heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. The document discusses conductors and insulators - materials that easily allow heat to pass through them are conductors like metals and materials that do not are insulators like rubber. It provides examples of common objects and whether they are thermal conductors or insulators.
Heat story
The saucepan was being stirred by a wooden spoon while heating gravy. The hood suggested using a metal spoon instead, but the wooden spoon argued it would not catch fire unless put in the gas flame. The saucepan, with a wooden handle, and kettle, with a plastic handle, agreed their materials keep the heat from reaching what they are holding. The window explained it does not let cold in but instead keeps the heat in the kitchen from escaping, which would result in it feeling cold without this function.
forces Presentation 2
Water exerts two main forces - upthrust force and water resistance. Upthrust force causes objects to float and is felt when holding down a floating object underwater. Water resistance is felt when walking or swimming through water, as water pushes back against movement. Air resistance also impacts moving objects, slowing them down depending on size, and can be useful for parachutes which use air resistance to slow falling.
forces Presentation 1
Forces cause objects to move, change direction, or stop moving. Unbalanced forces cause motion while balanced forces do not. Friction is a type of force that opposes motion between two surfaces and causes moving objects to slow down and stop. The more mass an object has, the greater its weight due to gravity.
Rock uses
This document discusses the uses of four different types of rocks: slate, granite, chalk, and marble. Slate is used for roofing tiles and billiard tables because it is hard, impermeable, and slips easily into thin sheets. Granite is used for steps, roads, buildings, and schools because it is hard and impermeable and doesn't wear away easily. Chalk is used for writing on blackboards because it is formed from sea creatures and wears away easily. Marble is used for floor and wall tiles and statues because it has attractive texture and color and can be cut and polished.
Types of soil
Soils are mixtures of bits of rocks, dead plants and animals, air and water that support plant growth. Different soil types like sand, silt and clay are distinguished by the size of their particles and how much air and water they hold. Sand drains easily while clay drains poorly, meaning different soil types support different plants.
Light energy
1. Light is a small part of the electromagnetic spectrum and can travel through a vacuum without a medium, unlike sound waves.
2. Light travels in transverse waves and when it hits objects can be absorbed, reflected, or pass through.
3. The major natural light source is the sun, while other sources can be natural or man-made. Objects like the moon and water reflect rather than generate light.
Types of soil
Soils are mixtures of bits of rocks, dead plants and animals, air and water that support plant growth. Different soil types contain particles of different sizes that impact drainage and which plants can grow best. Sand soil has large particles and drains easily while clay soil has tiny particles, few air gaps, and does not drain easily.
Minerals and rocks
The document discusses the three main types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form when magma or lava cools and hardens. Sedimentary rocks form through the compaction and cementation of sediments. Metamorphic rocks form when existing rocks are changed by heat, pressure, and chemical reactions deep underground. The rock cycle shows how the three rock types are interrelated as one rock type transforms into another over time.
Ch.11.less.1.how are forces and motion related?
1) The document discusses different types of motion including up and down, straight line, round and round, zigzag, and back and forth motion. It also discusses distance, direction, forces, and types of forces including balanced and unbalanced forces.
2) Forces can make something move, change an object's direction or speed, or change an object's shape. Examples of forces include gravity, friction, and air resistance.
3) Balanced forces do not change an object's motion, while unbalanced forces can make an object start or stop moving or change directions.
Light gb
Light comes primarily from the sun. It can also come from other natural sources like the moon or man-made sources like lamps. The moon and mirrors do not produce their own light but reflect light from other sources.
Light travels in straight lines and can pass through transparent materials, pass through translucent materials partially, or be blocked by opaque materials. The way light interacts with objects determines whether they appear colored or form shadows. Reflection and refraction explain how light bends when moving between different materials like air and water.
Ch.12.less.2.what are the properties of sound [autosaved] [recovered]
The document discusses key properties of sound including that it is a type of energy that moves through matter as longitudinal waves of vibrations called sound waves. It moves through three parts of the ear - outer, middle, and inner - and can be reflected as echoes. The pitch and frequency of sounds are related, though pitch is how our ears perceive it, and volume refers to the density of compressions and rarefactions in the air. Materials like wall padding and foam can absorb sound waves to reduce echoes and noise.

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
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.
Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.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.

- 7. What is the skeletal system made of? Bones
- 8. Function of the skeleton 1) Provide a framework for our body. 2) Support our body 3) Allow us to move 4) protects the organs inside our body
- 9. Skull protects the brain
- 10. Ribs protect the heart and lungs
- 11. Vertebral column protects the ( spinal cord )
- 12. Vertebral column supports the skull
- 13. Vertebral column helps us to stand straight and sit straight
- 14. Why the skeletal system protects some parts of our body? Because these parts are delicate and important
- 15. Periosteum – spongy bone – compact bone – bone marrow cavity – bone marrow
- 16. Spongy bone Compact bone Periosteum Bone marrow Bone marrow cavity
- 17. Look at the parts of the animal skeleton and compare it with the human skeleton
- 19. Which animal has ribs that are difficult to see ? Turtle How is the skeleton of the bird different from other skeleton ? It has wings Look at the other animals skeleton and compare it with the human skeleton
- 20. How many bones does a baby have? 300
- 21. How many bones does an adult have? 206
- 22. Where does the 94 bones go? It fuses together
- 23. X - ray
- 24. What do we call when a bone is broken? Bone fracture
- 25. 1- Greenstick fracture Types of bone fracture When the bone cracks in one side only
- 26. 1- Greenstick fracture Types of bone fracture When the bone cracks in one side only
- 27. 2- Clean break Types of bone fracture When the bone has broken into two bones
- 28. H.W – students bring x- ray
- 29. How does the bones move? What is attached to our bones ? muscles
- 32. Bend and stretch your left arm, feel the muscle with your right hand
