2. what is energy
3. natural or artificial sources of light
4. luminous and non luminous objects
Class 6 chapter 4 Sorting materials into groups ppt 3
The document discusses the properties of different materials and an activity to observe these properties. It defines soluble and insoluble materials as those that do or do not mix with water. An activity is described where different substances are mixed with water to see if they are soluble or insoluble. Materials can also float or sink in water, with sugar, salt, and sand sinking and wax, oil, and wood floating. Transparency is also discussed, with transparent, translucent, and opaque materials defined based on how much can be seen through them.
Sorting materials into
This document discusses different properties that can be used to sort materials into groups, including appearance, hardness, solubility, and transparency. Appearance depends on whether a material has a lustre or not, hardness depends on how easily a material can be compressed or scratched, solubility depends on whether a material dissolves or remains intact in water, and transparency depends on whether light can pass through a material clearly, not clearly, or not at all. These properties can be used to categorize common materials like metals, paper, glass and determine if they are opaque, transparent, translucent, soft, hard, soluble or insoluble.
natural resources
The document summarizes natural resources and biogeochemical cycles. It discusses the main natural resources - air, water, soil, minerals and living organisms. It then focuses on the water cycle, carbon cycle, nitrogen cycle and oxygen cycle which are essential biogeochemical cycles. The greenhouse effect and ozone layer are also summarized as important atmospheric components that regulate climate and protect the earth.
Chapter - 9, Living Organisms And Their Surroundings, Science, Class 6
The document discusses different types of environments and habitats that organisms live in. It defines key terms like environment, biotic and abiotic components, and organisms. It then describes the characteristics of living organisms like nutrition, growth, respiration, excretion, habitat and adaptation. Specific examples are provided to illustrate how organisms like camels and fish are adapted to survive in their habitats like deserts and aquatic environments. The different terrestrial habitats of deserts, mountains, grasslands, rainforests and polar regions are outlined. Key aquatic habitats of oceans, rivers and lakes are also described.
CHANGES AROUND US (SCIENCE CLASS VI)
Let us now try and define change for the purpose of science. We can define it as an act by which a thing forms or becomes different than its previous self. For instance, when ice melts, it changes into water. Therefore it turns its form from solid to liquid.
Lights and shadows
The document discusses light and shadows. It defines light as a form of energy and light sources as objects that produce light. Light sources can be natural, like the sun, or artificial, like lamps. When a light source shines on an opaque object, it creates a shadow on the surface behind the object by blocking the light's path. Reflection occurs when light hits the surface of an object and bounces off in the same or different directions depending on whether the surface is smooth or rough.
Chapter 2 - is matter around us pure
Matter can be classified as pure substances or mixtures. Pure substances are either elements or compounds, while mixtures can be homogeneous or heterogeneous. Solutions are homogeneous mixtures where one substance dissolves evenly throughout another. There are several processes that can separate mixtures into their component substances, such as evaporation, crystallization, centrifugation, chromatography, and distillation. Physical changes alter the state of matter but do not change its chemical makeup, while chemical changes form new substances through chemical reactions.

Chapter 4 metals and non-metals (class-8) CBSE
Metals and non-metals are two types of elements. Metals are shiny, sonorous, ductile, malleable, and good conductors of heat and electricity, while non-metals are dull, non-sonorous, non-ductile, non-malleable, and poor conductors. Some exceptions are that mercury is the only metal in liquid form, sodium and potassium are soft metals, iodine is the only lustrous non-metal, and graphite conducts electricity unlike most non-metals. Metals react with oxygen to form metal oxides, hydroxides, and carbonates, while non-metals react with bases in a more complex process without hydrogen gas

Matter in our surrounding
Matter is composed of tiny particles that are constantly in motion. The properties and behavior of matter depend on the attraction and movement of these particles. Matter exists in three main states - solid, liquid, and gas - which are distinguished by how closely or loosely the particles are packed together and how freely they can move. A change in temperature can cause a substance to change states, such as melting from a solid to a liquid, boiling from a liquid to a gas, or condensing from a gas to a liquid.
microorganisms: friend and foe class 8(vishakha)
Microorganisms are tiny organisms that are present everywhere but cannot be seen with the naked eye. They include bacteria, fungi, algae, protozoa, and viruses. Some microorganisms are beneficial and are used to produce foods and medicines, while others can cause diseases. Proper sanitation, vaccination, and antibiotics can help prevent the spread of diseases caused by harmful microorganisms.

Class IV -States of Matter
There are three main states of matter: solids, liquids, and gases. Solids have a fixed shape and volume, liquids have a fixed volume but take the shape of their container, and gases fill their container evenly. Matter can change between these three states through processes like melting, freezing, evaporation, and condensation. When a solute dissolves in a solvent, it forms a solution, and soluble and insoluble substances can be separated from solutions through methods like filtration, sedimentation, and decantation.

Matter and forces .
Physical changes are changes that affect the form of a substance but not its chemical composition. Physical changes can be used to separate mixtures into their component compounds through processes like decanting, filtration, evaporation, and distillation. However, physical changes cannot usually separate compounds into chemical elements or simpler compounds.
Mixing and Separating
This document discusses various methods for separating mixtures, including:
- Crystallization to separate sugar from a soft drink by heating and evaporating water.
- Filtration to separate insoluble solids from liquids by passing the liquid through a filter.
- Distillation to separate liquids with different boiling points by evaporating and condensing them.
- Gravity separation to separate mixtures where components have different densities, like gold panning.
- Chromatography to separate colored substances in a mixture.
Matter in Our Surrounding Class 9 Science notes pdf
Class 9 Science introduces students to the fascinating realm of matter, the fundamental substance that makes up everything in the universe. In this article, we embark on a journey to understand matter, its various states, and its omnipresence in our surroundings.
I. Definition of Matter:
Matter is defined as anything that occupies space and has mass. It encompasses a vast range of substances, from the air we breathe to the solid ground beneath our feet.
II. States of Matter:
Matter exists in three primary states: solid, liquid, and gas. Each state exhibits distinct characteristics, and substances can transition between these states under varying conditions.
Solid: Solids have a fixed shape and volume. Examples include ice, wood, and metals.
Liquid: Liquids have a definite volume but take the shape of their container. Water, oil, and milk are common examples.
Gas: Gases have neither a fixed shape nor volume and fill the entire space available to them. Air and oxygen are examples of gases.
III. Changes of State:
Matter can undergo changes in its state through processes such as melting, freezing, evaporation, and condensation. For instance, water transitions from a solid (ice) to a liquid (water) when heated, and further to a gas (water vapor) upon reaching its boiling point.
IV. Importance of Understanding States of Matter
Understanding the states of matter is crucial in various scientific and practical applications. For example, knowledge of state changes is vital in the design of refrigeration systems, weather patterns, and industrial processes.
V. Brownian Motion:
The Brownian motion, discovered by Robert Brown, exemplifies the constant movement of particles in matter. It is visible when tiny particles, such as pollen, exhibit random motion when suspended in a fluid, revealing the dynamic nature of matter at the microscopic level.
VI. Diffusion:
Diffusion, another phenomenon related to matter, refers to the spontaneous movement of particles from regions of higher concentration to regions of lower concentration. An everyday example is the spreading of fragrance in a room.
VII. Sublimation:
Sublimation is the process by which a substance changes directly from a solid to a gas without passing through the liquid state. Dry ice (solid carbon dioxide) undergoing sublimation is a noteworthy example.
VIII. Applications in Daily Life:
Matter's significance extends to daily life, from cooking processes (water boiling) to the functioning of essential devices like refrigerators and air conditioners.

CBSE Class 9 Science Chapter-1 Matter in our surroundings
This document discusses the nature of matter and its different states. It begins by defining matter as anything that has mass and occupies space. It then describes the particulate nature of matter and how particles are in continuous motion and attract each other. The three common states of matter are identified as solids, liquids, and gases. A variety of experiments are presented to demonstrate the properties of each state, as well as how matter can change between states through processes like evaporation and condensation.
Presentation - Introduction to Physics and Chemistry
The document discusses the key concepts of matter and energy including the composition of matter as pure substances or mixtures, the different states of matter, types of changes matter undergoes (physical vs. chemical), and common forms of energy. It provides guidance for classroom activities where students will classify mixtures, demonstrate physical and chemical changes, and present on different forms of energy.
Presentation of science (matter)
Matter is anything that has mass and occupies space. It exists in three main states: solid, liquid, and gas. The state depends on how tightly or loosely the particles are packed. Solids have a fixed shape and volume as particles are tightly packed and vibrate in place. Liquids take the shape of their container but maintain a fixed volume as particles can move past one another. Gases have no definite shape or volume as particles are very far apart and move freely. Water can change states by adding or removing heat, going from solid ice to liquid to gas vapor.

HOW TO OBTAIN PURE COPPER SULPHATE FROM AN IMPURE SAMPLE
This document discusses crystallization as a technique for purifying substances. Crystallization involves dissolving an impure sample in a minimum amount of water, filtering out impurities, evaporating the water to form a saturated solution, then allowing crystals of the pure substance to form slowly as the solution cools at room temperature. As an example, impure copper sulfate can be purified through crystallization by dissolving it in water, filtering, evaporating the water to form crystals, which are then obtained in the china dish. Crystallization is widely used for purification in applications like sea water desalination, separating alum crystals, and in the pharmaceutical industry.

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.
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. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

- 3. - i. Oxygen gas is soluble in water. ii. Grouping things together with similar properties is called Sorting/Classification. iii. Mercury is the metal that exists in liquid state. iv. Potassium is a soft metal that can be cut with a knife. v. Iodine is a non-metal that has lustre. vi. A piece of stone is a hard material. vii. All gases are not soluble in water. viii. Dried leaf floats on the surface of water. ix. Oily patch on a piece of paper is translucent. x. Water is a transparent liquid. xi. Materials that have lustre are usually called as metal. xii.Materials are grouped on the basis of similarities or dissimilarities in their properties
- 4. GIVE ONE WORD FOR FOLLOWING 1. Will nail sink or float in water. Ans. Sink 2. Give one example of object having lusture? Ans. Gold 3. Name an opaque object? Ans. Wood 4. Give an example of transparent objects? Ans. Glass 5. The property of liquids to mix in all proportions, forming a homogeneous solution. Ans. Miscibility
- 5. SHORT ANSWERS Q1: Name three objects which can be made from wood? Ans.: chair , table and pencil. Q2: What is the difference between miscible and immiscible liquids? Ans.: Liquids that are soluble in water are called miscible liquids and the liquids that are not soluble in water are called immiscible liquid. Q3: write steps to make paper translucent. Ans. : Take a sheet of paper and look at the lighted bulb through it. spread a tea spoon of oil on one portion of paper. Now look at the lighted bulb through this patch. Now you will see bulb more clearly than before. This paper has now become translucent.
- 6. - Q4: Why do we need to classify things? Ans.: Since the materials are classified on the basis of similarities or differences in their properties. We group the materials to make our work easy. Q5: What is density? Ans.: Density is the mass per unit volume of the substance. Q6: What are lustrous materials? Ans. The materials which have natural shine on their surface or the shine appears when they are freshly cut or sand papered are called lustrous materials. Generally most of the metals are lustrous Q7: Why does a coin sink in water? Ans. Object with higher density than water will sink. A coin is made up of metal. Density of metal is higher than water. That’s why coin sinks in water.
- 7. -Q8: Why some material loses their shine and appears dull? Ans. Due to the action of air and moisture on them, a dull layer of some other compound appears on them. Thus material loses their shine and appears dull. Q9: Why does sugar dissolve in water? Ans. Water molecules surround the tiny sugar cubes and hit them. This weakens the attractive forces of the surrounding molecules and pulls them into the solution. Q10: Why water is considered as a universal solvent? Ans. Water is capable of dissolving most of the substances in it. That is why it is known as universal solvent. Q11. Define density. How is it related to floating and sinking in water? Ans. The degree of compactness of a substance is called density. The object which is denser than water will sink whereas object which is less dense than water will float.
- 8. LONG ANSWERS Q1. Define soluble substance, insoluble substance and solubility. Ans. The substance which dissolves in water is called soluble substance. Example – milk, ink, sugar, common salt etc. The substance which do not dissolves in water is called insoluble substance. Example – sand, stone, mud, glass etc. The property of substance due to which it dissolves in water is called solubility. Q2. Differentiate between transparent, translucent and opaque
