What Is a Case Study?
When you’re performing research as part of your job or for a school assignment, you’ll probably come across case studies that help you to learn more about the topic at hand. But what is a case study and why are they helpful? Read on to learn all about case studies.
At face value, a case study is a deep dive into a topic. Case studies can be found in many fields, particularly across the social sciences and medicine. When you conduct a case study, you create a body of research based on an inquiry and related data from analysis of a group, individual or controlled research environment.
As a researcher, you can benefit from the analysis of case studies similar to inquiries you’re currently studying. Researchers often rely on case studies to answer questions that basic information and standard diagnostics cannot address.
Study a Pattern
One of the main objectives of a case study is to find a pattern that answers whatever the initial inquiry seeks to find. This might be a question about why college students are prone to certain eating habits or what mental health problems afflict house fire survivors. The researcher then collects data, either through observation or data research, and starts connecting the dots to find underlying behaviors or impacts of the sample group’s behavior.
During the study period, the researcher gathers evidence to back the observed patterns and future claims that’ll be derived from the data. Since case studies are usually presented in the professional environment, it’s not enough to simply have a theory and observational notes to back up a claim. Instead, the researcher must provide evidence to support the body of study and the resulting conclusions.
As the study progresses, the researcher develops a solid case to present to peers or a governing body. Case study presentation is important because it legitimizes the body of research and opens the findings to a broader analysis that may end up drawing a conclusion that’s more true to the data than what one or two researchers might establish. The presentation might be formal or casual, depending on the case study itself.
Once the body of research is established, it’s time to draw conclusions from the case study. As with all social sciences studies, conclusions from one researcher shouldn’t necessarily be taken as gospel, but they’re helpful for advancing the body of knowledge in a given field. For that purpose, they’re an invaluable way of gathering new material and presenting ideas that others in the field can learn from and expand upon.

You can find a wide range of solved case studies on myCBSEguide, covering various topics and concepts. Class 9 Science case studies are designed to help you understand the application of various concepts in real-life situations.
The rationale behind Science
Science is crucial for Class 9 students’ cognitive, emotional, and psychomotor development. It encourages curiosity, inventiveness, objectivity, and aesthetic sense.
In the upper primary stage, students should be given a variety of opportunities to engage with scientific processes such as observing, recording observations, drawing, tabulating, plotting graphs, and so on, whereas in the secondary stage, abstraction and quantitative reasoning should take a more prominent role in science teaching and learning. As a result, the concept of atoms and molecules as matter’s building units, as well as Newton’s law of gravitation, emerges.
Science is important because it allows Class 9 Science students to understand the world around us. It helps to find out how things work and to find solutions to problems at the Class 9 Science level. Science is also a source of enjoyment for many people. It can be a hobby, a career, or a source of intellectual stimulation.
Case study questions in Class 9 Science
The inclusion of case study questions in Class 9 science CBSE is a great way to engage students in critical thinking and problem-solving.

Case Study Questions Class 9 Science Matter in our Surroundings
Case study questions class 9 science chapter 1 matter in our surroundings.
CBSE Class 9 Case Study Questions Science Matter in our Surroundings. Important Case Study Questions for Class 9 Exam. Here we have arranged some Important Case Base Questions for students who are searching for Paragraph Based Questions Matter in our Surroundings.
At Case Study Questions there will given a Paragraph. In where some Questions will made on that respective Case Based Study. There will various types of marks will given 1 marks, 2 marks, 3 marks or 4 marks.
CBSE Case Study Questions Class 9 Science – Matter in our Surroundings
Case study 1:.
1.) A matter is anything that has mass and occupies space. Pen, paper, clips, sand, air, ice, etc. are different forms of matter. Every matter is made up of small particles. These particles are so tiny that they can’t be seen with naked eyes. Let’s see about the different characteristics of particles of matter.
- All matter is made up of very small particles.
- .Particles of matter has spaces between them.
- Particles of matter are continuously moving.
- Particles of matter attract each other.
Answer the following questions by referring above paragraph.
i.) Which of following is not matter?
c.) smell of perfume
d.) None of these
ii.) Thoughts coming in our mind are example of matter. True or false
c.) None of these
iii.) Which of the following is true about particles of matter?
a.) Particles of matter has spaces between them
b.) Particles of matter are continuously moving
c.) Particles of matter attract each other
d.) All of these
iv.) Give 5 examples of matter in our surroundings
v.) Enlist all properties of particles of matter
iv.) pen, pencil, notebook, ice and water
v.) Different characteristics of particles of matter are
Case Study 2:
2.) There are three states of matter – solid, liquid and gas.
Solids have a definite shape, distinct boundaries and fixed volumes, that is, have negligible compressibility. Solids have a tendency to maintain their shape when subjected to outside force. Solids may break under force but it is difficult to change their shape, so they are rigid.
Liquids have no fixed shape but have a fixed volume. They take up the shape of the container in which they are kept. Liquids flow and change shape, so they are not rigid but can be called fluid.
Gas as has indefinite shape, no fixed volume. Gas gets the shape and volume of container.
Gas has very low density hence are light. Gas can flow easily and hence are called fluid.
i.) Which of the following state of matter takes shape of container in which it is filled?
d.) Both b and c
ii.) Distance between particles of matter least in
iii.) Compressibility is least in case of
iv.) Give properties of solids.
v.) Give properties of Gases.
iv.) properties of solid are given below
- Solid has fixed volume.
- Solid has fixed shape.
- Solid has high density.
- Solids are heavy.
- Solid does not flow.
v.) Properties of gases are
- Gas has indefinite shape
- Gas has no fixed volume.
- Gas gets the shape and volume of container.
- Gas fills the container completely.
- Gas has very low density.
- Because of low density gas are light.
- Gas can flow easily and hence are called fluid.
Case Study 3:
3.) What happens inside the matter during change of state? On increasing the temperature of solids, the kinetic energy of the particles increases. Due to the increase in kinetic energy, the
Particles start vibrating with greater speed. The energy supplied by heat overcomes the forces of attraction between the particles. The particles leave their fixed positions and start moving more freely. A stage is reached when the solid melts and is converted to a liquid. The minimum temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.
The temperature of the system does not change after the melting point is reached, till all the ice melts. This happens even though we continue to heat the beaker, that is, we continue to supply heat. This heat gets used up in changing the state by overcoming the forces of attraction between the particles. The amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point is known as the latent heat of fusion. So, particles in water at 0 0 C (273 K) have more energy as compared to particles in ice at the same temperature.
The temperature at which a liquid starts boiling at the atmospheric pressure is known as its boiling point. Boiling is a bulk phenomenon. Particles from the bulk of the liquid gain enough energy to change into the vapour state. A change of state directly from solid to gas without changing into liquid state is called sublimation and the direct change of gas to solid without changing into liquid is called deposition.
i.) A change of state directly from solid to gas without changing into liquid state is called
c.) Boiling point
ii.) The direct change of gas to solid without changing into liquid is called
iii.) The energy supplied by heat to solid is used to overcome the forces of attraction between the particles. True or false
iv.) Define melting point and boiling point
v.) Define latent heat of fusion
iv.) The minimum temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point.
The temperature at which a liquid starts boiling at the atmospheric pressure is known as its boiling point.
v.) The amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point is known as the latent heat of fusion.
Case Study 4:
4 .) Do we always need to heat or change pressure for changing the state of matter? Can you quote some examples from everyday life where change of state from liquid to vapour takes place without the liquid reaching the boiling point? In the case of liquids, a small fraction of particles at the surface, having higher kinetic energy, is able to break away from the forces of attraction of other particles and gets converted into vapour. This phenomenon of change of a liquid into vapors at any temperature below its boiling point is called evaporation.
i.) Evaporation of liquid takes place at
a.) Boiling point
b.) Above boiling point
c.) Below boiling point
ii.) Evaporation takes place at surface of liquid because
a.) They are heavy as compare to other particles
b.) They have sufficient kinetic energy to break the force
c.) They are light weight as compare to other particles
iii.) During evaporation particles of liquid change into vapour
a.) From the surface
b.) From the bottom
c.) From all over the liquid
iv.) Define evaporation.
v.) Explain process of evaporation
iv.) The phenomenon of change of a liquid into vapors at any temperature below its boiling point is called evaporation.
v.) In the case of liquids, a small fraction of particles at the surface, having higher kinetic energy, is able to break away from the forces of attraction of other particles and gets converted into vapour. This phenomenon of change of a liquid into vapors at any temperature below its boiling point is called evaporation.
Case Study 5:
5.) You must have observed that the rate of evaporation increases with–
- an increase of surface area:
- We know that evaporation is a surface phenomenon. If the surface area is increased, the rate of evaporation increases. For example, while putting clothes for drying up we spread them out.
- an increase of temperature:
With the increase of temperature, more number of particles get enough kinetic energy to go into the vapour state.
In an open vessel, the liquid keeps on evaporating. The particles of liquid absorb energy from the surrounding to regain the energy lost during evaporation. This absorption of energy from the surroundings makes the surroundings cold. What happens when you pour some acetone (nail polish remover) on your palm? The particles gain energy from your palm or surroundings and evaporate causing the palm to feel cool. After a hot sunny day, people sprinkle water on the roof or open ground because the large latent heat of vaporization of water helps to cool the hot surface.
i.) Evaporation is surface phenomenon. True or false
ii.) As temperature increases the rate of evaporation is
c.) remains constant
iii.) The rate of evaporation increases with
a.) Increase in wind speed
b.) Decrease in wind speed
c.) Does not have any effect from wind speed
iv.) What happens when you pour some acetone (nail polish remover) on your palm?
v.) We are able to sip hot tea from saucer than from cup. Why?
iv.) The particles gain energy from your palm or surroundings and evaporate causing the palm to feel cool.
v.) We are able to sip hot tea from saucer than from cup. This is because saucer has large surface area, due to large surface area as compare to cut area tea evaporates at faster rate.
Thank you It helped me a lot
Why smell of Perfume is not a matter?
Because there is no particle
These all case study questions are really helpful . Thanks
This is my first I was so nervous but these questions help me alot thank you
Smell of perfume is a matter because it have gas particles means perfume particles
