- Class 10 Science Case Study question examples
- How to get case-based questions for free?
- How to attempt the case-based questions in Science?
Questions based on case studies are some real-life examples. The questions are asked based on a given paragraph i.e. Case Study. Usually, 4-5 questions are asked on the basis of the given passage. In most cases, these are either MCQs or assertion & reason type questions. Let’s take an example to understand. There is one paragraph on how nitrogen is generated in the atmosphere. On the basis of this paragraph, the board asks a few objective-type questions. In other words, it is very similar to the unseen passages given in language papers. But the real cases may be different. So, read this article till the end to understand it thoroughly.
What is CBE?
CBSE stands for competency-based education. The case study questions are part of this CBE. The purpose of CBE is to demonstrate the learning outcomes and attain proficiency in particular competencies.
Questions on Real-life Situations
As discussed the case study questions are based on real-life situations. Especially for grade 10 science, it is very essential to have the practical knowledge to solve such questions. Here on the myCBSEguide app, we have given many such case study paragraphs that are directly related to real-life implications of the knowledge.
Sample Papers with Case Study Questions
Class 10 Science Sample Papers with case study questions are available in the myCBSEguide App . There are 4 such questions (Q.No.17 to 20) in the CBSE model question paper. If you analyze the format, you will find that the MCQs are very easy to answer. So, we suggest you, read the given paragraph carefully and then start answering the questions. In some cases, you will find that the question is not asked directly from the passage but is based on the concept that is discussed there. That’s why it is very much important to understand the background of the case study paragraph.
CBSE Case Study Sample Papers
You can download CBSE case study sample papers from the myCBSEguide App or Student Dashboard. Here is the direct link to access it.
Case Study Question Bank
As we mentioned that case study questions are coming in your exams for the last few years. You can get them in all previous year question papers issued by CBSE for class 1o Science. Here is the direct link to get them too.
Class 10 Science Case Study Question Examples
As you have already gone through the four questions provided in the CBSE model question paper , we are proving you with other examples of the case-based questions in the CBSE class 10 Science. If you wish to get similar questions, you can download the myCBSEguide App and access the Sample question papers with case study-type questions.
Case-based Question -1
Read the following and answer any four questions: Salt of a strong acid and strong base is neutral with a pH value of 7. NaCl common salt is formed by a combination of hydrochloride and sodium hydroxide solution. This is the salt that is used in food. Some salt is called rock salt bed of rack salt was formed when seas of bygone ages dried up. The common salt thus obtained is an important raw material for various materials of daily use, such as sodium hydroxide, baking soda, washing soda, and bleaching powder.
- Phosphoric acid
- Carbonic acid
- Hydrochloric acid
- Sulphuric acid
- Blue vitriol
- Washing soda
- Baking soda
- Bleaching powder
Case-based Question -2
- V 1 + V 2 + V 3
- V 1 – V 2 +V 2
- None of these
- same at every point of the circuit
- different at every point of the circuit
- can not be determined
- 20 3 Ω 203Ω
- 15 2 Ω 152Ω
Case-based Question -3
- pure strips
- impure copper
- refined copper
- none of these
- insoluble impurities
- soluble impurities
- impure metal
- bottom of cathode
- bottom of anode
How to Attempt the Case-Based Questions in Science?
Before answering this question, let’s read the text given in question number 17 of the CBSE Model Question Paper.
All living cells require energy for various activities. This energy is available by the breakdown of simple carbohydrates either using oxygen or without using oxygen.
See, there are only two sentences and CBSE is asking you 5 questions based on these two sentences. Now let’s check the first questions given there.
Energy in the case of higher plants and animals is obtained by a) Breathing b) Tissue respiration c) Organ respiration d) Digestion of food
Now let us know if you can relate the question to the paragraph directly. The two sentences are about energy and how it is obtained. But neither the question nor the options have any similar text in the paragraph.
So the conclusion is, in most cases, you will not get direct answers from the passage. You will get only an idea about the concept. If you know it, you can answer it but reading the paragraph even 100 times is not going to help you.

Magnetic Effects of Electric Current Case Study Questions With answers
Here, we have provided case-based/passage-based questions for Class 10 Science Chapter 13 Magnetic Effects of Electric Current
Case Study/Passage Based Questions
Question 1:
An electric motor is a rotating device that converts electrical energy into mechanical energy electric motors are used as an important component in electric fans, refrigerators, mixer, washing machines, computers, MP3 players etc. Motor Works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on the coil which rotates it continuously. When the coil rotates the shaft attached to it also rotates. In this way the electrical energy supplied to the motor is converted into the mechanical energy of rotation.
1.1) When the current is switched on, an electric fan converts : (a) electrical energy into mechanical energy (b) chemical energy into mechanical energy (c) electrical energy into mechanical energy (d) mechanical energy into electrical energy
Answer: (c) electrical energy into mechanical energy
1.2) In an electric motor, the direction of current in the coil changes once in each (a) two rotations (b) one rotation (c) half rotation (d) one-fourth rotation
Answer: (c) half rotation
1.3) An electron beam enters a magnetic field at right angles to it. The direction of force acting on the electron beam will be : (a) to the right (b) to the left (c) into the page (d) out of the page
Answer: (c) into the page
1.4) A magnetic field exerts no force on : (a) an unmagnetised iron bar (b) a stationary electric charge (c) a magnet (d) an electric charge moving perpendicular to its direction
Answer: (b) a stationary electric charge
1.5) Which of the following has no effect on the size of the turning effect on the coil of an electric motor? (a) The amount of the current in the coil. (b) The number of turns in the coil. (c) The direction of the current in the coil. (d) The strength of the magnetic field.
Answer: (c) The direction of the current in the coil
Question 2:
An insulated copper wire wound on a cylindrical cardboard tube such that its length is greater than its diameter is called a solenoid. When an electric current is passed through the solenoid, it produces a magnetic field around it. The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet. The field lines inside the solenoid are in the form of parallel straight lines. The strong magnetic field produced inside a current-carrying solenoid can be used to magnetize a piece of a magnetic material like soft iron when placed inside the solenoid. The strength of the magnetic field produced by a current-carrying solenoid is directly proportional to the number of turns and strength of the current in the solenoid.
(i) The strength of magnetic field inside a long current-carrying straight solenoid is (a) more at the ends than at the centre (b) minimum in the middle (c) same at all points (d) found to increase from one end to the other.
Answer: (c) same at all points
(ii) The north-south polarities of an electromagnet can be found easily by using
(a) Fleming’s right-hand rule | (b) Fleming’s left-hand rule |
(c) Clock face rule | (d) Left-hand thumb rule |
Answer: (c) Clock face rule
(iii) For a current in a long straight solenoid N-and S-poles are created at the two ends. Among the following statements, the incorrect statement is (a) The field lines inside the solenoid are in the form of straight lines which indicates that the magnetic field is the same at all points inside the solenoid. (b) The strong magnetic field produced inside the solenoid can be used to magnetise a piece of magnetic material like soft iron, when placed inside the coil. (c) The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet. (d) The N- and S-poles exchange position when the direction of current through the solenoid is reversed.
Answer: (c) The pattern of the magnetic field associated with the solenoid is different from the pattern of the magnetic field around a bar magnet.
(iv) A long solenoid carrying a current produces a magnetic field B along its axis. If the current is double and the number of turns per cm is halved, then new value of magnetic field is
(a) B | (b) 2B | (c) 4B | (d) B/2 |
Answer: (a) B

Here we have arranged some Important Case Base Questions for students who are searching for Paragraph Based Questions Magnetic Effects of Electric Current.
CBSE Case Study Questions Class 10 Science Magnetic Effects of Electric Current
Case Study – 1
Answer- It states that if we stretch thumb, forefinger or the index finger and the middle finger in such a way that they are mutually perpendicular to each other then the thumb gives the direction of the motion or the force acting on conductor, index finger gives the direction of magnetic field and the middle finger gives the direction of current.
State your observation in the galvanometer.
Explanation- Electromagnetic induction is a process by changing a magnetic field in a conductor, which induces a current in another conductor placed in nearby.
Case study: 4
If we stretched the thumb, forefinger and middle finger of our left hand so that they are mutually perpendicular to each other. If the forefinger gives the direction of magnetic field and middle finger gives the direction of electric current then the thumb gives the direction of motion or the force acting on the conductor.
The domestic electric circuit consist of red insulated cover called as live wire, wire with black insulation called as neutral wire and the wire with green insulation is called as Earth wire. We know that fuse is connected in series with the circuit to prevent the damaging of electrical appliances and circuit from overloading. Overloading occurs when live wire and the neutral wire comes in direct contact with each other. Because of which current through the circuit increases suddenly. Also, overloading may occurs because of connecting many appliances to a single socket. The Earth wire which is green in colour is connected to a metal plate deep in the earth near the house. This type of safety measure is used in appliances like electric press, toaster, table fan, refrigerator etc. The Earth wire is gives low resistance conducting path for the electric current. In this way it protects us from severe electric shock.
4) What is the main purpose of using fuse in electric circuit?
4) Because of Joule’s heating effect the heat produced causes the fuse to melt and to break the circuit. And thereby protect the circuit and electric appliances.

Case Study Chapter 10 Light Reflection and Refraction
Here, we have provided case-based/passage-based questions for Class 10 Science Chapter 10 Light Reflection and Refraction
Case Study/Passage-Based Questions
Question 1:
The spherical mirror forms different types of images when the object is placed at different locations. When the image is formed on the screen, the image is real and when the image does not form on-screen, the image is virtual. When the two reflected rays meet actually, the image is real and when they appear to meet, the image is virtual. A concave mirror always forms a real and inverted image for different positions of the object. But if the object is placed between the focus and pole, the image formed is virtual and erect. A convex mirror always forms a virtual, erect, and diminished image. A concave mirror is used as a doctor’s head mirror to focus light on body parts like eyes, ears, nose, etc., to be examined because it can form erect and magnified images of the object. The convex mirror is used as a rear view mirror in automobiles because it can form a small and erect image of an object.
(i) When an object is placed at the center of curvature of a concave mirror, the image formed is
(a) larger than the object | (b) smaller than the object |
(c) same size as that of the object | (d) highly enlarged. |
Answer: (c) same size as that of the object
(ii) No matter how far you stand from a mirror, your image appears erect. The mirror is likely to be
(a) plane | (b) concave |
(c) convex | (d) either plane or convex. |
Answer: (d): The image is erect in a plane mirror and also in a convex mirror, for all positions of the object.
(iii) A child is standing in front of a magic mirror. She finds the image of her head bigger, the middle portion of her body of the same size and that of the legs smaller. The following is the order of combinations for the magic mirror from the top.
(a) Plane, convex and concave | (b) Convex, concave and plane |
(c) Concave, plane and convex | (d) Convex, plane and concave |
Answer: (c) : As the image of head is bigger, the upper portion of magic mirror is concave. The middle portion of the image is of same size, so, middle portion of magic mirror is plane. Now, the image of legs looks smaller, therefore, the lower portion of magic mirror is convex.
(iv) To get an image larger than the object, one can use (a) convex mirror but not a concave mirror (b) a concave mirror but not a convex mirror (c) either a convex mirror or a concave mirror (d) a plane mirror.
Answer: (b) a concave mirror but not a convex mirror
(v) A convex mirror has wider field of view because (a) the image formed is much smaller than the object and large number of images can be seen (b) the image formed is much closer to the mirror (c) both (a) and (b) (d) none of these.
Answer: (c) both (a) and (b)
Question 2:
The lenses form different types of images when objects are placed at different locations. When a ray is incident parallel to the principal axis, then after refraction, it passes through the focus or appears to come from the focus.
When a ray goes through the optical center of the lens, it passes without any deviation. If the object is placed between the focus and the optical center of the convex lens, an erect and magnified image is formed.
As the object is brought closer to the convex lens from infinity to focus, the image moves away from the convex lens from focus to infinity. Also, the size of the image goes on increasing and the image is always real and inverted.
A concave lens always gives a virtual, erect, and diminished image irrespective of the position of the object.
(i) The location of image formed by a convex lens when the object is placed at infinity is (a) at focus (b) at 2F (c) at optical center (d) between Fand 2F
Answer: (a) at focus
(ii) When the object is placed at the focus of concave lens, the image formed is (a) real and smaller (b) virtual and inverted (c) virtual and smaller (d) real and erect
Answer: (b) virtual and inverted
(iii) The size of image formed by a convex lens when the object is placed at the focus of convex lens is (a) small (b) point in size (c) highly magnified (d) same as that of object
Answer: (c) highly magnified
(iv) When the object is placed at 2F in front of convex lens, the location of image is (a) at F (b) at 2 F on the other side (c) at infinity (d) between F and optical center
Answer: (b) at 2 F on the other side
(v) At which location of object in front of concave lens, the image between focus and optical centre is formed (a) anywhere between centre and infinity (b) at F (c) at 2F (d) infinity
Answer: (a) anywhere between centre and infinity

Q8: Do the laws of reflection hold good for spherical mirrors?
A8: Yes, laws of reflection hold good for spherical mirrors.
Q9: What do you understand by reflection of light?
A9: The phenomenon of bouncing back of light to the first medium from the surface of separation of two media is called reflection of light.
Q10: Is linear magnification always positive?
A10: No, it can be negative also. If the magnification has a plus sign, then the image is virtual and erect.
Q11: For driving a car, what type of mirror would you prefer to see the traffic at your back?
A11: We prefer convex mirror for observing the traffic behind us because its field of view is much larger than the plane mirror. However, it gives erroneous idea about the speed of the vehicles behind us.
Q12: One reads a newspaper due to the light reflected from it. Why then we do not see even faint image of ourselves in the newspaper?
A12: The newspaper causes scattering of light, which is an irregular and diffused sort of reflection. From each point, light goes in all directions. The image is seen only when there is regular refection of light. It is the homogeneous nature of the surface which causes irregular reflection or scattering of light.
Q13: Which part of the eye is reused when one donates the eye?
A13: The cornea of the donor is removed after the death of the person and transplanted in a blind person whose original cornea is opaque. Thus, the blind person gets sight.
Q14: What is meant by refraction of light?
A14: The bending of a ray of light as it passes from one medium to another is called refraction.

Light of all the colour travel at the same speed in vacuum for all wavelengths. But in any transparent medium (glass or water), the light of different colours travel with different speeds for different wavelength that means that the refractive index of a particular medium is different for different wavelength. As there is a difference in their speeds, the light of different colour bend through different angles. The speed of violet colour is maximum and the speed of red colour is minimum in glass so, the red light deviates least and violet colour deviates most. Hence, higher the wavelength of a colour of light, smaller the refractive index and less is the bending of light. \(\begin{equation} \lambda \end{equation}\) r > \(\begin{equation} \lambda \end{equation}\) v and r n < v n , \(\begin{equation} v=\frac{c}{\lambda} . \end{equation}\) (i) Which of the following statements is correct regarding the propagation of light of different colours of white light in air? (a) Red light moves fastest. (b) Blue light moves faster than green light. (c) All the colours of the white light move with the same speed. (d) Yellow light moves with the mean speed as that of the red and the violet light. (ii) Which of the following is the correct order of wavelength?
(iii) Which of the following is the correct order of speed of light in glass?
(iv) Which colour which has maximum frequency
(v) Which of the following is the correct order of angle of deviation?
The spreading of light by the air molecules is called scattering oflight. The light having least wavelength scatters more. The sun appears red at sunrise and sunset, appearance of blue sky it is due to the scattering of light. The colour of the scattered light depends on the size of particles. The smaller the molecules in the atmosphere scatter smaller wavelengths of light. The amount of scattering of light depends on the wavelength of light. When light from sun enters the earth's atmosphere, it gets scattered by the dust particles and air molecules present in the atmosphere. The path of sunlight entering in the dark room through a fine hole is seen because of scattering of the sun light by the dust particles present in its path inside the room. (i) To an astronaut in a spaceship, the colour of earth appears
(ii) At the time of sunrise and sunset, the light from sun has to travel. (a) longest distance of atmosphere (b) shortest distance of atmosphere (c) both (a) and (b) (d) can't say (iii) The colour of sky appears blue, it is due to the (a) refraction oflight through the atmosphere (b) dispersion of light by air molecules (c) scattering of light by air molecules (d) all of these. (iv) At the time of sunrise and sunset (a) Blue colour scattered and red colour reaches our eye (b) Red colour scattered and blue colour reaches our eye (c) Green and blue scattered and orange reaches our eye (d) None of these (v) The danger signs made red in colour, because (a) the red light can be seen from farthest distance (b) the scattering of red light is least (c) both (a) and (b) (d) none of these
Atmospheric refraction is the phenomenon of bending of light on passing through earth's atmosphere. As we move above the surface of earth, density of air goes on decreasing. Local conditions like temperature etc. also affect the optical density of earth's atmosphere. On account of atmospheric refraction, stars seen appear higher than they actual are; advanced sunrise; delayed sunset, oval appearance of the sun at sunrise and sunset; stars twinkle, planets do not. (i) Due to atmospheric refraction, apparent length of the day
(ii) Apparent position of the star appears raised due to
(iii) The sun appears oval shaped or flattened due to
(iv) Twinkling of stars and non-twinkling of planets is accounted for by
(v) In absence of atmosphere, the colour of sky appears

(i) (a): The angle between the two refracting surfaces of a prism is called angle of prism. (ii) (b): The angle between the incident ray and the emergent ray is called angle of deviation. (iii) (d): As the ray of light enters from rarer medium (air) to denser medium (glass), the angle of incidence is more than angle of refraction. (iv) (c): More be the refractive index, more be the angle of deviation and it also depends on the refractive index of prism. (v) (c): The refraction of light takes place through rectangular surfaces.
(i) (b) (ii) (b) (iii) (a) : The deviation is maximum for violet and minimum for red, so option (a) is correct. (iv) (a): The red light has a single wavelength and when enters a prism, it will not split into other different colours. (v) (b): The boundaries of colours in the spectrum produced by prism are not sharp, so the spectrum is impure.
(i) (c) : All the colours of the white light move with the same speed in air.

Case Study/Passage Based Questions
Question 1:
Corrosion is the phenomenon of deterioration of surface of metal in presence of air and moisture. It is a natural process and in the presence of a moist atmosphere, chemically active metals get corroded. This is an oxidation reaction. Rusting is the process where iron corrodes due to exposure to the atmosphere. The main circumstance of corrosion occurs with iron because it is a structural material in construction, bridges, buildings, rail transport, ships, etc. Aluminium is also an important structural metal, but even aluminium undergoes oxidation reactions. However, aluminium doesn’t corrode or oxidize as rapidly as its reactivity suggests. Copper (Cu) corrodes and forms a basic green carbonate.
(i) What is rusting?
(ii) Which two metals do not corrode easily?
(iii) Write the chemical name of the compound formed on corrosion of silver.
(iv) Corrosion is (a) a redox reaction (b) a reduction reaction (c) a displacement reaction (d) an oxidation reaction
