CBSE Class 11 Physics Practical Exam : Viva , Syllabus and Tips to Score Maximum Marks
CBSE Class 11 Physics Practical Exam: Evaluation Scheme
The record to be submitted by the students at the time of their annual examination has to include:
• Record of at least 15 Experiments {with a minimum of six from each section}, to be performed by the students.
• Record of at {least 5 Activities with a minimum of 2 each from section A & section B}, to be demonstrated by the teachers.

Time Allowed: 3 hours

Maximum Marks: 30

Two experiments: one from each section8 + 8 Marks
Practical record [experiments & activities] 6 Marks
Investigatory Project 3 Marks
Viva on experiments, activities & projects 5 Marks

Total =30 Marks

List of Experiments – Section A

1: To measure diameter of a small spherical/cylindrical body and to measure internal diameter and depth of a given beaker/calorimeter using Vernier Callipers and hence find its volume.
2: To measure diameter of a given wire and thickness of a given sheet using screw gauge.
3: To determine volume of an irregular lamina using screw gauge.
4: To determine radius of curvature of a given spherical surface by a spherometer.
5: To determine the mass of two different objects using a beam balance.
6: To find the weight of a given body using parallelogram law of vectors.
7: Using a simple pendulum, plot its L-T2 graph & use it to find the effective Length of second’s pendulum.
8: To study variation of time period of a simple pendulum of a given length by taking bobs of same size but different masses & interpret the result.
9: To study the relationship between force of Limiting friction and normal reaction & to find the coefficient of friction between a block and a horizontal surface.
10: To find the downward force, along an inclined plane, acting on a roller due to gravitational pull of the earth & study its relationship with the angle of inclination θ by plotting graph between force and sin θ.

Important Activities (for the purpose of demonstration only)
1: To make a paper scale of given least count, e.g., 0.2cm, 0.5 cm.
2: To determine mass of a given body using a metre scale by principle of moments.
3: To plot a graph for a given set of data, with proper choice of scales and error bars.
4: To measure the force of limiting friction for rolling of a roller on a horizontal plane.
5: To study the variation in range of a projectile with angle of projection.

List of Important Experiments – Section B

1: To determine Young’s modulus of elasticity of the material of a given wire.
2: To find the force constant of a helical spring by plotting a graph between load and extension.
3: To study the variation in volume with pressure for a sample of air at constant temperature by plotting graphs between P and V, and between P and 1/V.
4: To determine the surface tension of water by capillary rise method.
5: To determine the coefficient of viscosity of a given viscous liquid by measuring terminal velocity of a given spherical body.
6: To study the relationship between the temperature of a hot body and time by plotting a cooling curve.

Activities (For the purpose of demonstration only)

1: To observe change of state and plot a cooling curve for molten wax.
2: To observe and explain the effect of heating on a bi-metallic strip.
3: To note the change in level of liquid in a container on heating and interpret the observations.
4. To study the effect of detergent on surface tension of water by observing capillary rise.
5: To study the factors affecting the rate of loss of heat of a Liquid.
6: To study the effect of load on depression of a suitably clamped metre scale loaded at (i) its end (ii) in the middle.
7: To observe the decrease in pressure with increase in velocity of a fluid.

Tips to score well in CBSE Class 11 Physics Practical:

Your performance in Class 11 Physics Half Yearly exam will most likely to affect your Class 11 Physics practical exam’s score. If you have scored well in Half Yearly then most likely you will get good marks and vice versa.
• Learn about basic concepts.
• Thoroughly read the complete theory behind each experiment you have performed in the Physics laboratory.
• Also, revise whatever your subject teacher had taught you in your Physics class.
