List of experiments for ICSE Class 9 Physics Practical.

Experiments List as Follows:-

1. Determine the least count of the Vernier calipers and measure the length and diameter of a small cylinder (average of three sets) – may be a metal rod of length 2 to 3 cm and diameter 1 to 2 cm.
2. Determine the pitch and least count of the given screw gauge and measure the mean radius of the given wire, taking three sets of readings in perpendicular directions.
3. Measure the volume of a metal bob (the one used in simple pendulum experiments) from the readings of water level in a measuring cylinder using the displacement method. Also, calculate the same volume from the radius measured using Vernier calipers.
4. Obtain five sets of readings of the time taken for 20 oscillations of a simple pendulum of lengths about 70, 80, 90, 100 and 110 cm; calculate the time periods (T) and their squares (T²) for each length (l). Plot a graph of l vs. T² . Draw the best – fit straight – line graph. Also, obtain its slope. Calculate the value of g in the laboratory. It is 4π2 x slope.
5. Take a beaker of water. Place it on the wire gauze on a tripod stand. Suspend two thermometers – one with Celsius and the other with Fahrenheit scale. Record the thermometer readings at 5 to 7 different temperatures. You may start with ice cold water, then allow it to warm up and then heat it slowly taking temperature (at regular intervals) as high as possible. Plot a graph of T_Fvs T_c. Obtain the slope. Compare with the theoretical value. Read the intercept on T_F axis for T_C = 0.
6. Using a plane mirror strip mounted vertically on a board, obtain the reflected rays for three rays incident at different angles. Measure the angles of incidence and angles of reflection. See if these angles are equal.
7. Place three object pins at different distances on a line perpendicular to a plane mirror fixed vertically on a board. Obtain two reflected rays (for each pin) fixing two pins in line with the image. Obtain the positions of the images in each case by extending backwards (using dashed lines), the lines representing reflected rays. Measure the object distances and image distances in the three cases. Tabulate. Are they equal? Generalize the result.
8. Obtain the focal length of a concave mirror (a) by distant object method, focusing its real image on a screen or wall and (b) by one needle method removing parallax or focusing the image of the illuminated wire gauze attached to a ray box. One could also improvise with a candle and a screen. Enter your observations in numbered rows.
9. Connect a suitable dc source (two dry cells), a key and a bulb in series. Close the circuit by inserting the plug in the key. Observe the bulb as it lights up. Now open the circuit, connect another identical bulb in between the first bulb and the cell so that the two bulbs are in series. Close the key. Observe the lighted bulbs. How does the light from any one bulb compare with that in the first case when you had only one bulb? Disconnect the second bulb. Reconnect the circuit as in the first experiment. Now connect the second bulb across the first bulb. The two bulbs are connected in parallel. Observe the brightness of any one bulb. Compare with previous results. Draw your own conclusions regarding the current and resistance in the three case.
10. Plot the magnetic field lines of the earth using a small compass needle. On another sheet of paper, place a bar magnet with its axis parallel to the magnetic lines of the earth, i.e. along the magnetic meridian or magnetic north-south. Plot the magnetic field in the region around the magnet. Identify the regions where the combined magnetic field of the magnet and the earth is (a) strongest, (b) very weak but not zero, and (c) zero. Why is neutral point, so-called?
11. Using a spring balance obtain the weight (in N) of a metal ball in the air and then completely immersed in water in a measuring cylinder. Note the volume of the ball from the volume of the water displaced. Calculate the upthrust from the first two weights. Also, calculate the mass and then the weight of the water displaced by the bob M=V.ρ, W=mg). Use the above result to verify Archimedes principle.
12. To determine the density of a liquid (other than water) by using a spring balance and a measuring cylinder.
13. To determine the density of a non-porous solid (insoluble and denser than water) by using a spring balance and a measuring cylinder.
14. To show that gases are readily compressible and liquids are not.
15. To determine the boiling point of water and melting point of ice.
16. To prepare a saturated solution of common salt in distilled water and to determine its solubility at room temperature.
17. To study the third law of motion using two spring balances.
18. To verify Archimedes’ principle.
19. To establish the relation between the loss in weight of a solid when fully immersed in (i) tap water; (ii) strongly salty water, with the weight of water displaced by it by taking at least two different solids.
20. To plot temperature–time graph for a hot object as it cools
21. To study the effect of amplitude on the time period of a simple pendulum.
22. To study the variation in time period of a simple pendulum with its length.
23. To study the effect of mass on the time period of a simple pendulum
24. To determine the speed of a longitudinal pulse propagated through a stretched slinky.
25. To study the reflection of sound.
