© Science Department Edited_2025 1 Secondary 4 Science Physics Practical Revision Paper 2025 (Self-Directed Learning) Name: _____________________ ( ) Class: _______ Date: _____________________ 1 In this experiment, you will investigate how the amount of water in a container affects the periods of water wave oscillations. You are provided with: • a container • a 30 cm ruler • a 50 cm3 measuring cylinder • a stopwatch Fig. 1.1 Experiment 1 1. Use a 50 cm3 measuring cylinder to measure 50 cm3 of water, then pour it carefully into the container. 2. Hold one side of the container approximately 3 cm above the bench, then release it carefully so it falls to the bench. 3. Immediately after Step 2, start the stopwatch and record the average time taken, < t >, for 20 oscillation of water. Fig. 1.1 shows the set up for Experiment 1. BENCH 3 cm 3 cm container water

T = ____________________ s [2] (c) Repeat Experiment 1 five times, each time using a different volume of water, and record all your results in the table below. Volume of water / cm3 20 oscillations T / s t1 / s t2 / s < t > / s 50 100 150 200 250 300 [6] (d) On page 3, use your data to plot a suitable graph. [4] (e) Identify one source of error in your experiment which might affect the results you collected, and suggest a way to improve it. __________________________________________________________________ __________________________________________________________________ _______________________________________________________________ [2]
