Ball Drop Lab I. Prelab A. Purpose: To design and implement an experiment that examines the drop height versus the bounce height of an object. B. Problem: Is the height from which a ball is dropped related to the height it bounces to. Ball Drop Lab C. Hypothesis: If a ball is dropped from a continually greater height, then it will bounce higher. D. Materials: Various types of balls, meter sticks, bouncing surface (Identify your variable and controls before you start the procedure) E. Procedure: 1. Gather or find the required materials: 3 different types of balls, a meterstick and a bouncing surface. Ball Drop Lab (procedure continued) 2. Use one of the balls (ball “A”), measuring from the bottom of the ball, drop it from a height of 10 cm off the bouncing surface. 3. Measure the distance the ball bounces to, using the bottom of the ball as a reference. ( This will be a best guess based on the quickness of the event). 4. Repeat steps 2 & 3 two more times for ball “A” 5. Average the results for 10 cm and record. Ball Drop Lab (procedure continued) 6. Repeat steps 2-5 for the distances 20 cm through 100 cm for ball “A”. 7. Repeat steps 2-6 for ball “B”. 8. Repeat steps 2-6 for ball “C”. F.
