## Activity 6.4: Let us explore

### Question 1

*Activity*

Take each ball and drop it from a fixed height.

**Solution**

1. This activity demonstrates how different materials behave when dropped from a fixed height.
2. Observation: When tennis balls, cricket balls, and hand exercise balls are dropped from the same height, they show different levels of bounce due to the properties of the materials they are made of.

**Answer:** The balls are dropped from a fixed height to observe their bouncing property.

### Question 2

*Activity*

Note the height to which the ball bounces and record it in Table 6.2.

**Solution**

1. The height to which each ball bounces after hitting the ground is noted.
2. Observation: The tennis ball shows a high bounce, the cricket ball shows a medium to low bounce depending on the surface, and the hand exercise ball shows a low bounce.

**Answer:** The bounce levels are recorded in Table 6.2 as high, medium, or low.

### Question 3

*Activity*

Identify the ball that achieves the highest bounce.

**Solution**

1. Compare the recorded bounce heights of all the tested balls.
2. Observation: The tennis ball achieves the highest bounce among the given options due to the resilient material and air pressure inside it.

**Answer:** Tennis ball achieves the highest bounce.
