Materials List for How High Will It Bounce?
–Second Grade Physical Science -Bouncing Lesson
–measuring tape
–painter’s tape
-marker
–ruler
-string
-12 different types of balls
Step 1: Download the Second Grade Physical Science -Bouncing Lesson and complete the worksheet
Here is a sample page from our worksheet for this lesson:
Step 2: Measure the circumference of each ball
Use the string and wrap it around the ball at its equator. Mark on the string how large the ball is at that point and hold up the string to the ruler. This small green ball has a circumference of 3 inches.
This larger wiffle ball has a circumference of 11 inches.
Step 3: Drop each ball from a high height
Get out the measuring tape and gently drop each ball from a high height, such as a table. Use the same amount of force each time you drop the ball and drop each one onto the same surface.
Measure where the middle of the ball bounces to on the tape measure.
Here we are measuring the height of bounce a ping pong ball has.
Step 4: Drop each ball from a low height
Here is a video showing how we set up our low ball drop:
We marked all the bounce heights with painter’s tape on the wall so we could compare the differences.
