Proceed to the tennis court and have the students take turns dropping
the tennis ball down from different step heights on the
step ladder. Have them drop it straight down as well as at an angle. Emphasize to the students that you want them to observe how
the ball bounces on the court (at what angle of rebound). Have the
student drop the ball slowly, moderately and quickly to observe the
variations in the angle of rebound. Have an assistant who writes down
the observations of the person dropping
the ball. (Each student will need to have one sheet of paper on the clip
board for their observations).

|
After each student has had a turn dropping the ball from the step
ladder, return to the classroom and discuss the observations that the
students have made.
|
|
Ask the students to then use their observation sheet and record their
findings on graph paper.
|
|
Display the graph paper findings on a Bulletin Board in the
classroom.
