Other examples are shown as well.
One of the first animation assignments at the Disney company in the 40's was a bouncing ball exercise. Animators were to make a ball appear to bounce across the page. Some took the exercise further and put a ring around the ball to show how it rotated as it bounced while others made surprise endings like an explosion on the final bounce.
One of the first drawn animation assignments for our students is a bouncing ball flip book where students use one side of the flip book to make a bouncing ball and on the reverse side they create their own animation. Squash and stretch principles are emphasized. Below is an example of the timing and squash/stretch of the ball as we animate it.
Evaluation:
2 points -- Bouncing ball
Remaining points go toward the second animation students do on the opposite side of the flip book:
2 points -- Neatness
3 points -- Smoothness of motion
3 points -- Utilization of squash and stretch principles
10 points total.
