Amy and the Secret Bounce: The Science of How Balls Bounce
Join Amy to discover the science of how balls bounce! Learn about elasticity and deformation with Jingle the cow, Flapper the duck, and Piggly the pig.
Best quote from Amy and the Secret Bounce: The Science of How Balls Bounce
When a real bouncy ball hits the floor, it stores energy in its skin as it gets dented, then snaps back so fast that it launches itself away from the ground. This is actually called being 'elastic,' and it's a lot like how joy is an energy that just has to go somewhere.

Frequently Asked Questions
The secret is that a bouncy ball isn't just a solid piece of rubber; it acts like a tiny superhero. When the ball hits the ground, it undergoes deformation, changing from a perfect circle into a flat pancake shape for a split second. Because of its elastic material, the ball pushes back against the ground to regain its shape, resulting in a high-five with the Earth that sends it flying back into the air.
Elasticity is the super cool property that allows a ball to return to its original circular shape after it squishes against the ground. In Amy and the Secret Bounce, we learn that the ball doesn't want to stay squished like a pancake. This desire to return to its original form creates the force necessary to push off the ground, demonstrating the physics of bouncing balls in a fun, sunny garden setting.
The story features several fun animal friends who help illustrate the science of bouncing. You will meet Jingle the cow with her shiny jingling bell, Flapper the duck who waddles around the garden, and Piggly the pig. These characters help explain concepts like deformation by comparing the ball's squish to a soft plushie or Piggly rolling in the mud, making science for kids easy to understand.
