Why Does a Stretched Rubber Band Hold Energy?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why does a stretched rubber band hold energy?

The Big Idea

A stretched rubber band can fling a paper ball across a room. That is because stretching stores energy. Let's see how it works!

Stretch It Out

Step one: stretch it out. When you stretch a rubber band, you push its stretchy material out of its natural shape. Your arm muscles spend energy to do that.

It Wants Back

Step two: it wants to go back. The material wants to return to its normal shape, so it holds the energy like a coiled spring. The farther you stretch it, the more energy it holds.

Let Go

Step three: let go. When you let go, the stored energy turns into motion energy. The band snaps back, and anything in its way gets flung!

A Closer Look

Let's take a closer look! A relaxed band has no extra energy. A stretched band holds stored energy. A bigger stretch stores more energy. Letting go turns it into motion.

Quick Facts

Quick facts! A stretched rubber band stores energy just like a coiled spring. Remember, the farther you stretch it, the more energy it holds. When you let go, that stored energy turns into motion. Always aim away from faces, and ask a grown-up to watch.

Think Like a Scientist

Now, think like a scientist! With a grown-up watching, stretch a rubber band a little. Shoot a paper wad into an empty space. Now stretch it a lot and shoot again. Which stretch sent the wad farther? Then explain what you learned to a friend.

Outro

A stretched rubber band stores energy, and letting go turns it into motion. Science is amazing! Keep wondering and keep exploring! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
