Tobar Make Your Own Bouncy Balls Craft Kit

Product Information

I blogged before about cleaning some two pence coins with vinegar , and how they got a turquoise tinge after washing if we didn't rinse off the cleaning solution. The mould was easy to open, but one half stuck in to the extent that it seemed the ball would break rather than it coming out, and I had to get a knife to assist it.

The included glitter and colored compounds let you customize your new toy—you can even make a glow-in-the-dark ball! Creative kids can opt for funky patterns, draw on a message or perhaps a face or name, whatever they decide - it’s a whole new ball game! Kids will love mixing their own designs and playing with their colourful balls with this Make Your Own Bouncy Balls kit.

Students use initial and final bounce heights to determine the energy lost to the environment during a bounce. The instructions said to fill the mould 95% full, which requires a bit of estimating - we didn't quite get this right and should have put a little more in - I think the granules probably need to come up to the 'neck' of the mould, rather than sitting a little below. This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below. First mix the included glitter and activator compounds together like kneading dough, then fill the pre-made mold to form your desired shape, wait just 10 minutes, and you're ready to bounce! It didn't even tell you what you were making the ball from, which to my mind is a missed opportunity to introduce children to a bit of science whilst they are having fun.

Galt have come up with a kit that allows children to create their very own bouncy balls from scratch.With everything you need included in this brilliant STEM set, the Bouncing Balls set let's you discover science in an easy way. You provide the water and in just a few minutes, your students will be able to use their creations to conduct a wide range of investigations. The kit can be used to reinforce students' mastery of lab procedures, as an unforgettable introduction to polymers, or even as an energy lab (measuring bounce heights). Our all-in-one starter set lets little ones can create up to 43 individual power balls in every fabulous shade of the celestial rainbow.

Once the gaps are filled, the polymers start to expand again, releasing the energy they absorbed and making the ball bounce.This was a fairly simple way to demonstrate irreversible change with my second graders while working on following directions.
