Everything You Need Is In The Kit: our bounce ball kit provides 12 cups with all the necessary crystal powders, molds, and instructions to make your own ball!

There are ten sachets of granules included (two of each colour) so between four and ten balls can be made.

Using the Bouncing Ball Class Kit, students can investigate, gather and make sense of information about synthetic materials.

The plastic mould comes in two pieces which slot together and can be separated later in the process. I've seen a few kits to make bouncy balls for sale, and I recently bought a cheap one to give it a go as they looked like some fun science and I thought my 4 year old might enjoy it. Students can use the Polymers and molds to plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.An ideal craft idea to get stuck into on rainy days or in the school holidays, kids will love making and designing their own bouncy balls. 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. Neither Achieve nor the lead states and partners that developed the Next Generation Science Standards were involved in the production of, and do not endorse, this product.
