About this deal

Using the Bouncing Ball Class Kit, students can construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

Your homemade bouncy balls use a variation of one of our five basic slime recipes. All our slime recipes are super easy to make for a fun activity anytime! We make slime all the time, and these have become our go-to favorite slime recipes! This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below. Students can the Bouncing Ball Class Kit to make observations and measurements to identify materials based on their properties. When the glue mixture was added to the borax, the borax acted as a cross-linker, hooking the glue’s molecules together to form the rubbery bouncy ball. We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration and kids love it too!Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!What’s slime science all about? The borate ions in the slime activators(sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. This is called cross-linking! It does and you can use slime making to explore states of matter and its interactions. Find out more below… Then she added a couple drops of food coloring to the glue/cornstarch mixture and gave it a little stir. She was hoping to get a swirled bouncy ball but it turns out the food color really gets mixed thoroughly when forming the ball. Using the Bouncing Ball Class Kit, students can develop models to describe the atomic composition of simple molecules and their structures or properties.

Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like the clump of spaghetti! Is slime a liquid or solid? Make sure to wash your hands after making and playing with your bouncy balls. Wash all surfaces too! See slime safety notes here. Students can gain firsthand experience with polymers and learn more about synthetic materials and where they come from.

The Science Behind It

Note: If let to sit, the ball will become flat on one side. Simply rolling it between your hands should make it round again. Polymers, long strands of molecules, behave in a similar way as the long strands of spaghetti. If the long molecules slide past each other, the substance acts like a liquid (like the liquid glue). Students can use the Bouncing Ball Class Kit to plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. 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.

To make your own borax bouncy balls you will use a variation of our Borax Slime recipe. Where do I buy borax powder? The first step to making the bouncy balls was to prepare the borax and water mixture. My 5 year old daughter measured out 1/2 cup of warm water and 1 T of borax. Then she gave the mixture a good stir to dissolve the borax. STEP 4: Time to dig in with your hands. Begin kneading one of the glue mixture globs, working with one blob at a time. Once the ball was formed, it was ready to bouncy. Although it didn’t bouncy nearly as high as the super bouncy balls she was familiar with, my daughter still had a ton of fun throwing it around the house.Using the Bouncing Ball Class Kit, students can investigate, gather and make sense of information about synthetic materials. The ball can bounce because of the cross-linked polymers. Since the long polymer chains are flexible, when the ball hits the ground, it is able to momentarily deform or squish.

The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until… STEP 3: Now you can go ahead and pour 3 globs of the glitter/glue mixture into the water/borax mixture. Now my daughter was ready for the fun and gooey part. She poured her glue mixture into the borax water and let it sit for about 10-15 seconds. The glue mixture started to harden and could be removed easily with a fork. We call it a Non-Newtonian fluid because it’s a little bit of both! Did you know that slime aligns with the Next Generation Science Standards (NGSS)? The measurements are a little forgiving so we found it easiest to use a 1/4 cup measuring cup filling it halfway with glue (2 T) before adding the 1 T of cornstarch. Using a measuring spoon to measure the glue turned out to be more messy than estimating the 2T of glue in the 1/4 cup wearing cup.
