Tobar Make Your Own Bouncy Balls Craft Kit

Product Information

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. 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)?

Students can the Bouncing Ball Class Kit to make observations and measurements to identify materials based on their properties. 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. 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? 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.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… 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.

Make sure to wash your hands after making and playing with your bouncy balls. Wash all surfaces too! See slime safety notes here. This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.STEP 3: Now you can go ahead and pour 3 globs of the glitter/glue mixture into the water/borax mixture. 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! 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. 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!
