Purpose
The purpose of this experiment is to investigate and record the different bounce heights of the bouncy balls once their original recipe have been modified.
Background
The bouncy ball experiment is an experiment where you mix cornstarch, borax and glue to create a small ball that rebounds upon impact, also known as elasticity. After my ball was made, I recorded data about how high my ball bounced at a drop height of 50cm.
The objective of this experiment is to maximise the elasticity effect of the bouncy ball, by investigating the ingredients and their properties when alone, and when mixed with other chemicals. The intended result of this experiment is a rubber like, spherical polymer ball which bounces upon impact. This was accomplished …show more content…
Borax is a naturally mined chemical, which has very low danger levels, therefore it is a very safe material to use in everyday tasks (wellnessmama.com 2016). In this experiment, borax is used to bond a polymer in cornstarch called amylopectin to a polymer in glue, called polyvinyl (http://www.hometrainingtools.com/a/make-a-colorful-bouncy-ball , 2016). Cornstarch is a corn product primarily used for cooking purposes, also widely used as a thickening agent.
This bond gives the ball its elasticity effect, which means that the ball wants to return to its native shape when its shape is change. So when you throw it against a surface, the ball gets compressed, but because of the polymer bond between the cornstarch and the glue, the ball returns to its native shape which makes the ball “bounce”. The borax also plays an important role in the chemical reaction, the borax is the ingredient that bonds the two polymers together, and keeps them together during impact.
Hypothesis If the ball bounces higher when more cornstarch is added, then the polymer bonds are stronger because the cornstarch is what makes the polymer bonds that give the ball its
