Corny Polymer Balls STEM Challenge
By: Patty House, OSU Extension Educator, 4-H Youth Development
The Problem
The 4-Clovers Toy Company is looking to change the formula they use to make a popular bouncing ball. Market studies show that consumers want to purchase disposable bio-friendly toys. The company’s senior chemist has requested that biodegradable ingredients be studied for their practical use in the bouncing ball’s new formula.
The Challenge
To develop and test a hypothesis to determine the practical use of glue, borax, and corn starch to enhance the bounce factor for a children’s disposable toy ball.
