This hands-on experiment allows students to witness a clear phase change from solid to liquid, while learning key vocabulary about variables and implementing the scientific method. The lab focuses on giving students the opportunity to select the independent variables they are going to be testing to create the ultimate gummy invertebrate. Using the enticement of creating your own candy, students learn how to create a controlled experiment and combine data to create a synthesized conclusion. The lab uses background knowledge of water and metric measurements to help students determine how to make the ultimate gummy worm.
