Gummy Bear Experiment Concepts

This video tutorial from Mumu Math and Science explains how to calculate percentage change using a gummy bear lab experiment. The process involves soaking a gummy bear in water, measuring its dimensions and mass before and after soaking, and then applying the percentage change formula. The video provides step-by-step examples of calculating percentage change for length, width, and mass, and concludes with a mention of additional resources available in the show notes.
