Print Prep

This lesson develops the idea that chemical reactions create new materials that have useful and interesting properties. The Great Goo Experiment is a two-part activity. In Part 1, students experiment by combining different substances and watching for reactions. In Part 2, students mix glue and borax solution in clear plastic bags to observe the reaction, which creates "Mystery Goo."
