What's the Matter with My Jell-O?

Students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. Styrofoam, sugar, salt, and room temperature treatments are compared to control Jell-O to investigate the effect of these treatments on the phase change of Jell-O from liquid to solid (freezing point). The Take It Further section explores the environmental pros and cons of using salt (one of the Jell-O treatments) to improve roadway safety. The Family Page extends this learning to the community by providing families with challenges to explore at home.
