In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
