Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.
