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

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this activity, learners discover that atoms and ions of different metals will change places.

These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners electrically plate zinc onto brass objects.
