Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...

Add a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.

A penny can be a much more valuable teaching tool that you might think. Whether you are teaching about chemical reactions, surface tension, the behavior of gases, or are just looking for engaging activities for early finishers,...

Let's have a gas. Individuals mix baking soda and vinegar in a bottle. Learners view the interaction between the solid and the liquid and notice that a gas is formed. Scholars notice the gas inflates a balloon stretched across the mouth...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Bring out some bubbly! Individuals perform the classic baking soda and vinegar experiment with a twist. Learners add a drop of dish detergent to make the bubbles last longer. They vary the amount of baking soda and vinegar in an effort...

Engaging hands-on science lessons for grades 2-6 on chemical and physical changes.

Create a dough using simple ingredients and make it bubble like a brew in a cauldron by causing an acid-base reaction.

Science activity shows what happens when a bag can't hold any more carbon dioxide.

Science activity shows what happens when an orange or clementine is mixed with baking soda. Links to video of the experiment.

Turn your pumpkin into a volcano science activity shows what happens when water, food coloring, dish soap, and vinegar are mixed with baking soda. Click on the link to watch Scientist Joe make the Jack-O-Cano experiment.

Watch Scientist Joe make a volcano using common household products in this video presentation.
