Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Give your charges a charge with this clip on chemical reactions! Bill initiates some pretty flashy chemical reactions that you most likely won't be doing in your classroom. When you are teaching the difference between physical and...

What happens when chemical bonds break and form? Science scholars explore the movement of energy in a chemical system by watching a well-rounded video. The narrators illustrate exothermic and endothermic reactions in terms of temperature...

How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of...

Looking for a simple way to teach conservation of energy in chemical reactions? Pupils can observe energy changes as water forms during a chain reaction between oxygen and hydrogen using an interactive. The resource instructs users to...
