Model Mania

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...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

After a discussion of chemical reactions and electricity, scholars break into groups and follow a scripted activity to discover if fruit can power a clock. After a concluding discussion, the class a presented with a challenge.

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach the proper...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein) before,...

The heat of solution measures how much thermal energy a dissolving substance consumes or gives off. The experiment demonstrates both endothermic and exothermic reactions. Scholars dissolve several substances, measure the temperature...

Thinking back to the last time you taught a lesson on chemical changes ... was there no reaction? Check out an explosive video to put some spark back in your instruction! The narrator of the video guides you through the expectations, as...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in...

In this 21-day unit, students are introduced to the anchoring phenomenon-a flameless heater in a Meal, Ready-to-Eat (MRE) that provides hot food to people by just adding water. They complete investigations to collect evidence to support...
