Equilibrium: What Is It?
Tenth graders investigate chemical, physical and mechanical equilibrium. In this equilibrium activity, 10th graders participate in a physical activity to show equilibrium by some students standing and some students sitting at the same...
Curated OER
Experimenting with Physical Changes
Fourth graders explore physical changes. They discuss that physical change is a change in size, shape, or state of matter of a substance. Students explore what change takes place when two substances can dissolve each other. They observe...

UP AND ATOM
If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...
Curated OER
Sometimes, solid + liquid = gas
Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...
Curated OER
Chemical Changes by Gems
Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.
