In this reactions worksheet, students write the formula for each reactant and product and then balance the equation. Students have 23 problems to solve.

In this salts worksheet, students read how salts are created and how different acids make different salts. This worksheet has one graphic organizer and seven short answer questions.

Students perform flame tests on salts and record the electron configurations for various cations. They analyze and record the results using spectroscopes.

For this chemical equations worksheet, students are given the trends for the reactions between the alkaline earth metals with water, the solubility of the Group II hydroxides and the solubility of the Group II sulphates.

Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy. .

In this chemical reaction worksheet, students write 11 balanced equations for 11 word equations, and complete word equations and balance chemical equations for 13 chemical equations.

In this balancing equations worksheet, students determine the type of reaction and write the balanced equation. Students read the word description and write the symbol of each element using the periodic table.

Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Students explore conductivity and productivity in aquatic systems.

De-icing materials may have a harmful effect on our environment; have your class perform an experiment to test the nature of these effects. Scholars monitor the survival rate of a sample of daphnia as the concentration of a de-icing...
