In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.
