Chemical Tests

This unit introduces third-graders to the science of chemistry to determine the identity of five common household chemicals: sugar, alum, talc, baking soda, and cornstarch.

Students focus on the physical properties of color, form, and texture. Next, they explore chemical properties by observing how the five powders interact with water, vinegar, iodine, and red cabbage juice. These tests explore phenomena such as crystallization, evaporation and filtration.

Finally, students apply their skills and their knowledge of the five chemicals to identify a variety of "mystery" mixtures. Students develop scientific skills such as observing and recording results, forming conclusions on the basis of experience, communicating results, and applying their knowledge to solve problems.
