Mystery of the Eleven Unknown Substances
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.
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
High schoolers gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.
