JoinIndicators for Inquiry
Fifth-grade students use homemade plant-based acid/base indicators to learn about matter at an age-appropriate level and develop process skills. As a result of completing this lesson sequence the students should be able to perform many tasks using process skills such as observing chemical changes; identifying acids and bases by performing tests; classifying common household substances as acidic, basic (alkaline), or neutral; and developing a scheme for solving a performance-based scenario.
