Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.

Safety Data Sheet

The rock cycle has been the subject of study for many years. A key component to the rock cycle is the mechanical and chemical erosion of rocks. In this kit students will learn about the rock cycle and the significance of certain types of erosion. This kit also provides an opportunity for students to investigate acid rain and other environmental factors that can be influenced by human actions. Also included is a demonstration that will help students visualize the freezing and thawing action of water on rocks. With multiple activities, this is a kit that is sure to keep students engaged throughout the whole experiment.
