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.


Changes to the carbon cycle and climate due to human activities have had detrimental effects on the environment. One example of this is known as ocean acidification, which is the changing of the ocean's chemistry due to increased carbon dioxide in the atmosphere and ocean. In this activity, students will learn about the carbon cycle and how it relates to ocean acidification. Through three different activities, students will investigate the cause of ocean acidification, and the effects it can have on the
ecosystem and marine life. Kit contains enough materials for 15 groups of students. Teacher's Manual and Student Study Guide Copymasters are included.
