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.

Description
Students will design a buffer that can maintain a pH within a narrow range when certain amounts of acid and base are added. The activity contains enough materials for 15 groups of students as well as a Teacher's Guide and Student Study Guide Copymasters. This lab meets Big Idea 6, Investigation 16, Primary Learning Objective 6.18.
