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

When collecting evidence at a crime scene, investigators may encounter substances that they are not able to identify in the field. These substances will be sent to a crime lab, where a forensic scientist will work to analyze and identify them. In this experiment, students will take on the role of a forensic scientist and use their observation skills, senses, and a series of chemical tests to determine the identity of two mystery substances. Kit contains an Instruction Manual and enough materials for 2 groups of students.
