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

Description
Amino acids are the fundamental building blocks of all proteins. Often times scientists may need to identify the amino acid contained in a protein. One such method for separating and identifying individual amino acids is paper chromatography. In this activity, students will perform a paper chromatography experiment on three known amino acids, and then use their results to identify the components of an unknown amino acid mixture. This kit contains enough material for 15 groups. Teacher's Manual and Student Study Guide copymasters are included.
