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
Chlorophyll is the most prevalent and well-known plant pigment related to photosynthesis. It is not, however, the only pigment necessary for photosynthesis to occur. Other pigments are also involved in the process, though they are often overlooked as they tend to be masked by the abundance of the green pigment chlorophyll. In this activity, students will use paper chromatography to separate the various pigments from a sample of plant pigment extract. Students will not only confirm the presence and learn the role of these "hidden" pigments, but will also learn about chromatography as a technique for separating molecules. Kit contains an Instruction Manual and enough materials for 2 groups of students.
