Getting Down to Basics (and Acidics)

Seventh graders investigate acids and bases. In this acids and bases lesson, 7th graders use household items such as coffee, lemons and soap to define acids and bases. They observe a demonstration to show how indicators determine if a solution is an acid or a base. They observe red and blue litmus paper tests and they conclude the lesson by testing common household substances with litmus paper to determine if they are acids or bases.
