Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.
