Description:

In this activity (on pages 19-24 of PDF), learners soak chicken bones or eggshells in vinegar for several days. Learners observe what happens to the material as the acid dissolves the calcium that provides the strength to the material. The lesson includes information about calcium, calcium-rich foods that keep bones strong, and an explanation of how the acidic vinegar solution causes the bone or eggshell to become weak.
