Farm Chemistry (Ages 10+)

Farmers in 1790s New England didn’t know the chemical formulas of acids and bases, but they still knew how to use them. We need acids and bases to make soap, treat unbalanced soil, cook, and many other things, but they can also be dangerous. Join us to learn about the rules people taught each other to protect themselves from these fascinating chemicals. We will use cabbages to create a colorful acid/base indicator, and lemons to create secret messages with invisible ink.
