Chemistry

Workhorse studio concept for the American Association of Chemistry Teachers. This app has not been commissioned or approved by AACT.

The course

Every topic has the same three parts. The order depends on the topic: some start at the bench, some start with reading.

Learn
Read the ideas, with a check after each part.
Lab
Predict, run it, and say what you saw.
Practice
Answer questions. Each answer says why.
