Acids and Bases Unit for Middle School Science

Do you need a little help with teaching acids and bases to your middle school science class?

This unit will keep your class engaged, and with five days of activities, will save you tons of time!

Students will learn about acids and bases, identify the pH of solutions, and learn about how we interact with acids and bases every day.

Your class will learn that ions are what determine whether a substance is an acid or a base. They will also learn about the neutralization reaction and learn what happens when an acid and base are combined.

I am super excited to have found this great set of labs. It includes reading passages, worksheets and TWO labs! My students had so much fun with the cabbage water lab.
