Coronavirus. COVID-19. Lately, I’m sure you’ve heard a lot about Coronavirus.

This lesson is the second STEM lesson plan which explores different Coronavirus topics.

This lesson builds upon the last lesson plan (soap vs sanitizer) to explore more about handwashing: specifically, whether soap or no soap is better and how long is safe to wash your hands.

These lessons will help you and your child understand the science and math behind coronavirus and how to make sure your community stays safe!

If your child cannot read, read the text out loud to them. Ask them the questions and have them respond and/ or solve on a separate sheet of paper. If your child can read, simply give them the second page of this handout and have them read the text out loud or in their head. Materials: Blank paper, pen or pencil, internet access/YouTube
