Mike (my husband) and I have each been teaching our grandsons, ages 7 and 9, (who live in Chicago) every week via Zoom.
I taught them about the body systems and how they relate to each other, including the brain, the ear, and other parts of the body.
We do experiments for each lesson which are fun to do.
Mike taught them about gravity, volume, and other scientific stuff.
He does experiments as well.
A highlight was when Mike taught them how to make a telephone out of two paper cups and string as we did when we were kids.
This has been a great way to spend extra time with them.
