Simple Science: Drops of Water on a Coin

Around here, we love doing Science Experiments, but we are all about SIMPLE science activities that require little to no prep!

This activity gifted us with so many opportunities to tie together all kinds of different things we have learned together over the years.

I love teaching and learning that way. It just works!

The first time we tried this activity at home, I wasn’t sure if my younger kids would have the patience to join in with their older siblings, but they did.
