Thanksgiving Science Activities/STEM ideas for busy moms
The clear winner for STEM ideas was the super secret spy messages. The kids painted with a mix of baking soda and water. This sounds like a complete bore because you can’t see the art…yet. As their drawings are drying we boiled cranberries in a little water. The girls loved hearing them pop in the pot. We cooled the dark red water and loaded it into a spray bottle to spray on their drawings. Anywhere there was baking soda will turn a dark green, while the remaining areas will be bright red!
I love that this activity combines art with science, and can even combine history too if you decide to talk about the spice routes that brought Columbus over. Why does cranberry juice change color when it hits a base? It comes down to the molecule changing, you can learn all about it in depth in our kids’ pH activity!
Dr. Erica develops kids science curriculum that is not only fun but also teaches real science. Many of her projects, like developing a mass spectrometer to sort pennies and nickles are inspired, and tested, by her two daughters. She has a Ph.D. in Physics from Boston University and spent many years teaching and tutoring at the University and High School levels before diving head first into the world of kids science.
