As scientists, we are sometimes asked or would simply like to “do something sciency” for a local school or a kid for whom we’re an important adult. Here are a few “DIY” or “open” science activities that I’ve designed to be both didactic and fun and have done in partnership with classroom teachers at the lower elementary level.
Color changes! Bubbling solutions! Snacks! There is nothing not to love and are many obvious things to do with purple cabbage juice, an all-natural, non-toxic, brilliantly-colored pH indicator.
There are forces you can not see! What do magnets attract? Are some magnets stronger than others?
What do we use electricity for? Where does it come from? How does it get into our houses?
I have three words for you: playdough conducts electricity. The Thomas lab at the University of St. Thomas is developing squishy circuits as a classroom activity.
