Let’s have some, and fill this October with fun Halloween science activities for kids, and parents, of all ages. We’ll be doing a number of these as potions to go along with our Wizards and Wands curriculum which I have conveniently planned to do in October. Especially the invisible writing below.

Some of these activities might be better for after Halloween if you don’t want to buy an extra pumpkin or two, and just plan to use your Halloween pumpkins.
