Spooky Science: 10 Experiments for Halloween

We’re raising 3 geeky girls around here.

They watch Doctor Who. They read maps for fun. They watch science shows on weekends. So, I’m always looking for ideas to give them the science they crave with the fun kids love. Enter home science experiments.

The girls love their annual science fair, especially when we get to play with candy, and Halloween is the perfect time to do a little more experimenting.

With just a few basic ingredients at home, the kids can explore the world of science with a spooky twist.

Here are 10 fun projects for October:

  • Pumpkin Investigation 1 of 10
    This is a great experiment for young children to do before you decorate your pumpkins. Find out if pumpkins sink or float, hypothesize about the number of seeds, take measurements — kids will love to explore and learn about the pumpkins.
