Halloween Science Spooky Fun for Kids

Halloween is pretty much the coolest time of year to learn science. I mean, when else can you throw a party where the biggest wow factor happens because of chemistry or physics? Because that’s exactly what happens when you make things glow in the dark, change color, make scary sounds and explode! Here are some of my favorite Halloween science for fun at home or in the classroom. This post contains affiliate links.

The Screaming Cup

This spooky cup is great for Halloween night entertainment or perfect for creepy sounds as guests arrive to your Halloween party. You’ll have to judge the age of your little monsters for this one. It’s SUPER easy to put together and will last for years to come. Just add more rosin to your string.

Use the screaming cup to talk about vibrations. Try making a variation with different size cups and different size strings to see what makes the spookies sound! Your preschoolers will love this one. Expect to have to set a time limit on how many screams come from this fun experiment!

Glow In The Dark Jack-o’-Lantern

Making a Jack-o’-lantern is a tradition on our house. We make it a family night event and have a blast getting our hands dirty. I’m also a huge fan of all things glow in the dark. Halloween is the perfect time to experiment with glow in the dark powder! This year we are going to make our Jack-o-Lanterns glow in the dark for a fun Halloween party experience.
