So you’ve got Skittles, candy bars, M&Ms, candy corn, Peeps, lollipops, and so much more in a big plastic bucket, don’t you? I bet you are looking at it going whoa, that’s a whole lot of candy. Particularly, a whole lot of candy you don’t want the kids to eat. Believe me when I say we eat our share, but we also enjoy some Halloween candy science activities and STEM projects too. Simple science and STEM for kids!

HALLOWEEN CANDY SCIENCE ACTIVITIES & STEM

Here we love all types of STEM and Science Experiments, candy or no candy. Halloween is the perfect time for science activities and we had a blast this holiday season. The fun isn’t over yet! Check out all that candy you have.

We had a super successful night of trick or treating, at least 100 pieces of good stuff. We fully checked our load and my son chose to forgo the Great Pumpkin this year. I think his stash was to appealing. Our neighbors give out good stuff.

I brought together a list of ideas to use with some of the specific types of candy you probably have in your bucket. If you don’t have these, try your own versions of our Halloween candy science activities. Though some of these are classics and definitely should be tried at least once.

Click on the links in orange below to learn more about the set up of each candy science experiment for that type of candy. We all have a favorite candy around here. What’s yours? Can you turn it into a science experiment too.

MAKE PEEPS SLIME {TASTE SAFE}

MINI CANDY BARS AND 5 SENSES TASTE TESTING

Did you notice how these mini candy bars all kind of look alike. Snickers, Milky Way, 3 Musketeers…. Set up a lab for testing out these candy bars and record results.

CLASSIC SKITTLES ACTIVITY

This is great fun for kids. You have to see the end result.

M&Ms SCIENCE

Have you heard about the floating M? I bet you have a package of these tasty treats to find out.

DISSOLVING CANDY SCIENCE

We set up a tray to check out which candy dissolves the fastest in 3 different liquids. We used water, vinegar, and oil. Make sure you have three of each type of candy so the experiment is complete. Take a look at the results every so often. Older kids can take notes and use timers.

PEEPS & CANDY CORN

Dissolving Peeps and Candy Corn, Growing Peeps, Candy Corn oobleck, and Candy Corn Structures. A great way to use up candy you don’t want to eat too much of right!
