5 Halloween STEM Challenge Activities

Halloween STEM challenge activities are the perfect way to keep kids engaged all throughout October. The best part — there are so many connections to your science and other subject areas, you’ll be using every drop of your instructional minutes like a pro while your students proclaim you the best teacher ever! 🎃

If you’re a STEM Challenge enthusiast, you know any challenge can be used for any age with just a few modifications. If you’re new to the game — or just tired of doing all the heavy-lifting yourself — check out the video walk-throughs linked next to each challenge below as well as teaching resources for modifications for grades 2-8.

Here’s a very quick visual of each of the 5 Halloween STEM Challenge Activities in action:

If you hadn’t already picked up on it, I 😍 Halloween! I have an entire playlist of video walk-throughs on YouTube with the STEM Challenges you see below and others I think are a natural fit for Halloween. Check out the entire Halloween STEM Challenge playlist from YouTube if you’re looking for inspiration.

You’ll find the original video walk-throughs there as well as modifications to use in virtual environments (look for the pandemic era videos).

And there’s more where this came from! Over the years, I’ve continued to add to my Halloween STEM activities resources. You may want to check out this post where I’ve amassed 20 Epic Halloween STEM Activities, including the 5 mentioned below.


Here’s a quick description of 5 of my favorite Halloween STEM Challenge activities, plus links to their video walk-throughs and teaching resources for each one:

Halloween STEM Activity 1: Bone Bridge®

Bone Bridge®– students build a bridge for length, strength, or capacity. Connect it to your lessons on the skeletal system, bridges/transportation, and/or forces! Learn more in the video walk-through and the teaching resource.

Halloween STEM Activity 2: Wings Wanted

Wings Wanted — students design a new set of bat wings, with the goal being to achieve maximum flight distance and/or accuracy. It’s a paper airplane challenge with a twist! Learn more in the video walk-through and the teaching resource.

Halloween STEM Activity 3: Creature Catcher

Creature Catcher — students design a device to catch as many “creatures” as possible. While spider web designs come to mind, there are many ways to catch a creature. Let your students’ imagination and creativity shine by leaving the challenge open-ended. Learn more in the video walk-through and the teaching resource.

Halloween STEM Activity 4: Treat Toss

Treat Toss — students build a low-energy machine to toss treats without spreading germs. Build for maximum launch distance and/or target-accuracy. Perfect introduction to simple machines, particularly levers! Learn more in the video walk-through and the teaching resource.

Halloween STEM Activity 5: Ghosts in the Graveyard

Ghosts in the Graveyard — students create a ghost transporter that lifts cotton ball “ghosts” from the ground to the top of a pulley. Use grapes instead of ghosts if Halloween is a no-go at your school. Learn more in the video walk-through and the teaching resource.
