Spooktacular Halloween Science Projects

Science Buddies has great hands-on science projects and activities that tie in with spooky Halloween fun. Whether you are looking for a project related to candy or costumes or Halloween-inspired electronics and robotics, we have suggestions for student STEM that can help turn an ordinary October day in science class into something spooktacular!

Halloween Science for K-12 Students

To spark Halloween-themed science experimentation or discussion, see the following projects and activities:

• Blood Clotting to the Rescue: How to Stop Too Much Blood from Flowing: students learn about human biology and coagulation while getting hands-on using spherification to make "balls" that stand in for blood in the project.
• Build a Brushbot: use assorted chunky cleaning brushes to explore basic robotics with a brush head vibrobot. (See our Halloween-inspired student example.)
• Build a Gumdrop Geodesic Dome: explore math, science, and engineering by building a geodesic dome from candies and toothpicks. (See our Halloween spin on this project with candy corn gum drops.)
• Electric Play Dough Project 1: Make Your Play Dough Light Up & Buzz!: experiment with introductory circuits using insulating and conducting doughs and LEDs. (See Electronics and Play Dough: Fun, Tactile Family Science for our Halloween spin on this introductory electronics project.)
• Explore Glow-in-the-Dark Water! : use tonic water, bleach, and a black light to make the tonic water glow.
• Exploring Mummification with Hot Dogs: what can you learn about ancient Egypt and science from a hot dot? The end result may be creepy and gross, but kids love it! (Note: this project takes several days of wait-time to complete, but students will love the cool factor of knowing that something is mummifying in a box somewhere in the room!)
• How Bright Is Your Glow Stick? Measure It!: match up popular glow sticks with a chemistry and electronics project by building a simple device to measure the intensity of light produced by glow sticks and other glow-in-the-dark materials.
• Make Popping Boba Balls Out of Your Drinks: depending on the color of the beverage used, juice balls can easily be part of a brains- or guts-inspired Halloween treat... that they can eat! (See our hands-on test for an up-close look at the juice balls experiment.)
• LED Dance Glove: Get the Party Started with Your Own Interactive Light Show: create a glove (or other piece of clothing) with a wearable light-up circuit for science they can really see in the dark! (See our hands-on write-up for an example of a light-up skeleton cat patch. This science project makes for a great, creative, hands-on science experiment. Students walk away in the end with something they can wear.)
• Make an Alka-Seltzer Powered Lava Lamp: make a fun non-electric lava lamp with the help of the fizzing power of Alka-Seltzer®.
• How to Turn a Potato Into a Battery: explore battery basics using potatoes or other vegetables in this introductory electronics project. (See our Halloween-inspired pumpkin and squash battery experiments.)
