Halloween is right around the corner, and no holiday is more perfect for STEM. With bubbling cauldrons and mysterious slime a regular part of this spooky day, we can’t help but share at least 5 of our favorite Halloween STEM ideas.
1.Make an edible potion. The possibilities with this one are endless, but almost all the best ones include dry ice. To keep it simple, just whip up some of your favorite punch or soda and add dry ice. Voila! Now you have a drink that is mysteriously bubbling over and disappearing and yet is completely harmless.
2.Make a graph out of your Halloween Candy. Although math doesn’t seem like the first think a kid may want to do when he gets home with a pillowcase full of candy, organizing candy into a graph is a fun way to compare candy with friends and family without even realizing that it’s math that you’re doing. All you have to do is find a flat large area that will fit all your candy and start organizing it by type. Make a column for Snickers, a column for Twix, etc. Make sure the different pieces of candy line up by row even if they are different sizes so the height will correspond to how many pieces you have. Did you get the most of your favorite type of candy? Who got the most in your family? After you’ve done a thorough statistical analysis, you may begin eating your candy.
3.Make slime. Nothing says Halloween STEM quite like a green non-Newtonian fluid. Look online for recipes or use your own favorite. For an extra spooky experiment, make glow in the dark slime.
4.Track the phases of the moon. Learn about what the different phases are called and make a sketch every day for a month of what the moon looks like. Just be sure to watch out for werewolves on October 24.
5.Make Self-Inflating Ghosts. All you need for this experiment is baking soda, vinegar, a plastic water bottle, a white balloon, and a sharpie. First draw a face on your balloon to make it look like a ghost, then fill it with about a tablespoon of baking soda. Fill the water bottle with about a half cup of vinegar, then attach the balloon to the top. Hold the balloon up so that the baking soda falls and reacts with the vinegar and watch your ghost come to life!
