Halloween is right around the corner. Your students are already dreaming of costumes and candy. Here’s how to harness that magical energy into actual learning instead of just surviving until the bell rings.
Start Here: The Science Behind Magic
Ask your students why a baking soda and vinegar “witch’s brew” bubbles over. Write down what they say.
Most will tell you the ingredients “hate each other” or it’s just “magic.”
Here’s the fact that makes them pay attention: It’s not magic, it’s destruction.
Tell a kid they aren’t casting a spell; they are literally destroying two normal kitchen items to create an entirely new invisible gas. They just created a ghost (carbon dioxide). Watch their eyes light up.
How to Make a Pumpkin Ooze DIY Activity
Are you looking for ways to add more spooky halloween fun to your science lessons? Learners get the chance to create a pumpkin that oozes and bubbles all by creating a chemical reaction with a few simple steps. Check out How to Make a Pumpkin Ooze with @teachmesomethingood,Teacher Taylor Blair.

Grades K-2: Slime and Spooky States
They just want to touch gooey things and call it monster boogers. We need them to understand solids versus liquids. The slime is the hook; the state of matter is the standard.

Grades 3-5: Potions and Changes
At this age, they think any bubbling liquid is a magic potion. You have to break the illusion and show them the mechanics of what’s actually happening when things change state or react.

Grades 6-8: Exothermic Reactions
Middle schoolers act like they’re too cool for Halloween, but they aren’t too cool for things that smoke, bubble, or heat up. Show them an exothermic reaction that looks like zombie blood, and they’re ready to start learning.

The “I Have 20 Minutes Before the Costume Parade” K-5 Version
No time to prep? Here’s exactly what to do:
Minutes 1-5: Put a picture of slime on the board. Ask them to vote: Is it a solid or a liquid? Make them defend their answers.
Minutes 6-15: Play the Solids, Liquids, & Gases (K-2) or Properties of Matter (3-5) video.
Minutes 16-20: Do the digital exit ticket to prove they actually learned the standard. Tack on a DIY activity at the end of the day, because let’s be honest, DIY’s make science even better.
Halloween is more than just a classroom management hurdle. It’s the easiest, most built-in hook of the year for physical science. Embrace the spooky science fun for your next science lesson.
