I remember a time when Halloween was nothing more than dressing up and running from house to house in search of the greatest candy bars. Fast-forward to 2008 and Halloween is a big deal… elaborate costumes, parties galore and merchandising second only to Christmas. Oh, did I mention that it’s a dream come true for the highly-motivated, somewhat neurotic science teacher who can’t wait to make things glow, ooze, pop, scream and gross out everyone who is willing to participate.

If you’re one of these teachers, please keep reading (because I need your help). This year, we’re compiling a list of the best Halloween Science Demos… so far. You’ll find some of my favorites in the list below, but this is just the starting point. I want to know your best Halloween Science Demos.

Just post a comment below and share what makes your students (or children) scream with excitement!

Hats off to Martha Stewart for job well done on her glow-in-the-dark pumpkins (okay, she called them funkins featured on October 26, 2007, on her television show. Our Media Product Coordinator, Brian Firooz, worked with the segment producer for several weeks to create a very cool effect using our Glow Powder and a little Martha Stewart creativity. The end result was a very cool glow-in-the-dark effect that was enhanced even more by using a black light.

The crew from Modern Marvels on the History Channel visited our science lab back in July to play with some really cold science experiments. In other words, the liquid nitrogen was flowing and the onions were exploding! Mark your calendars… Modern Marvels: Deep Freeze will officially be airing on the History Channel on Tuesday, September 25th at 8pm EST.

I love Halloween. One of my favorite activities is to “carve” pumpkins using a simple reation inside the fruit. First, you carve the face then carefully replace pieces. After creating a reaction by generating a gas inside and igniting it (ask your local chemistry teacher for the details) the face pieces are blown off with a small explosion.

Halloween is more than 100 days away and I just couldn’t wait. So I initiated the new weather anchor at the local Denver television station by introducing her to carving watermelons. The problem was, we didn’t really carve the watermelon, it exploded. Watch the Video to see how we skipped right over the carving and went straight to exploding.

Jack is 8 years old and likes to perform (he must get that from his Mom). Three years ago, the owners of Frog Street Press invited Jack to accompany me to their amazing summer conference for teachers called SPLASH. I helped Jack perform his first magic trick in front of a large audience (about 1,200 teachers) and that’s all it took. The Frog Street Press people were kind enough to invite us back this July, and Jack was ready to hit center stage. Jack’s routine is an original twist on a classic magic trick you might have seen performed by another magician using pom-pom balls. The audience in this video consisted of almost 1,700 early childhood educators (primarily pre-K through 2nd grade). Here’s Jack…
