These 6 science videos tie in wonderfully with Halloween, and for the month of October they are free access for everyone.
Paint a Haunted Pumpkin that bleeds when you cut the painting. Look at the skeleton decorations in your classroom to see if they were right or left handed. Learn all about Pumpkin Guts. Make some slime or a screamer for some nice sound effects, and then learn how hard you will have to work to burn off all of the Calories from that Halloween candy.
With thousands of pages, it can be a challenge to find exactly the science you want.
