Hey all you room moms out there, we’ve put together a perfect Halloween classroom party for you. This is a four part series and today is station #1: science. We’ve included some spooky fun experiments to do: ghostly goo, magic popcorn potion, wizard & muggles, and the amazing un-poppable balloon.

The four stations are set up to run simultaneously, rotate after about 10 minutes, and accommodate six to eight kids. For an average school class that’s 8 (kids) x 4 (stations) = 32 kids. The science station works best with 2 helpers to keep things running smoothly. One helper can be doing the experiment with the kids while the other one is washing things up and prepping for the next rotation.

This classroom party could also work at home or as part of another Halloween party.

Experiment: Ghostly Goo.

Supplies: 2 parts cornstarch to 1 part water, a bowl, a whisk or spoon

Have the children help you mix the cornstarch and water together in a bowl with the whisk or spoon. Show them how the mixture is both a solid and a liquid. If you press firmly on the mixture it’s a solid, if you try to pick it up it’s a liquid. This can get a little messy. If you do this experiment make sure you have a sink accessible for the kids to wash their hands in.

Experiment: Magic Popcorn Potion.

Supplies: clear soda pop, water, popcorn kernels, two see through containers

Have two clear containers with popcorn kernels in the bottom. Pour water into one container and see the kernels stay at the bottom. Pour soda into the other container and watch the kernels rise to the top. If you use a taller container than the one pictured it will take even longer for the kernels to rise to the top, extending the fun.

Experiment: Wizards & Muggles.

Supplies: 6-8 spoons (one per kid), 6-8 clear cups (one per kid), food coloring, baking soda, water, distilled vinegar, a tray or cookie sheet for under the cups

Put a drop of food coloring onto each spoon.  Cover the food coloring with baking soda. Fill all but one of the glasses halfway with water. Fill the last glass halfway with distilled vinegar. To contain the overflow of the baking soda mixture, place all of the cups onto a cookie sheet. Each child stirs their spoonful of baking soda into a cup. The children with the colored water are muggles and the child with the fizzy concoction is a wizard.

Experiment: The Amazing Un-poppable Balloon.

Supplies: a balloon (with polka dots or a pattern is best), a long pin, clear tape

Blow up a balloon and tie it so the air won’t escape. If your balloon has polka dots or another pattern on it, hide a small piece of clear tape on a bit of the pattern to disguise the tape. If you have a plain balloon, hide a small piece of tape where the kids won’t see it. With the children watching, carefully poke the long pin into the piece of tape and it won’t pop. Amazing.

You could also include some objects at the table for the kids to look at and feel. We have googly glasses for the kids to wear at this station, a black emu egg for them to touch, some eyeball candies, test tube vials with snakes and bugs, and plastic mice.

  1. The ghostly goo’s scientific name is non-newtonian fluid. Google it and see people walking on it!

  4. LOVE that you’re doing this! I’m in charge of my son’s 1st grade class Halloween party and I have a few ideas but could really use some more inspiration as this is my first time. Thanks! Looking forward to more great ideas.

  5. Thanks, Brittany! Great ideas. I’m going to send this to my niece. She’s a kindergarten teacher in Pennsylvania. She may be looking for some ideas for her class for Halloween!

  7. What’s the point if you don’t explain the science behind it. You are missing the whole point of demonstrating science to kids.

  8. so in love with this!!! eager to see the rest! yay!

  9. Rebecca–After each experiment you could definitely explain the science the behind it. Since this is a fast paced party that relies heavily on parent volunteers, we tried to make it as simple as possible for them. But if you were doing this at home I think it would be an excellent opportunity to teach your kids about the science behind these “magic” tricks. Thanks for you comment and for keeping me on my toes :]

  10. Thanks so much. Your Halloween ideas were a hit with my daughter’s joy school class and with my older daughter’s kindergarten class. We just chose the activities that were most appropriate for each age. All the kids had so much fun!

  11. Great ideas! My daughters both have Oct. birthdays and I am always looking for fun activities. We made ghostly goo. It was a little messy, but they had great fun! We did it at school as well and had all of the supplies that we needed.

  12. What wonderful ideas! I’m going to use these for our little family Halloween party. Thanks!

  13. Where did you find the cool glass beakers?

    Janet White    Saturday, March 3, 2012
  14. Hi Janet White–I can’t remember where the glass beaker is from, off the top of my head. But you can check through the Mad Scientist posts. The info might be listed there as we used the beakers originally at that party. http://onecharmingparty.com/category/mad-scientist-party/ xo

  15. Those are not beakers, they are Erlenmeyer flasks. You can find them at any science supply store such as Flinn Scientific (online).

  16. Another experiment I do is:
    I tell my students I found ghost poo on my yard last night. I did not see the ghosts but saw the poo. Then I give them the “poo” I collected and put it on their desks. They each have a small cup of water. They put the poo in the water and sure enough it disappears!! The poo is the recycled peanuts for packing. Only the recycled peanuts will dissolve. They really think it is magic.

    I also do a demonstration using dry ice. I tell them NOT to do this themselves or without an adult. But I show them dry ice and I use heavy gloves and tell them it will be so cold it will burn like licking an ice cube. Just be sure they understand they can not touch it.
    I will put a small piece of dry ice in my aluminum bowl and it makes screeching Halloween sounds. Then put that same piece of dry ice into a quart jar of warm water. It gives off that smokey fog. Then I add more “water” ( it is water with some drops of soap in it) and then the solution bubbles over the quart jar. Or you can just use straight soap and call it magic potion. I get ohs and ahs. If you want you can let the students touch the bubbles. They love to see the bubbles are cold. IF you want to do a bit more add glycerin in it and the bubble will stay longer and you can hold them in your hand.
