The Orlando Science Center wants to shed some light on how you can incorporate STEM learning concepts into your Halloween activities!

Learn about sensory slimes, how to make oobleck dance and the inner workings of cardboard automatas in this video. Then, try these spooktacular projects at home using the instructions below.

 

 

Spooky Sensory Slimes

This sensory activity is fun for all ages, but especially great for our littlest learners in Pre-K.

Ingredients for basic slime: 

  • 1 quarter cup of Elmer’s Glue
  • 1 Tablespoon of liquid starch
  • Food coloring, sparkles and toys (optional)

To incorporate STEM concepts, make this project all about scientific inquiry! Have your child ask questions and make predictions and comparisons.

Some good questions to ask include:

  • How is the slime going to act?
  • What will happen if we throw it on the floor?
  • Can you stretch it?

 

Dancing Oobleck

Oobleck, is a non-newtonian substance. Cool name, right? Well, you might be wondering what it means!

Oobleck has properties of both liquids and solids. You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or hit it hard, it will feel solid. We made our oobleck dance by putting it on a subwoofer (remember to cover yours with plastic) and playing a song with a low frequency, a.k.a a bass tone.

Ingredients for oobleck: 

  • 1 part water
  • 1.5 to 2 parts cornstarch
  • Small amount of food coloring (optional)

 

Cardboard Automata

This is a really fun Maker activity that you can try at home! Use this project to explore simple machines, specifically wheels and axles. Use your critical thinking skills and creativity to make your project move. Check out how you can create your own cardboard automata in the slideshow below.

 

Thank you for joining us for Spooky Science Month! We hope you have a ghoulishly good time trying these experiments at home!
