Simple Spooky STEM Activities to Scare Up Some Fun

Get into the Halloween spirit with these simple spooky STEM activities!

Halloween is one of our favorite holidays at the Orlando Science Center, so we’ve rounded up some of our favorite simple spooky STEM activities that you can do at home!

We’ve also included instructions on how to give some activities a special Halloween twist. From making the slimiest slime to exploring art with candy, find them all in one place below.

STEM Slime Time!

Our staff concocted the slimiest slime recipe for you to try at home! For glowing slime, use tonic water or highlighter water instead of regular water. Click here to make highlighter water!

Spooky Oobleck

Make an ooey-gooey mess with just two ingredients! Learn about the states of matter and viscosity, practice lab skills like measuring and mixing with this educational messy science experiment that's so fun, you won't even realize you're learning!

To make pumpkin oobleck, color the oobleck orange with paint or food coloring and add pumpkin-scented oil. Alternatively, you can mix a can of pumpkin puree in a pitcher of water and use it in place of the regular water.

Ectoplasm Detector

Have you ever wanted to make something glow under a blacklight? Let us teach you one of our favorite hacks, which you can turn into an Ectoplasm Detector!

Write or draw messages, then hide them in a dark place. Make the Ectoplasm Detector by following the instructions for your DIY Blacklight Hack then use your ectoplasm detector to find and reveal the ghostly messages!

Ghosts in the Graveyard

Have you ever wanted to make something glow under a blacklight? Let us teach you one of our favorite hacks, which you can turn into an Ectoplasm Detector!

Write or draw messages, then hide them in a dark place. Make the Ectoplasm Detector by following the instructions for your DIY Blacklight Hack then use your ectoplasm detector to find and reveal the ghostly messages!

Sweet Science

Trick or Treat! In this experiment, science is sweet! Use a little bit of candy to make Halloween pictures that swirl like magic, to explore chemistry, and to practice making predictions and observations.

How to Demonstrate Static Electricity and Shock Your Friends

Learn a phantom-tastic physics lesson while you learn how to demonstrate static electricity! 

How do you make a tissue dance? You put a little boo-gie in it!

Static electricity is electricity that doesn’t move. You’ve experienced static electricity if you’ve ever rubbed your feet on a carpet and then zapped a friend or sibling.

Let us teach you how to demonstrate static electricity, and put a little boogie in tissue paper ghosts to make them dance in this fun and simple science activity.

Materials you will need:

  • Tissue
  • Black marker
  • Scissors
  • Clear tape
  • A balloon
tissue paper, scissors, marker, tape, balloon- materials needed to demonstrate static electricity

Directions:

Step 1:

Carefully separate the layers of your tissue and pull them apart. We want our tissue paper to be very thin for this activity.

Step 2:

Draw ghosts on your tissue pieces then cut them out.

Step 3:

Tape the bottom of each ghost to your work surface with clear tape.

Step 4:

Blow up a balloon then rub it against your hair or against wool. A fluffy wool sweater or blanket will work!

  • While you work on your experiment,  ask your scientist some questions: 
    • Before you hold your balloon over the ghosts, ask your scientist what you think will happen. This called a hypothesis.
    • What happened when you rubbed the balloon against your hair or with wool?
    • What do you think would happen if we didn’t pull the tissue apart?

Step 5:

Hold your balloon 3-4 inches above your ghosts and move it around to make them rise up from the grave and dance!
*If nothing happens right away, try moving the balloon closer to the ghosts or rubbing the balloon again.

Take the experiment further:

  • How many ghosts can you lift up at once?
  • How far away can you hold the balloon from the ghosts and still make them move?
  • What happens if you use different thicknesses of paper? What about different types of paper? Why do you think some types and thicknesses of paper work better than others?

Learn more about static electricity

  • Electricity is a form of energy that powers our electronics like our TVs, computers, light bulbs, and more.

  • Static electricity is electricity that doesn’t move. You’ve experienced static electricity if you’ve ever rubbed your feet on a carpet and then zapped a friend or sibling, if you’ve ever zapped yourself touching a doorknob, or if you’ve ever seen lightening before.

  • Electricity is created by teeny tiny particles called protons and electrons. Protons are positively charged, while electrons are negatively charged. Just like magnets, opposites attract. So the positive protons and negative electrons attract each other!

  • When you rubbed the balloon with the cloth, you built up a negative charge on the balloon by adding electrons to it. Our little tissue paper ghosts are positive, so they were attracted to the balloon. This causes them to rise up!
