EXPERIMENT: Unicorn Science Experiments

Light-Up Unicorn Horn

With your own magical unicorn horn, you'll fit right in with the unicorn herd! Use copper tape and paper circuits to make your own headband with a light-up unicorn horn. You can make the headband as sparkly and magical as you want. When you take the headband off, unclip the battery from the circuit to turn the light off until you are ready to head out with your unicorn again. (For more paper circuit activities, see Paper Circuits Science Projects.)

Colorful Unicorn Slushies

What kind of snack can you feed your unicorn? Make a homemade slushy in your unicorn's favorite colors for a whimsical afternoon treat. As you freeze your slushy mixture, you will find out why salt is used in the freezing process.

Unicorn ArtBot

Unicorns can be artists, too! Turn a plastic cup into a unicorn artbot robot that draws in multiple colors of marker as it shuffles around on marker legs. This robot is an introductory-level robotics activity with a simple circuit. How many colors can you use? What shapes will the unicorn artbot draw?

Unicorn Snot

What happens when your unicorn sneezes? Make your own unicorn slime in magical colors for icky fun with science. You can even mix in a bit of sparkle! DIY Slime is easy to mix up, and with a bit of science, you can create a recipe with the properties you want.

Unicorn Trailer

If your unicorn is going on a journey or vacation with you, it can travel in style with a special unicorn trailer. Use the directions for the rubber-band car and customize the shape of the car to make a unique trailer or car for your unicorn.

Rainbow Candy

Making lollipops at home is fun, but when you want to make something extra special for your unicorn, try making these rainbow lollipops. Turn them just right in the light to reveal sparkly rainbows on the surface!

ASK: Questions

Use these questions to prompt conversation and reflection about the science behind the Pirate Science activities:

  • Why is it important to think about the "properties" you want a product to have? How is this related to science and engineering?
  • When building paper circuits, what is the role of the copper tape (or aluminum foil)? What does it mean for a circuit to be closed?
  • Does the color of food change how someone thinks it tastes? How can you use science to explore this question?
  • When making a balloon-powered car (or trailer), what difference does the size of the balloon make?
  • In a simple robot like the unicorn artbot, what makes the robot move?
