Check in each week at Science Buddies this summer for our Awesome Summer Science Experiments series! Each week, we'll highlight a few activities for awesome science and engineering kids can do at home. We've got a whole summer of fun STEM themes lined up for kids of all ages — for free. This week: big-top science with awesome summer science experiments that tap into the spirit of the local fair, amusement park, or carnival.

Pyramid of bottles with a ball being thrown at it - Carnival STEM Week 9 of Awesome Summer Science with Science Buddies

Awesome Carnival STEM

Ready for backyard, amusement park fun with science? Step right up! From carnival games to marble roller coasters, funhouse mirrors, and bottle flipping, this week's Carnival STEM experiments bring the excitement home. Add in popcorn, homemade tickets, and some prizes scavenged from around the house for a fun summer carnival experience!

The activities in Week 9 of our Awesome Summer Science Experiments series feature STEM experiments that focus on the physics of balancing, mirrors and reflection, trajectory and momentum, centripetal force, and potential and kinetic energy.

EXPERIMENT: Carnival STEM

Mirror Distortion

Have you ever looked in a mirror that made you look taller or shorter or bigger or smaller than you are? These mirrors can be fascinating, but what's the secret? Make your own funhouse mirror and explore the wacky world of curved mirrors. What happens when you look at something in a curved mirror compared to a flat one? What's the difference between concave and convex mirrors?

A Balancing Act

Have you ever seen a clown balancing a teetering tower of objects on a pole? Explore how balancing works with marshmallows and wooden sticks. What's the craziest configuration of sticks and marshmallows you can balance?

Knock Over the Bottles

Throwing balls at a stack of bottles is a classic carnival game! Explore the science behind knocking over the bottles by setting up your own backyard game. What does the center of mass have to do with how easy or hard it is to win?

Make a Centripetal Force Generator

Centripetal force helps keep you in your seat on amusement park rides that swing you in a circle. Explore the push and pull of centripetal force with a homemade centripetal force generator, colored gelatin, and a marble. What happens to the marble when the swinging begins?

Loop-the-loop with a Marble Roller Coaster

Roller coaster loops are part of the thrill of the ride, but it takes science to make a roller coaster loop work! Build your own marble roller coaster from foam tubing and see if you can add a loop and still have the marble make it from start to finish. How high will your coaster need to start for a marble to make it around the loop? Can you add a second loop?

Bottle Flipping

Have you tried tossing a bottle to see if you can make it land standing up? It's exciting when it works, but what's the secret? Explore bottle flipping to find out if how much water is inside makes a difference. Can you find the just-right amount for your bottle flipping technique?

SCIENCE KIT: Raspberry Pi Projects Kit

Carnival-style game made from a wire and coded so that it buzzes if you touch the wire

How steady are your hands? With the Raspberry Pi Projects Kit, kids can create and code their own interactive buzzer game and challenge friends and family to see who can complete the game fastest without triggering the buzzer! The Construct a Carnival Buzzer Game with a Raspberry Pi project is one of 8 guided activities kids can do with the Raspberry Pi Projects Kit. After finishing the progressive learning series of activities, kids can continue coding and creating interactive projects with Raspberry Pi using the drag-and-drop Scratch interface or move on to exploring Python.
