Stop the Train! Magnetic Brakes for a Maglev Train

Science Fair Project Idea

Scientific Method

Did you know that you can use magnets to build a train that floats above its tracks? In this project, you will also use magnets to make the train stop, preventing it from crashing into the end of the track. Will adding more magnets help the train stop sooner? Read more

Spread the Soap, Not the Germs

Science Fair Project Idea

Scientific Method

Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of. Read more

Solar-Powered Salt Removal

Science Fair Project Idea

Scientific Method

Have you ever thought about being stranded on a desert island? How would you find water to drink? What would you need to survive? In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun. Read more

Juice Box Geometry

Science Fair Project Idea

Scientific Method

Juice boxes are so convenient—just poke the straw in and sip away! But have you ever noticed that some juice boxes don't seem to have much juice, even when they have a lot of packaging? It might surprise you how much thought goes into the design and manufacturing of a juice box. Each manufacturer has carefully calculated how big each side should be to hold a certain amount of juice inside. In this science project, you will find out how different brands of juice measure up.

Make Your Own Markers

Science Fair Project Idea

Scientific Method

Do you ever wonder how markers are made? Where do all of those colors come from? Many of the colorful dyes we use come from plants. Could you create vibrant colored natural dyes? Could you turn these dyes into art supplies? You can! In this science project, become a scientist and engineer and make your own marker using homemade plant dye! Read more

Plants Are On The Move! A Study of Gravitropism

Science Fair Project Idea

Scientific Method

As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more

Suck It Up: Capillary Action of Water in Plants

Science Fair Project Idea

Scientific Method

Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more

Electric Play Dough Project 2: Rig Your Creations With Lots of Lights!

Science Fair Project Idea

Scientific Method

Have you tried our first electric play dough project, and now you are looking for more to do? Do you want to learn more about circuits and add even more lights? Check out this project for part 2 of our play dough circuits series! Read more

Coke® & Mentos® - Exploring Explosive Chemistry!

Science Fair Project Idea

Scientific Method

You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

How Well Do Disinfectants Work?

Science Fair Project Idea

Scientific Method

Germs are everywhere! We try and clean our home with disinfectants, but do we really get rid of all the germs? Find out with this "hands-on" experiment. Read more
