Model Water Flow in Rivers

Science Fair Project Idea

Scientific Method

Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape. Read more

Can Aloe Juice Save Your Berries from Mold?

Science Fair Project Idea

Scientific Method

Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry—yuck! Companies look for natural, plant-based ways to protect the berries from mold when they are in the store, waiting for you to purchase them. Would washing them in aloe vera juice protect strawberries from mold? Do this project and find out! Read more

Centripetal Force

Science Fair Project Idea

Scientific Method

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Abracadabra! Levitating with Eddy Currents!

Science Fair Project Idea

Scientific Method

Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more

Rubbing Up Against Static Electricity

Science Fair Project Idea

Scientific Method

A tried and true balloon activity is to rub a balloon on your head to make your hair stand up. How does the rubbing build up static electricity? Do this experiment to see if the number of rubs makes a difference. Read more

Shaking for Butter

Science Fair Project Idea

Scientific Method

Hot pancakes with butter running down the sides, freshly baked biscuits and pastries with butter, hot flaky potatoes with melted butter. Yum! It seems like everything tastes better when you add butter. But what is butter and how is it made? In this food science fair project, you will find out, and you will test different conditions for making butter and determine the best method. Read more

Eeew, Dog Breath! Does Active Play Take Your Dog's Breath Away?

Science Fair Project Idea

Scientific Method

When you're chasing after your dog, do you ever stop and say, "Wait, I have to catch my breath!"? Do you think that there are times when your dog feels like that, too? Does your dog's respiration rate change when you two are playing active games together? Try this playful science project to find out! Read more

What Makes the Rings of Saturn?

Science Fair Project Idea

Scientific Method

Saturn is a unique planet because of the many beautiful rings surrounding it. How are all of those rings made? Why is each ring unique? 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

Jumping For Geodes: Can You Tell the Inside from the Outside?

Science Fair Project Idea

Scientific Method

Have you ever heard the expression, "You can't judge a book by its cover"? What do you think that means? That a book with a very plain cover might have a very exciting and interesting story inside? Well, in this geology science project, you'll see if the same expression holds true for a rock, but not just any old rock, a special type of rock called a geode, which looks rather plain and ordinary on the outside, but inside can hold crystals and beautiful colors! You'll discover if the texture or… Read more
