The Taylor Swift Challenge

Science Fair Project Idea

Scientific Method

Taylor Swift famously got in shape for her three-hour-long Eras Tour concerts by singing all 40+ songs...while running on a treadmill! Have you ever tried running while singing at the top of your lungs? How hard do you think it is? In this science project you will measure the impact talking and singing have on a group of volunteer runners. Is anyone in better shape than Taylor Swift? Read more

Separating Butter with a Salad Spinner Centrifuge

Science Fair Project Idea

Scientific Method

Imagine that you could make an important piece of laboratory equipment in your kitchen. With this science project idea, you can! You will create your own centrifuge out of a salad spinner and some putty. In science labs, centrifuges are used to separate different liquids and/or solids from each other. You can load your homemade centrifuge with samples and see how they separate. What do you think happens to melted butter in a centrifuge? Read more

Yuck, What Happened to My Apple? How Food Wrappings Affect Spoilage

Science Fair Project Idea

Scientific Method

Have you ever eaten half an apple and saved the other half for later, only to find that, by time you were ready to eat it, the apple did not look as tasty anymore? It may have turned brown and shriveled, and, if left out long enough, it may have spoiled. Do you think you could have prevented the other half from spoiling, or made it spoil less, if you had stored it differently, such as in the refrigerator in a food wrapping? In this cooking and food science project, you will investigate which… Read more

Let's Go Fly a Kite!

Science Fair Project Idea

Scientific Method

Kites have been a source of entertainment for centuries for kids from cultures around the world. In this science project you will have a chance to build your very own kite, a simple sled kite. Then you will use it to investigate how kites fly. Will you find out the best way to fly your kite? Read more

Bug Vacuums: Sucking up Biodiversity

Science Fair Project Idea

Scientific Method

Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Motion Mania: Applying Physics to Hula-Hooping

Science Fair Project Idea

Scientific Method

Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop expert. If… 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

Which Materials Can Catch a Bubble?

Science Fair Project Idea

Scientific Method

Can you catch a bubble with your hands? What if you use another material, like a piece of paper or aluminum foil? Try this science project to find out which materials can catch a bubble without popping it. Read more

Sprouting Sweet Potatoes Slips

Science Fair Project Idea

Scientific Method

Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants. Read more

Make Your Own Hot Air Balloon

Science Fair Project Idea

Scientific Method

Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.
