Science Fair Project Idea

Scientific Method

Do you wish that you had duck feet? Aside from being a fun Dr. Seuss story, there is a lot you can learn about hydrodynamics by looking at the feet of birds. How are the feet of birds that swim unique? Find out in this experiment. Read more

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

The Tree of Life – II (advanced)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use Web-based computer… Read more

The Wagon Wheel Effect

Science Fair Project Idea

Scientific Method

Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Have you ever seen a video where it looked like a car's wheels were spinning backwards even though the car was driving forward? This is called the wagon wheel effect, named after old movies where it looked like wagon wheels were spinning backwards. Even though you cannot see the effect in person, it can show up in videos of spinning objects. Find out why in this project and make your own videos of the wagon wheel effect! Read more

The Wright Stuff: Using Kites to Study Aerodynamics

Science Fair Project Idea

Scientific Method

The Wright brothers used kites extensively to test their design ideas in the years leading up to their first successful airplane flight. With this science project, you'll learn about kite aerodynamics, and then come up with your own hypothesis about building or flying a kite. You can test your hypothesis two ways: with an online kite simulation program from NASA, and outdoors with the real thing! A great feature of this science project is that it has many possible variations, so you can decide… Read more

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster's loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal… Read more

Timing the Tides

Science Fair Project Idea

Scientific Method

Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during low tide. How much time does each zone spend out of water during a tidal cycle? Read more

Tireless Tides: Extracting Energy from Ocean Tides

Science Fair Project Idea

Scientific Method

Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within a short period of time. Hydropower energy is extracted from moving water, like ocean wave energy and tidal energy. In this energy science fair project, you will make a model of a tidal barrage (also known as a dam) and investigate how emptying the tidal barrage… Read more

To Infinity and Beyond: Plan a City of the Future with Sim City.

Science Fair Project Idea

Scientific Method

Everyday, people in your city or town walk to school, ride the bus and go to work, and go to the library to research their science fair projects. But what if the library was 20 miles away from your home? Would you go to the library? What if there were no police officers or fire stations in your city, or if they were located across town, away from where most people live? What if there were no movie theaters? What would you do with your friends? Many people really like living in cities in which… Read more
