Science Fair Project Idea

Scientific Method

What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

Find the Best Place to Put a Solar Panel

Science Fair Project Idea

Scientific Method

Imagine trying to put a solar panel on your roof or outside your home to generate clean, renewable energy. Where would you put it so it generates as much power as possible throughout the day? What direction should it face? Is there a way to take measurements to find the best location before you install the panel? In this project, you will use a tiny programmable device called a micro:bit to record light data and find the best place to put your panel. Read more

How Antacids Relieve Heartburn

Science Fair Project Idea

Scientific Method

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

Gigantic, Invisible Triangles: Measuring Height (or Altitude) with an Inclinometer

Science Fair Project Idea

Scientific Method

If you've ever wondered how tall that bridge is, or how high your kite was, then this could be a good project for you. You'll learn how you can use the mathematics of right triangles to measure the height of an object with two measurements that you can make on the ground. Read more

Agrivoltaics: What Crops Grow Best Under Solar Panels?

Science Fair Project Idea

Scientific Method

We need farms for food, and we need solar panels for renewable energy. What if we could combine the two? Find out if certain crops can grow well under the partial shade of solar panels in this agrivoltaics science project. (Note: you do not need access to real solar panels to do this project. Any source of shade will work.) Read more

Hit the Slopes: Build Your Own Ski Lift

Science Fair Project Idea

Engineering Design Process

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

What Modern Microbes Could Survive on Early Earth?

Science Fair Project Idea

Scientific Method

Have you ever wondered how life began on Earth? Or how life could get started on other planets? To help us better understand how life began, many scientists try to figure out what it would have been like to live on early Earth. In this science project, you will try to grow microscopic life that could have survived some of the harsh conditions of early Earth! Read more

Pedigree Analysis: A Family Tree of Traits

Science Fair Project Idea

Scientific Method

Some characteristics, like the shape of your hairline or whether your earlobes are attached or detached, are inherited from your parents. In this science project you will see how writing these characteristics onto a family tree can help you determine how they are inherited 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

Does How You Hold Your Guitar Affect the Sound?

Science Fair Project Idea

Scientific Method

What do a guitar, a piano, a harp and a violin have in common? Turns out a couple of things, including a soundboard. All stringed instruments use a soundboard to amplify (greatly increase) the volume of the sound coming from vibrations of the strings. The soundboard is positioned so that it gathers the sound vibrations coming from the strings and then retransmits them at an even greater volume when it begins to vibrate. Soundboards are common in the world of musical instruments, but they can… Read more
