Science Fair Project Idea

Scientific Method

There is a bewildering selection of different golf balls to choose from for playing the game. Some less expensive, some more expensive, all with different claims for the advantages they will bring to your game. This project can help you determine which type of golf ball is right for you. Read more

The Power of Suggestion

Science Fair Project Idea

Scientific Method

Can an authority figure make someone question their own memory? How reliable is eyewitness information? This project looks into these questions. You'll need a poster-sized image that includes many faces, and a volunteers to act as "eyewitnesses." The volunteers are tested individually. The instructions are that they have one minute to examine the poster, and then a fixed amount of time (e.g., 5 minutes) to write down brief, accurate descriptions of all the faces they can remember. They'll… Read more

Alternative Sources for Paper Fiber

Science Fair Project Idea

Scientific Method

If you're interested in arts and crafts, you might like this project. It uses several alternative, renewable sources of fiber to make paper, and compares the resulting papers for strength and writing quality. Read more

One Bad Apple Spoils the Whole Bunch: An Experiment on the Plant Hormone Ethylene

Science Fair Project Idea

Scientific Method

We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true! This experiment will investigate the role of ethylene in the process of fruit ripening. Read more

It's Hard Work to Work Harden! Learn How to Make Metals Stronger

Science Fair Project Idea

Scientific Method

It's easy to forget that metals are everywhere and in nearly everything. They are a part of our lives in so many ways that we hardly notice them. But just stop and think about it. We use metal spoons to eat and cook our food. Cars, bikes, and planes are composed of metals. Metals are in our furniture and part of your school supplies. Some people even have metal in the dental work in their mouths. Their strength and dependence is obviously very important. But what are metals? In this science… Read more

Building Banjos

Science Fair Project Idea

Scientific Method

The banjo's roots trace all the way over to Africa. The unique sound that a banjo makes depends, in part, on the resonator. The purpose of the resonator is to amplify and project the sound that is made by strumming and plucking the strings. In this music science fair project, you will experiment with a resonator on a banjo and see if you can hear the difference in sound. Read more

Make a Glitter Surprise Package

Science Fair Project Idea

Engineering Design Process

Have you ever seen a video of a glitter prank package? They usually show an unsuspecting person opening a package or a gift, only to be sprayed by a shower of glitter. Former NASA engineer Mark Rober got tired of thieves stealing packages off his porch, so he decided to build an elaborate decoy glitter package*, as he shows in this video. Mark's device involves a lot of custom software, electronics, and 3D printing, so might seem a little intimidating if you are new to engineering. The summary… Read more

Stair Master: Build an All-Terrain Robot

Science Fair Project Idea

Engineering Design Process

Have you ever tried to ride your bike up a flight of stairs? Vehicles with wheels are great at traveling on paved roads or flat ground, but when it comes to stairs or uneven ground in the woods, wheels are not always such a great option. Inspired by real-life all-terrain robots, in this engineering project you will design and build a LEGO® robot that can travel over bumpy ground, through your yard, or even up a stack of textbooks — and almost anything else you can think of!
