The Turn of the Screw

Science Fair Project Idea

Scientific Method

How much force is required to advance a lag bolt (large wood screw with a hex-shaped head) into a piece of wood? You can measure the force by using a spring scale attached to the handle of ratchet. Pull on the spring scale until the bolt starts to turn, and note the required force from the spring scale. There are many potential experiments you could try. Think about answering the following questions: How does the force change as the bolt advances deeper into the wood? Why? How does the… Read more

There's a Machine in My Toy Box!

Science Fair Project Idea

Scientific Method

"What?! Many of my toys are also machines?" That's right—simple machines! Simple machines are everywhere! Under your feet when you climb stairs, in your hand when you use a utensil to eat your dinner, even in your arm when you throw a ball. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple machine) of your toy box! Read more

Time is Money

Science Fair Project Idea

Scientific Method

How many times have you heard from your parents: "Clean up your room!" or "Don't forget to unload the dishwasher!" By applying principles of industrial engineering and time management, you can speed through your chores and have more time to kick back and relax. Read more

Understand Shock Levels and Packaging Principles

Science Fair Project Idea

Scientific Method

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping—you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is important for protecting the things we buy as they make their way from the factory to our homes. How much shock force is produced when a box gets dropped accidentally? What kinds of materials work best to protect products from damage? This project can show you… Read more

What's the Best Way to Disable a Drone?

Science Fair Project Idea

Engineering Design Process

Drones are small, fast, and maneuverable - this can make them very hard to knock down! Check out this Mark Rober video where he explores both how professional defense companies and some backyard YouTube engineers tackle the problem of knocking drones out of the sky. Can you take this engineering challenge on yourself? What methods can you devise to take down a drone? Which one works the best? Drones can be expensive, and you probably do not want to risk damaging a $1,000 drone for your science… Read more

What’s Your Ideal Walking Speed?

Science Fair Project Idea

Scientific Method

Walking may seem simple, but it is actually a carefully coordinated process involving balance, rhythm, and efficiency. The way we walk—our gait—changes depending on speed. At slower speeds, people tend to take shorter, more careful steps. At faster speeds, stride length usually increases and step frequency (cadence) rises to keep up. Biomechanics researchers study these patterns to understand how speed influences gait mechanics and stability, since walking is one of the most… Read more

You Nailed It! Hammering Force for Different Types of Wood

Science Fair Project Idea

Scientific Method

How much force does it take to drive a nail through different types of wood? In this project you'll build a simple test apparatus to swing a hammer reproducibly so you can find out. Read more
