Build a Water Clock to Show the Drip, Drip, Drip of Time

Science Fair Project Idea

Scientific Method

What are some of the ways we keep track of time? We have alarm clocks, wristwatches, and cell-phone clocks, to name a few. Just a few hundred years ago, our ancestors did not have any of these conveniences, yet they found ways to tell time. How? By using devices such as water clocks. In this science project, you will follow in the footsteps of early engineers and build a water clock that tracks time for three hours. Read more

Do you play or watch a sport where you use something (other than your hands or feet) to hit a ball? Golf, baseball, tennis, hockey—there are many different sports where players use something to hit a ball or a puck. In this activity you will design, build, and test your own sports equipment made from recycled materials. Read more

Building a Model Hydraulic Knuckle Crane

Science Fair Project Idea

Scientific Method

A ship is a busy place. When out to sea, naval, research, and fishing vessels pull or push heavy loads, like research equipment and crab pots, into and out of the water. But equipment and pots can weigh hundreds of pounds. So how does a ship's crew lift loads efficiently and accurately? With a hydraulic knuckle crane, of course. But what is hydraulics and why does hydraulics make certain tasks easier? Hydraulics is the study of liquids and their mechanical properties: how they move, resist… Read more

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

Cricket Wicket Knockdown Challenge

Science Fair Project Idea

Scientific Method

In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Teachers, lesson plan versions of this challenge are also available. Read more

Did you know that gears are all around you? You can find them in wind-up toys, bicycles, carousels, cars and trucks, cranes, drills, wind turbines, analog watches, and so forth! If you've looked closely at a moving bicycle, you have seen gears at work. Are you curious about their purpose? In this activity you will use candy to make gears and explore why they are so versatile. Read more

Gears-Go-Round!

Science Fair Project Idea

Scientific Method

Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment. Read more

Have you ever used a coin-sorting machine to separate pennies, nickels, dimes, and quarters? When you need to separate things that are all mixed together, using a machine can be much faster than picking them apart by hand. In this project you will build a machine that can automatically separate two different size marbles, powered by nothing but gravity. Read more
