Use the Force! Push & Pull Robots With an Invisible Force

Science Fair Project Idea

Scientific Method

If you have seen any of the "Star Wars" movies, then you probably remember when Jedi knights like Luke Skywalker and Obi-Wan Kenobi used "The Force" to push, pull, and even throw objects — including some helpless battle droids. Have you ever wished you could do that in real life? In this robotics project, you will build and program a LEGO® robot that you can push and pull using an "invisible force" — almost like a real Jedi! We make no promise that you will be taking down the… Read more

Using a Digital Camera to Measure Skyglow

Science Fair Project Idea

Scientific Method

This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more

Using Daphnia to Monitor Water Toxicity

Science Fair Project Idea

Scientific Method

One way to test for the presence of toxic compounds in a water sample is a bioassay. In a bioassay, a living organism serves as a detector for toxins—the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay to monitor water quality. Many variations of this experiment are possible. Read more

Vibrobots are tiny robots powered by a vibrating motor, like the type found in cell phones. In this lesson plan, your students will learn about engineering design as they build their own vibrobots from craft materials. No previous experience with robots is required! Read more

NGSS Performance Expectations:

3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

What Color Are the Leaves Really Turning?

Science Fair Project Idea

Scientific Method

Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

What Makes a DNA Fingerprint Unique?

Science Fair Project Idea

Scientific Method

Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more

What Makes the Rings of Saturn?

Science Fair Project Idea

Scientific Method

Saturn is a unique planet because of the many beautiful rings surrounding it. How are all of those rings made? Why is each ring unique? Read more

Which Kind of Wood Burns Slower?

Science Fair Project Idea

Scientific Method

Do you ever go camping with your family and roast hot dogs and marshmallows over a campfire? If you want your campfire to burn long into the evening, what is the best wood to use? Do research on the necessary conditions/materials to sustain a fire and on the properties of different types of wood. Which properties do you think will be most important for determining how fast the wood burns? For example, how do you think density would be related to burning rate? Why? Measure the density and… Read more

Which Metal Is the Most Resistant to Corrosion?

Science Fair Project Idea

Scientific Method

Here's a practical engineering challenge: you need to build an enclosure for your dogs, using material that they can't chew through. It's going to be a lot of work to build, so you want to do it right. What material should you choose for the fencing? This project uses the scientific method to evaluate materials. Read more
