Science Fair Project Idea

Scientific Method

You'll need: a puck, a hockey stick, a tape measure, at least one helper with a stopwatch and an empty rink. Have your friend start the watch just as you make contact with the puck, and stop it when the puck hits the boards. Measure the distance and divide by the time to get the speed of the puck. With two helpers and two stop watches, you can time the puck at center ice and at the far end. Are the speeds the same? How about if you don't follow through, but stop your stick as soon as it… Read more

How Fatigue Changes Balance

Science Fair Project Idea

Scientific Method

Balance is one of the most important parts of how our bodies work. Even standing still requires the brain, muscles, eyes, and inner ears to coordinate perfectly. But what happens when you get tired—even just a little bit—from something like dancing, running, jumping in place, or doing step-ups for a short period of time? Many scientific studies show that fatigue—both mental and physical—can make balance worse. For example, after short bursts of physical activity, people… Read more

How Many Letters?

Science Fair Project Idea

Scientific Method

Can you remember all of your ABC's? Computers need to "remember" letters too. Every time we use a computer to write a story, the computer needs to "remember" the letters in the story by saving them to the computer's memory as a file. In this experiment find out how much memory it takes for the computer to "remember" a series of letters. Read more

How Much Worm Is a Worm?

Science Fair Project Idea

Scientific Method

Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more

How Rain Gardens Fight Pollution and Flooding

Lesson Plan Grade: 3rd

Students might think rain gardens are only there to make an urban area look nice. In this lesson, students will make mini rain gardens and discover how these can filter out pollution and soak up excess rainwater. Will they find how rain gardens help prevent natural disasters? Try out this fun lesson and see! Read more

NGSS Performance Expectations:

3-ESS3-1. Make a claim about the merit of a design solution that reduces the impacts of a weather-related hazard.

How Shoe Tread Affects Traction

Science Fair Project Idea

Scientific Method

Have you ever noticed that some shoes grip the ground better than others? The pattern and design of a shoe’s tread can affect how slippery it is on different surfaces. You can test shoes with different tread patterns—like flat, ridged, or patterned—to see which design provides the best grip. By dragging a shoe along a surface with a spring scale at a constant velocity, you can measure how much force is needed for each shoe to slide on various surfaces. With this knowledge, you… Read more

How Things Break

Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more

Image Compression

Science Fair Project Idea

Scientific Method

Compare the strengths and weaknesses of different digital image formats. How does the amount of compression affect a JPEG image? What happens when you save a JPEG image multiple times? Read more

Image Compression vs. Image Quality: Finding the Best Tradeoff

Science Fair Project Idea

Scientific Method

In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality. Read more
