Rock On! Recording Digital Data with Magnets

Science Fair Project Idea

Scientific Method

This is a straightforward project that shows you how data can be digitized and stored on magnetic recording media. You'll learn how alpha-numeric characters are digitized, and you'll use bar magnets to represent the individual data "bits." You'll also learn about how much information can be stored in a small space (recording density), and how magnetic data can be erased. Read more

How Many Seeds Do Different Types of Fruit Produce?

Science Fair Project Idea

Scientific Method

Do you like your strawberry jelly with or without the seeds? Are you glad to have a seed-free watermelon, or do you enjoy spitting the seeds into the garden? You might not like to find seeds in your fruit, but fruit is the plant's way of dispersing seeds to make new plants. How many seeds can be dispersed for each type of fruit? As they say, in one end and out the other! Read more

Use the Sun's Energy to Heat Your Own Water

Science Fair Project Idea

Scientific Method

Isn't it nice to take a nice, hot shower or bath after a long day of playing outside? But have you really thought about how the hot water in your shower or bath gets hot? Sure, the water heater in your house gets it hot, but what makes the water heater work? Water heaters are powered by natural gas or electricity. But are there any other ways to heat water? What about using the Sun? In this science fair project, you'll give it a try by capturing energy from the Sun to heat water. Read more

Do the Eyes Have It?

Science Fair Project Idea

Scientific Method

Some people have a photographic memory and can memorize anything they see almost instantly! Wouldn't that make homework easy? Other people can remember almost anything they hear. Try this experiment to see which type of memory you have. Read more

Air Pollution

Science Fair Project Idea

Scientific Method

Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. … Read more

Experiment with Making Gels

Science Fair Project Idea

Scientific Method

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more

The Taylor Swift Challenge

Science Fair Project Idea

Scientific Method

Taylor Swift famously got in shape for her three-hour-long Eras Tour concerts by singing all 40+ songs...while running on a treadmill! Have you ever tried running while singing at the top of your lungs? How hard do you think it is? In this science project you will measure the impact talking and singing have on a group of volunteer runners. Is anyone in better shape than Taylor Swift? Read more

Are Enzymes in Laundry Detergents Effective Stain Removers?

Science Fair Project Idea

Scientific Method

Some laundry detergents have added enzymes that break down proteins, helping to remove them from the cloth fibers, and thus remove stains. You can perform a scientific test of these enzymes' stain-fighting ability. Do background research on the enzyme(s) in the detergent, and on the substances you choose for making the stains. Try to predict for which substances the enzymes will be effective. Cut a piece of light-colored cotton cloth into identical 10 cm squares. Choose different… Read more

The Touch Response

Science Fair Project Idea

Scientific Method

All animals need to respond to changes in their immediate environment. The sensory structures of animals are each made to respond to distinct types of sensory stimuli: touch, taste, sound, light and smell. How are these stimuli received? Different animals have different strategies for receiving stimuli and develop specialized structures for doing so. Antennae, ears, noses, tongues, eyes, eye spots, hairs and bristles are all examples of sensory structures used by different animals to sense… Read more

Build & Test a Search-and-Rescue Robot

Science Fair Project Idea

Scientific Method

Have you ever heard of the NASA Mars rovers Spirit, Opportunity, Curiosity, and Perseverance? How about the "bomb squad" robots that police and the military use? These are places that are hard for us to reach (Mars), or dangerous for us to be near (explosives). Because the human operators are usually far away from the robot, driving one is different from driving a car. Operators rely on information sent back from the robot, including pictures and video. In this project, you will build your… Read more
