How Can Tofu Pack Such a Flavorful Punch?

Science Fair Project Idea

Scientific Method

Spicy fried tofu. It's a delicious and savory main dish at many Asian restaurants. Stab a golden-brown piece, bite into it, and the juice inside rushes out, filling your mouth with rich flavors. Continue eating and you find the texture is very chewy and meat-like. Did you ever wonder how those white blocks of tofu you see in grocery stores are transformed into the chewy little sponges packed with flavorful juices you see in Asian restaurants? Try this cooking and food science fair project to… Read more

Learning Your A, G, C's (and T, too)

Science Fair Project Idea

Scientific Method

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this new alphabet. Read more

When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

Squirrel Obstacle Course: How Far Can Squirrels Jump?

Science Fair Project Idea

Scientific Method

This project idea is inspired by former NASA engineer Mark Rober's "Squirrel Ninja Obstacle Course". You do not need to build a full obstacle course as intricate as Mark's (although you certainly can if you want to!) to make this into a fun science project. For example, how far can squirrels jump? You could test this question by building a mobile post and placing it next to a bird feeder. The bird feeder in Figure 1 is mounted on a metal pole. The pole is protected by a squirrel baffle, a… Read more

Foggy Forecasting: What Weather Factors Create Radiation Fog?

Science Fair Project Idea

Scientific Method

The poet Carl Sandburg wrote, "The fog comes on little cat feet..." In this weather science fair project, you'll discover why this beautiful, quiet creeper appears on some days, and not on others. If you are fascinated by fog and weather conditions, this science fair project is for you! Read more

How Food Supplements Affect Weight Gain of Juvenile Mice

Science Fair Project Idea

Scientific Method

As your mom and dad always tell you, a healthy diet is important to good health. This project is designed to see what happens to mice when they are allowed to load up on sugary snacks. Do you think that they will gain excess weight? Do you think that the mice will regulate their own intake and maintain a 'healthy' diet? You can try this project and find out for yourself. Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more

She Shoots, She Scores! How Does Hockey Stick Flex Affect Accuracy and Speed?

Science Fair Project Idea

Scientific Method

While watching an ice hockey game, have you ever wondered what differentiates a good player from a great player? For sure, the great player is athletically superior to the good player. But maybe it is a combination of athleticism and equipment. Maybe a great player knows which hockey stick is best for him or her. Hockey players can choose to play with hockey sticks with different flexibilities or "flex." In this science fair project, investigate how stick flex affects shot accuracy and speed.… Read more

Astronaut Stress Management Training for Space Flight

Science Fair Project Idea

Scientific Method

Training for space flight isn't just a physically demanding job. You need to be prepared mentally and emotionally, too! In this science project, you will test how a breathing technique can improve your fight-or-flight response induced by the stressors of space flight. Read more
