Which Acne Medication Can Really Zap That Zit?

Science Fair Project Idea

Scientific Method

Have you ever wondered where acne comes from and how you can treat it? One major cause of acne is the colonization and infection of clogged pores with bacteria. In this science project, you'll test different acne medications and treatments to determine their effectiveness at killing bacteria. Read more

Which Team Batting Statistic Predicts Run Production Best?

Science Fair Project Idea

Scientific Method

Here's a sports science project that shows you how to use correlation analysis to choose the best batting statistic for predicting run-scoring ability. You'll learn how to use a spreadsheet to measure correlations between two variables. Read more

Which Wing Design Creates the Greatest Lift?

Science Fair Project Idea

Scientific Method

Have you ever flown in an airplane, or looked up at one flying in the sky, and wondered how such a massive machine can stay in the air? Airplanes can stay in the air because their wings, also referred to as airfoils, generate lift. Engineers use devices called wind tunnels to experiment and test different wing shapes when they design new airplanes. Wind tunnels let engineers make careful measurements of the air flow around the wing, and measure the amount of lift it generates. If you can get… Read more

Why Are Teens Stressed?

Science Fair Project Idea

Scientific Method

What causes the most stress for teenagers? Is it school? family relationships? peer pressure? worries about the future? Design a survey to find out what contributes to teens' stress levels. Possible variations include: How do teenagers deal with stress? Are today's teens more or less stressed than their parents were as teenagers? Were the sources of stress the same for your parent's generation or different? (Idea from De Biasi, 2003) Read more

Why Do Birds Fly in a V-formation?

Science Fair Project Idea

Scientific Method

Have you ever wondered why geese fly in a V-formation? In this science fair project, you will build a wind tunnel to test how the formation of birds in flight actually affects their flight efficiency. Read more

Why Do Flying Rings Go So Much Further Than Frisbees?

Science Fair Project Idea

Scientific Method

If you've played catch with both Aerobie flying rings and Frisbees, you know that the rings fly much further than the Frisbees with the same throwing effort. Why is that? Investigate the aerodynamics of flying rings and flying disks and find out! Read more

Wily Waves: Build an Oscillating Water Column to Extract Energy from Ocean Waves

Science Fair Project Idea

Scientific Method

The ocean is a wondrous force of nature. It affects the weather, and provides us with food and renewable energy to power our lives. How can the ocean provide us with renewable energy? One way is to extract the energy that is in the waves. There are many kinds of power systems that can be installed to extract energy from the waves, depending on the location. In this energy and power science project, you will build and test a simple model of an oscillating water column device to create power. How… Read more

Students will explore the elements by designing a wind maze, a device that can direct the wind along a specific path. Learning Objectives Students will: Design and test a wind maze. Consider how to direct the wind down an intended path by creating bends in the maze. Use observations from their tests to compare solutions and iterate on their designs. NGSS Alignment This lesson helps students prepare for these Next Generation Science Standards Performance Expectations: … Read more

Wind Turbine Efficiency

Science Fair Project Idea

Scientific Method

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

Wood vs. Alternative and Recycled Materials

Science Fair Project Idea

Scientific Method

Our forests are a very important natural resource that need to be managed wisely. We use wood products for many different purposes: building materials, paper, cardboard, furniture, fuel, etc. How can we use wood products in a sustainable manner? You can do experiments that examine the growth time of different tree species to see which are good candidates for tree farming. Which types of lumber are most sustainable? You can also compare the effects of clear cutting vs. thinning a forested… Read more
