Which Is the Better Insulation Material?

Science Fair Project Idea

Scientific Method

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? 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 Liquid Works Best for Evaporative Cooling?

Science Fair Project Idea

Scientific Method

When we get hot, we sweat. Sweating helps cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes using what are referred to as swamp coolers. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

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

Which Orange Juice Has the Most Vitamin C?

Science Fair Project Idea

Scientific Method

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Which Wheat Flour Has the Most Gluten?

Science Fair Project Idea

Scientific Method

Close your eyes for a moment and think about your favorite cake, pasta, and crusty bread. OK, you can open your eyes now, and please do not drool on your computer! What was the cake you pictured like? Was it light and fluffy? Did you imagine pasta with a silky, smooth texture? Was the bread you pictured wonderfully chewy? Did it give your jaws a workout? In this science fair project, you will explore an amazing substance in these foods, called gluten, and discover why these foods, all made from… 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 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

Why Does the Moon Appear Larger at Some Times?

Science Fair Project Idea

Scientific Method

Some claim the Moon appears larger when near the horizon. Make a series of observations of the Moon, measuring the Moon's angular diameter each time. You should also note the Moon's altitude above the horizon, and the Moon's phase. You should do background research on the lunar orbit to determine the necessary time period. Do you find predictable variations in the Moon's diameter? Can you relate this to the Moon's changing distance from Earth? From your data, try to determine when apogee and… Read more
