Spinning Your Wheels: Pinwheel Sensitivity

Science Fair Project Idea

Scientific Method

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more

Spinning Colors: How Do Primary Colors Combine to Make New Colors?

Science Fair Project Idea

Scientific Method

Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Sound Bites: Tasting the Texture of Classical Music

Science Fair Project Idea

Scientific Method

Have you ever bitten into a thick, fragrant casserole and tasted the layers of flavor? Or maybe you've licked of a vanilla ice cream cone and thought, "This is so pure, simple, and refreshing!" These observations about the taste of the food are also comments on its texture—the casserole is complex and thick, and the vanilla ice cream cone is simple and thin. You might not realize it, but sound can also have texture. In this music science fair project, you'll learn how to "taste" the… Read more

Veggie Snap! Modifying Bending Stresses in a Flexible Rod

Science Fair Project Idea

Scientific Method

Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more

Dye Eggs Using Silk Ties for Egg-cellent Colors

Science Fair Project Idea

Scientific Method

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! To do this, most people buy dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. You can dye eggs in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this science project, you will dye eggs with old or used… Read more

Which Simple Machines Do I Use the Most?

Science Fair Project Idea

Scientific Method

When you think of a machine, you probably think of computers or robots. But what if I told you that machines have been around for centuries? Would you believe me? Try this experiment to see which of these simple machines you use around your house. You might even use some of them everyday! Read more

With a Little Bread as Bait, Can You Make a Bird Migrate?

Science Fair Project Idea

Scientific Method

You might like to play in the autumn leaves and winter snow, but have you noticed that many birds don't like to stick around for the cold weather? And instead of the birds you're used to seeing in the warm months, your new feathered friends might be Canada geese. Why is that? Various types of birds and other animals travel from one place to another either in search of food, warmer temperatures, or other things they need to survive. This type of traveling is called migration. Try starting your… Read more

Who Has the Biggest Genome?

Science Fair Project Idea

Scientific Method

Humans are complex creatures, but do we have the biggest genome? All living things, from humans to worms to bacteria have genomes. In this experiment you will compare the genome sizes of different organisms to find out who has the smallest and the largest genomes. Where will we fit in? Read more

Changing Constellations

Science Fair Project Idea

Scientific Method

Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more

Primary Productivity and Plankton

Science Fair Project Idea

Scientific Method

Have you seen plankton? I am not talking about the evil villain trying to steal the Krabby Patty recipe from Mr. Krab. I am talking about plankton that live in the ocean. In this experiment you can learn how to collect your own plankton samples and see the wonderful diversity in shape and form of planktonic organisms. Read more
