Water-Wise: Building a Rainwater Collection System
Science Fair Project Idea
Scientific Method
We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more
Fresh Whipped Cream That Lasts
Science Fair Project Idea
Scientific Method
Fresh whipped cream is the final touch for many delectable desserts. One issue with fresh whipped cream is that it has to be used soon after it is made, especially if it is at room temperature, or it starts to collapse into goo. This is a problem for its use in frostings or inside pastries as filler. Whipped cream can be stabilized by adding unflavored gelatin. Stabilized whipped cream can be used at room temperature and it has a much longer life. But how much gelatin is just right? Try… 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
Worm Hunt: Isolating Soil Nematodes from Your Backyard
Science Fair Project Idea
Scientific Method
Do you know what is living in your backyard? How about at the playground, or in your compost pile? Nematodes, also called roundworms, are the most abundant animal on Earth and they might be living in any of these places. In this science project you'll isolate nematodes from several soil samples to discover the best nematode habitats. Read more
Top Crops: Finding Hidden Grasses and Beans in Processed Foods
Science Fair Project Idea
Scientific Method
It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more
Energy Is Blowing in the Wind
Science Fair Project Idea
Scientific Method
Have you ever watched how trees sway and bend in a strong wind? Have you ever thought about all the homes that could be powered with forces from the wind? In this project you'll discover, through trees, good places in your community for generating wind power. Read more
That's a Pretty Tough Baby! A Study of Gender Stereotypes in Children
Science Fair Project Idea
Scientific Method
Have you ever seen a baby in the park and wondered if it was a boy or a girl? Maybe once you found out the gender, you thought how sweet, mischievous, or cute the baby was. But wait…do you think that the words you used to describe the baby might be based on your own gender stereotypes? A gender stereotype is when you expect someone to act a certain way simply because he or she is a boy or a girl. In this human behavior science project, you will investigate whether young children use gender… Read more
Color Profiles
Science Fair Project Idea
Scientific Method
Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job? Read more
How Can Your Faucet Save Water?
Science Fair Project Idea
Scientific Method
One way to save water is to turn the faucet off while you brush your teeth. But did you know that there are products that can help save water even while the water is on? In this experiment find out how low-flow faucets and aerators work to reduce the flow of water. How much water can you save? Read more
Pinholes, Light and Aperture Size
Science Fair Project Idea
Scientific Method
Pinhole cameras are not just for grannies! Even compared to all of the latest technology, a pinhole camera still gets beautiful results. Find out how this very simple aperture design works to control the way light enters the lens of your camera. Read more
