Which Bait Works Best for a Homemade Fly Trap?
Science Fair Project Idea
Scientific Method
Do you really catch more flies with honey than with vinegar? Do an experiment to find out! Watch the video above to learn how to make a simple homemade fly trap using a plastic bottle. Then, experiment to discover which bait attracts the most flies. You can try a variety of liquids, and you can also use solid bait like rotting food or meat, but you will need to add some water so the flies drown. A drop of soap can help break the surface tension of the water, making it easier for the flies to… Read more
Lift a Load Using Hydraulics
Science Fair Project Idea
Scientific Method
Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more
The Height Limits and Linearity of Bouncy Balls
Science Fair Project Idea
Scientific Method
You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. Read more
The Dynamics of a Bouncing Ball
Science Fair Project Idea
Scientific Method
Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more
Make the Fastest Rubber Band Paddle Boat
Science Fair Project Idea
Engineering Design Process
Rubber band paddle boats are a fun bathtub or pool toy that you can build yourself. How do you make a boat that goes the fastest? Find out in this project as you build and test your own boat. Read more
Make Yogurt Spheres Using Molecular Gastronomy
Science Fair Project Idea
Scientific Method
Imagine if instead of spooning up a bowl of soup, a container of yogurt, or a cup of pudding you could just pick up and pop in your mouth a round, mess-free, ball-like blob of one of those. It might feel like snacking rather than eating a meal! In this food science project you can try exactly that. The simple step-by-step directions will lead you through trying a fun cooking technique called reverse spherification to turn yogurt into semi-solid balls, which are called "raviolis." How do you… Read more
Make Sustainable Fabrics from Seaweed
Science Fair Project Idea
Scientific Method
Can you imagine clothing, handbags, or shoes made from seaweed or spider silk? To become more sustainable, the textile industry is looking for ways to develop more eco-friendly fabrics. Biofabrics derived from living organisms such as seaweed or bacteria have been proposed as a potential alternative to conventional fibers. In this science project, you will make several biofabrics from alginate (seaweed) and conduct tests to find out which one is most suitable as a textile replacement. Read more
Create and Test Your Own Hydrogel Face Mask Recipe!
Science Fair Project Idea
Engineering Design Process
Have you ever tried a beauty face mask? Cosmetic face masks are skin care products that promise rapid hydration of your skin to make it look younger and more radiant. Hydrogel face masks are made of jelly-like materials that are infused with special ingredients to nurture your skin. The ingredients for cosmetic products like face masks are carefully selected by cosmetics chemists. Each product is designed to have the properties that are necessary for its intended purpose. In this science… Read more
Take a Candle Carousel for a Spin
Science Fair Project Idea
Scientific Method
Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more
Design Your Own Slime
Science Fair Project Idea
Engineering Design Process
There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more
