Printing Power! Save the Environment, One Printer Page at a Time

Science Fair Project Idea

Scientific Method

Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to… Read more

You've Got Permission to Be a Backseat Driver!

Science Fair Project Idea

Scientific Method

Do you like to tell adults where to go and how to get there? Well, here's your chance to do it in the name of science! In this science fair project, you will see what happens to your car's fuel efficiency when it takes you downtown to see a movie, up a hill for a great view, or out for a cruise on a flat country road.

Do People Prefer Virtual Reality Headsets over 2D Pictures?

Science Fair Project Idea

Scientific Method

Are you convinced that virtual reality (VR) will soon become mainstream and improve our lives in unpredicted ways? Or maybe you believe it is a big hype doomed to fade and disappear. In this science project, you will use one aspect of VR—the headset—and investigate if it could convey reality better than traditional pictures or 360° images. You will go out and measure how people perceive pictures and images you took. Will people embrace the VR headset and what it can do or… Read more

Toxic Trees: Just How Toxic is That Black Walnut Tree?

Science Fair Project Idea

Scientific Method

Every spring, gardeners around the world get ready to plant their summer gardens. They turn the soil over in their garden plots and add nutrients to the soil. Then they plant their seedlings and wait for nature to provide a bounty of fruits, vegetables, and flowers. But nurturing the garden doesn't stop there. In order to get lots of fruits and vegetables, the gardener must eliminate factors that can hurt the plants. Sometimes, chemicals in the soil from other plants and trees can hurt a… Read more

Tee Time: How Fast is Your Golf Swing?

Science Fair Project Idea

Scientific Method

The goal of every golfer is to hit the golf ball as far as possible down the fairway. A key factor in determining the distance that the ball will travel is the velocity of the club when it strikes the ball. In this sports science fair project, you will determine exactly how distance is related to club velocity. Time to tee off! Read more

Flight Simulators: From Flaps to Flying

Science Fair Project Idea

Scientific Method

Did you know that commercial airline pilots use high-tech flight simulators to learn how to fly big jumbo jets? Before they ever step behind the controls of a real jet they've already logged thousands of virtual air miles. It might not qualify you to fly a real jumbo jet, but you, too, can learn the logistics of aviation by experimenting with the types of flight simulators sold at computer game retailers. Use a flight simulator to investigate the relationship between flap settings and the stall… Read more

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Do Heavy Loads Shorten Your Steps?

Science Fair Project Idea

Scientific Method

You probably notice that when you carry something heavy—whether it’s a backpack filled with books, grocery bags, or a weighted vest—the way you walk changes. Your body adjusts in many ways to maintain balance, avoid fatigue, and reduce injury risk. One of these adjustments happens in your step length—that is, how far you move forward with each step. Biomechanical studies show that adding extra load (weight) often causes people to take shorter, more cautious steps. This… Read more

Which Animals Have Genome Projects?

Science Fair Project Idea

Scientific Method

All animals have a genome, but do they all have genome projects? Find out which animals are currently having their genomes sequenced and how much we know already. Whose genomes are already finished? Whose genomes are just getting started? Find out by doing some simple bioinformatics data digging! Read more

Skiing and Friction: How Does Ski Wax Affect the Sliding Friction of Skis?

Science Fair Project Idea

Scientific Method

You can model this with an ice cube sliding down a plank: how high do you need to lift the end of the plank before the ice cube starts to slide? Try this with one side plain wood and the flip side waxed wood (use paraffin wax, candle wax or ski wax). Make sure both sides are equally smooth to start with. Do at least three trials. More advanced: using what you know about the forces acting on the ice cube, derive equations to calculate the coefficient of friction for each case. Variation: chill… Read more
