Turn Plants into Biofuel with the Power of Enzymes

Science Fair Project Idea

Scientific Method

Are biofuels the wave of the future? People often talk about these plant-derived fuels as a way to someday cut down on our dependency on non-renewable carbon-based fuels, like gasoline. Ethanol (a type of alcohol) is a common biofuel used today. In the United States, ethanol is a common biofuel additive to normal gasoline. In fact, some states mandate that when you fill up your gas tank, 10 percent of the total fuel volume be made of ethanol. Brazil, the world's second largest user of… Read more

Understanding Lactose Intolerance

Science Fair Project Idea

Scientific Method

What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

Understanding Wolf Behavior from GPS Tracking Data

Science Fair Project Idea

Scientific Method

If you were leaving home for a long walk, how far would you go? One mile, 5 miles, 10 miles? How about 550 miles?! That's a long way, but some wolves have been known to travel that far when they are leaving their packs in search of a mate so they can form their own pack. But is that how far wolves normally travel? Try this wild wolf tracking science fair project to find out! Read more

Are you ready to bend light, magnify letters, and have fun with drops of water—all while getting a glimpse into how lenses work? Lenses are the key components in eyeglasses, contact lenses, binoculars, telescopes, and magnifying glasses, just to name a few devices. With this activity, a homemade magnifying glass is only a drop away! Read more

Use Super-strong Magnets to Make a Simple Motor

Science Fair Project Idea

Scientific Method

In this science project, you will build what might be the world's simplest motor. It has just four basic parts: magnets, a battery, a screwdriver, and a short piece of wire. It takes only minutes to assemble, but it provides a wonderful device to explore how electricity and magnetism combine to produce a fast-spinning motor. Read more

Using AI to Detect Proper Exercise Form

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how Artificial Intelligence (AI) can be used to improve human health and medicine? Computers can now identify human joints as key points to track our body movements. They can then use this information along with training data sets to show us if we perform exercises safely, to prevent us from getting injured. Create your own data set and test out if your algorithm can reliably detect good and bad exercise form. Read more

Volcanoes

Science Fair Project Idea

Scientific Method

The papier-mâché volcano is a real classic, but there are many other ways to make an even more exciting and interesting science project focused on volcanoes! To get started on your own volcano-based science project, you will want to first have an understanding of how volcanoes form. This is related to tectonic plates. The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large tectonic… Read more

Water to Fuel to Water: The Fuel Cycle of the Future

Science Fair Project Idea

Scientific Method

Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In this… Read more

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more

Which Stars Can You Use for Navigation in Different Parts of the World?

Science Fair Project Idea

Scientific Method

Do you ever wonder how pirates sailed the seven seas? The two most important things a pirate could have (besides a parrot and big hat) were a compass and an accurate watch. Ancient navigators didn't know about compasses, so how did they know where they were going? Could they have used the stars to know which way to go? Read more
