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

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

If you pour water into a clear glass, what color is it? It’s clear, right? But what happens if you try to look through it to see the world on the other side of the glass? It looks a little distorted, maybe a little fuzzier and uneven. If water is clear, why can’t we see through it clearly? The answer has to do with how light moves through water, glass, and other transparent materials. Just like when you try to run in a swimming pool, when light tries to move through water or glass,… 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

Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (like in a lamp with a single light bulb) to very complex (like in a computer). Try this project to build your own simple circuit and use it to test which common household materials conduct electricity. Read more

Yeast Reproduction in Sugar Substitutes

Science Fair Project Idea

Scientific Method

There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more
