Build and Test a Sun-Tracking Solar Panel

Science Fair Project Idea

Scientific Method

How can you get as much power as possible out of a solar panel, even in the morning or evening when the sun is low in the sky? With a solar tracker system! While many solar panels are fixed in place on rooftops or large ground-mounted poles, a solar tracker system is motorized and lets the solar panels track the sun through the sky during the day. Are these systems worth the added complexity? How much more power do they produce? Try this project and find out! Read more

Do you like arts and crafts projects like drawing, painting, cutting shapes out of construction paper, or origami? Instead of drawing that bright sun or lights in a house, imagine adding real lights to your artwork! This project will show you how, by introducing you to the world of electronics with "paper circuits." Paper circuits are made with just a few simple items; you can use a battery and some copper tape to add tiny lights to your project. The best part is that it is easy to do, and you… Read more

Remove Microplastics from Water with Bioremediation

Science Fair Project Idea

Scientific Method

Have you ever walked by an ocean, lake, or river and seen plastic trash? Have you ever wondered how microplastics might be impacting the creatures living in these places? In this science project, you will investigate how yeast can be used in bioremediation to remove microplastics from contaminated water. Read more

How to Make a Battery with Metal, Air, and Saltwater

Science Fair Project Idea

Scientific Method

Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more

Make a Robot Hand Using Drinking Straws

Science Fair Project Idea

Scientific Method

Imagine how cool it would be to build a robot hand that could grasp a ball or pick up a toy. In this robotics engineering project, you will learn how to use drinking straws, sewing thread, and a little glue to make a remarkably lifelike and useful robot hand. What will you design your robot hand to do? Pick up a can? Move around a ping pong ball? It is up to you! With these starting instructions, you can design any type of hand. You will simulate human finger anatomy as the basis for a… Read more

Rocking the Boat

Science Fair Project Idea

Scientific Method

When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! Read more

Ocean Bioluminescence: Investigate When and How Dinoflagellates Glow

Science Fair Project Idea

Scientific Method

Imagine the ocean water turning bright red or seeing ocean waves glowing a beautiful blue color. Sounds impossible—but it is not! Red tides and glowing waves are caused by microscopic organisms living in the ocean called dinoflagellates. Some dinoflagellates have the ability to produce light through a process called bioluminescence. When and how do these organisms glow? In this science project, you will investigate how changing the dinoflagellate's exposure to light and dark affects its… Read more

What Materials Can Block a Wi-Fi Signal?

Science Fair Project Idea

Scientific Method

Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router. Read more

How the Strength of a Magnet Varies with Temperature

Science Fair Project Idea

Scientific Method

Physicists sometimes study matter under extreme conditions. For example, think of the emptiness of interstellar space vs. the unimaginable crush of pressure at the center of a neutron star, or an object dipped in liquid nitrogen vs. the tiles on the space shuttle during re-entry. Here's an experiment on permanent magnets in "extreme kitchen" conditions that you can try at home. Read more
