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

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more

A Cool Way to Make Electricity: Solar Cell Power Output vs. Temperature

Science Fair Project Idea

Scientific Method

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature. Read more

Are More Expensive Golf Balls Worth It?

Science Fair Project Idea

Scientific Method

There is a bewildering selection of different golf balls to choose from for playing the game. Some less expensive, some more expensive, all with different claims for the advantages they will bring to your game. This project can help you determine which type of golf ball is right for you. Read more

73 reviews

Different types of birds lay their eggs in different places. Some build tiny nests in bushes, some build enormous nests in tall trees. Some lay their eggs directly on the ground or on rocky ledges. Those that build nests use many different types of materials. In this project you will try to build your own bird nest using only natural materials that you can find outside. Can you do better than a bird? Read more

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Build an Obstacle-Avoiding Robot (BlueBot Project #4)

Science Fair Project Idea

Scientific Method

In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

Build Your Own Microfluidic Device

Science Fair Project Idea

Engineering Design Process

Microfluidic devices are small tools used in different fields like engineering and biomedicine. Scientists and engineers use these devices to work with very tiny amounts of fluids for various experiments. These experiments can include things like biomedical research, creating new medicines, and even applications in the car industry. In this project, you will create and test your own microfluidic device design and compare it to other designs. Read more

Building Structures: It's a Slippery Slope

Science Fair Project Idea

Scientific Method

Have you ever looked up at a skyscraper and thought "That is so cool!"? Building a skyscraper, or any structure, is more than just building the walls, windows, and floors. All structures require a foundation to keep them from falling down. This is especially important when a structure is built on a hill or on a slope. In this science project, you will build a tower of Lego® Duplos® on slopes with different angles. You will investigate how deep you have to dig the foundation for each… Read more

Can Gaming Help You Score Better in School?

Science Fair Project Idea

Scientific Method

Can computer games be used to educate? Pick a game that incorporates educational material. There are a variety of educational computer games on the market in the areas of math, history, science, and language, as well as many simpler versions free on the Internet. Make up a test based on the subject area covered by the computer game. Have your volunteers take the test before and after playing the game. Does playing the computer game improve people's score on the test? Read more
