Science Fair Project Idea

Scientific Method

Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Build a Color-Detecting Rover

Science Fair Project Idea

Engineering Design Process

The Mars Curiosity and Perseverance rovers use scientific instruments, nicknamed ChemCam (Figure 1) and SuperCam respectively, to help them analyze the composition of rocks and soil on Mars. You can learn more about these cameras from the resources in the Bibliography, and more about why scientists want to analyze rocks on Mars from the video on this page. Figure 1. The two main parts of the ChemCam instrument on the Mars Curiosity rover. For a science… Read more

Build a Light-Up Activity Timer

Science Fair Project Idea

Engineering Design Process

Do you have trouble remembering when to stop playing and clean up? Have you ever had little kids throw a tantrum about cleaning up while you were babysitting? If so, this project is for you! You will convert a stuffed animal into a light-up activity timer. You can use the timer for different activities like play, exercise, or doing homework. What you use it for is up to you! Read more

Build a Wearable Device Using an Arduino to Keep Astronauts Safe on Mars

Science Fair Project Idea

Engineering Design Process

Astronauts on Mars missions must be protected from hazardous environments, like steep cliffs, rocky terrain, and extreme temperature variations. How can geofencing help? In this project, you will design a system that uses geofencing technology coupled with biosensors to ensure astronaut safety. The system will create a virtual boundary around astronauts, providing alerts if they approach dangerous areas or leave designated safe zones, or if their vital signs fall below a certain threshold. Can… Read more

Build an Adaptive Game Controller for a Raspberry Pi

Science Fair Project Idea

Engineering Design Process

People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more

Build Personal Playlists with Machine Learning

Science Fair Project Idea

Scientific Method

AI has the power to organize data into categories—even when it is not given clear instructions. In this project, we will create an unsupervised K-Means learning model that organizes songs into distinct groups based on their similarities. The best part? You don't need advanced coding skills; just bring an open mind and a desire to explore the fascinating intersection of music and technology. Are you ready to embark on this exciting journey?

Build Your Own Xylophone Out of Copper Pipe

Science Fair Project Idea

Scientific Method

Did you know that making a musical instrument is not just an art, but a science, too? You can discover just how scientific by building your own xylophone (or a set of chimes) from copper pipe. First you'll need to do some research about the math and physics involved in the sounds of a xylophone. For example, there are equations that describe the transverse (side-to-side) vibrations of a pipe. These vibrations create the sounds you hear. So, to get specific sounds, xylophone makers must apply… Read more

Building Paper Bridges: Family Science Spotlight

Blog Post

Build bridges from paper to explore civil engineering in this family STEM activity. Does the shape of the materials make a difference? What helps make a bridge strong? In this family science activity, explore bridge engineering with kids by making paper bridges that stretch between stacks of books. How does changing the shape of the materials (the paper) change the strength of the bridge? This is a fun and creative science activity you can do with… 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
