Breath of Life: Does Exercise Increase Vital Capacity?

Science Fair Project Idea

Scientific Method

How much air do you think you breathe in when you take a deep breath? Can you increase your lung capacity by exercising regularly? Do athletes have greater lung capacity than non-athletes? This project shows you how you can find out. Read more

Bridge Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: an civil engineering project that lets students and families experiment with bridge design. You may be familiar with famous suspension bridges like the Golden Gate Bridge in San Francisco, but how does a suspension bridge really work? How do the cables work to support the weight on the bridge? Can a suspension bridge carry a greater load than a beam bridge? With common household materials, you can put your own straw-based bridges to the test. How many pennies can… Read more

Bringing Science Magic to the Classroom

Blog Post

A magic milk rainbow may be all about what's happening at the surface level between milk and soap, but when kids create the magic, the learning excitement is palpable. For Lily Arendt, hands-on science activities are a great way to help kids uncover the magic of science. We couldn't agree more! Above: Lily Arendt and a class of students explore surface tension with the Make a Milk Rainbow science activity. For Lily Arendt, a biology student at DePaul University in Chicago and a… Read more

Bubbly Soda Science: Weekly Science Activity

Blog Post

Making your own carbonated beverage can be a lot of fun. How much fizz do you like? What flavor? How sweet? The process of carbonating water and serving up a custom beverage is easier than ever before thanks to commonly available household devices like Sodastream®. But a pressurized approach to creating a carbonated beverage is not the only way to prepare a refreshing soda-style drink. With a few simple ingredients, students can experiment with mixing up their own… Read more

Bug Vacuums: Sucking up Biodiversity

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

What in the world is a differential and what does it do? A differential is a mechanism that helps cars go around turns without the wheels slipping. In this activity you will build your own working model differential from a building toy like K'Nex®! 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 Radio-Controlled (RC) Robot

Science Fair Project Idea

Engineering Design Process

Radio-controlled (RC) robots can explore places that are difficult or dangerous for humans to get to, like collapsed buildings after a natural disaster. They can use cameras and a variety of other sensors to gather information about their environment, like the presence of toxic gases or other hazardous materials. The robots can even use grippers and robotic arms to collect and safely dispose of some materials. You can build your own RC robot using the Science Buddies Bluebot kit, Electronics… 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
