Pizza Box Solar Oven: Weekly Science Activity

Blog Post

In this week's spotlight: an energy-focused family science activity that doubles as an alternative energy experiment and a recycling project. Using a pizza box (or other shipping box), foil, a few other readily available materials, and the power of the sun, you can make a functional solar-powered oven. Cooking will take longer than in a kitchen appliance, but with some planning, you can cook a meal or prepare a campsite batch of s'mores with your own homemade solar oven! How does a solar… Read more

Play an Electronic Drumset with a Raspberry Pi

Science Fair Project Idea

Scientific Method

When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a… Read more

Play-Doh Math

Science Fair Project Idea

Scientific Method

Have you ever had fun making different figures or colorful creations using some Play-Doh? You can squish and stretch a single piece of Play-Doh® to make all sorts of shapes. How does changing the shape of a piece of Play-Doh affect its volume? In this science project, you will find out by testing how changing a piece of dough's shape affects its dimensions (length, width, and height), and how these changes are related to the dough's volume.

Playing the Angles: The Physics of Balls Bouncing Off of Surfaces

Science Fair Project Idea

Scientific Method

Think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll the marble at… Read more

Pop Goes the Geyser!

Science Fair Project Idea

Scientific Method

Our home, Earth, is a living planet. Earthquakes and volcanic eruptions are proof that the geological forces that shaped our planet and created the land masses are ongoing. An amazing example of geologic activity that is less damaging is a geyser. In this geology science fair project, you will build a model geyser and determine how depth of the source affects how the water is ejected. By the end of this project, you will know a lot more about geysers and understand that a geyser is much more… Read more

Powering a Raft with Surface Tension: Weekly Science Activity

Blog Post

In this week's spotlight: a physics family science experiment that investigates the dynamics of surface tension. Surface tension may keep your soda from spilling over the cup when you fill it a bit too full, but can surface tension also be used to propel something? In this science activity, students build a small, lightweight raft and experiment to see how surface tension—and some dish soap—can help move it across the surface of water. Build a Bathtub Toy Raft Powered by… Read more

You probably use computer programs every day. Every time you use the internet, play a video game, or us a smartphone, you are using computer programs. Do you want to learn a little bit about computer programming, without the need to actually use a computer? In this fun activity, you will write a “program” – a set directions for a volunteer to find their way through a maze. Can you help them find their way through without crashing? Read more

Racing Drones: Does Practice Make You Faster?

Science Fair Project Idea

Scientific Method

Have you ever flown a drone? Did you find it easy the first time you tried? In this project, you will fly a drone through an obstacle course and measure how practice changes your performance. Will practice help you finish the course in less time? Try it out! Read more

Racing to Win That Checkered Flag: How Do Gases Help?

Science Fair Project Idea

Scientific Method

Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Radiant Radish Seeds

Science Fair Project Idea

Scientific Method

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more
