Making Jell-o Stronger

Science Fair Project Idea

Scientific Method

Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll… Read more

Making Math with Dough: Weekly Science Activity

Blog Post

In this week's spotlight: a math activity that turns playing with dough into an exploration of geometry. If you make a cube out of dough, you can measure the sides of the 3D object and multiple the length by width by height to find out the volume of the shape. If you gently and uniformly flatten (or squish) the object, you transform your original shape into a new shape with new dimensions. Does the volume change? In this family-friendly math activity, kids can have geometry fun with… Read more

Making Patterns with Rubik's Cube

Science Fair Project Idea

Scientific Method

This project challenges you to figure out how to make geometric patterns with Rubik's Cube. Leaving your cube in one of these positions makes it much more tempting to pick it up and 'fix' it. Can you figure out how to make a checkerboard, or a cube-within-a-cube? Can you make only the center piece a different color from the rest? Can you figure out how to solve the cube from these positions? Read more

March Madness Basketball Science Projects

Blog Post

As college basketball prepares for the March Madness spring championship, students can investigate basketball science and the math and physics behind hoops success. March Madness Sports Science Great hands-on sports science projects help students explore science, physics, and math principles at work in the sports they love to play and watch. When it comes to basketball and March Madness, students can bounce through physics experiments related to… Read more

Materials for Sound Barriers

Science Fair Project Idea

Scientific Method

What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than… Read more

Measuring the Surface Tension of Water

Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

Memory Mnemonics

Science Fair Project Idea

Scientific Method

Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words.

Mini Trebuchet Science

Blog Post

When you build your own mini trebuchet from craft materials, launching projectiles becomes a source of scientific exploration! Explore physics and engineering while you learn more about this medieval tool. In this week's family-friendly physics activity, kids bring a medieval siege tool to life when they build their own mini trebuchet. While similar in concept to a catapult—they both launch projectiles—a trebuchet differs from a catapult… Read more

Model How Environment and Genetics Change the Chances of Getting Cancer

Science Fair Project Idea

Scientific Method

What is cancer? How does it develop? Doctors and scientists have asked these questions for hundreds of years to understand cancer and find treatments. In this science project, you can investigate these questions too by building a simple model and exploring how environmental and genetic changes affect the development of cancer. Read more
