Brushbots are a simple, fun type of robot that you can build out of arts and crafts materials. They are easy to build and you do not need any previous experience with robotics. You can build them yourself, build two robots with a friend and race them against each other, or even make them sumo wrestle! Go to the Materials section to see what parts you need to build a brushbot, and see the instructions for a step-by-step guide on how to build one. Read more

Here is a riddle for you: I am everywhere but you don't see me—what am I? The answer is: air! It is all around us, but it is usually invisible. We can, however, see the effect air has—for example when wind is moving tree branches. Air can move gently to create a nice breeze or turn into a wild and destructive hurricane. Not only can wind move objects with air, you can do it, too—as long as the objects are not too heavy! You can, for example blow on something—or you can… Read more

Coke® & Mentos® - Exploring Explosive Chemistry!

Science Fair Project Idea

Scientific Method

You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

Explore the Mixing Behavior of Liquids

Science Fair Project Idea

Scientific Method

Have you ever wondered why some liquids mix together easily, like when you mix different juices to make a fruit punch, while others do not mix at all, like oil and water? What happens to liquids when they are mixed depends on their mixing behavior. Some liquids blend, whereas others form separate layers. If you do it right, you can even stack liquids on top of each other just like solid objects! Want to see for yourself? In this science project, you will investigate the mixing behavior of… Read more

NGSS Performance Expectations:

3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants, respectively.

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more

Have you ever wondered what happens to the heart as we exercise intensely? How does its beating change? A doctor can figure this out by using a tool called a stethoscope, which is a long, thin plastic tube that has a small disc on one end and earpieces on the other end. In this activity, you will make a homemade stethoscope and use it to measure peoples' heart rates at rest and after exercising. Read more
