Science Fair Project Idea
If you want to get your friend's attention at a crowded sporting event with lots of people cheering, you need to shout. If you're trying to do the same thing in a quiet library, a whisper works. The detection limit for each of our senses depends on the amount of "background" stimulation that is already present. This project uses an LED control circuit to investigate detection of changes in light levels. Read more

Up, up, and away! If you have ever made a wish and blown the fluff of a dandelion, you have witnessed how some plants are adapted to spreading their seeds using the wind. The tiny, furry parachute allows the seeds to be picked up by the wind and to be carried far away from their parent plant. In this experiment, you will make models of seeds and fruit to investigate dispersal by wind and to evaluate the relationship between the structure of the seed and its ability to be dispersed by the… Read more

Do you think it is possible to build a robot you can steer, without programming a computer to tell the robot what to do? Believe it or not, it is! In this engineering project, you will build a robot using a simple electronic circuit that steers the robot left or right to make it follow a bright light. Then you will make some adjustments to the robot to see if you can improve its steering. How well will you be able to control your robot? Read more

Science Fair Project Idea
Just one sheet of paper can lead to a whole lot of fun. How? Paper planes! All you have to know is how to fold and you can have a simple plane in a matter of minutes! But what design should you use to build the best plane? In this aerodynamics science project, you will change the basic design of a paper plane and see how this affects its flight. Specifically, you will increase how much drag the plane experiences and see if this changes how far the paper plane flies. There is a lot of cool… Read more

Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! Read more

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more
