Science Fair Project Idea
thumbnail Cars that can drive themselves might sound like science-fiction, but they are a reality. Self-driving cars are cars that use sensors and computer programs to automatically drive on roads, without intervention from a human driver. However, the cars still have to follow all the same rules of the road as human drivers, including staying in the correct lane, obeying road signs and traffic lights, and avoiding obstacles like potholes or fallen tree limbs. In this project you will build a simplified… Read more

thumbnail If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Science Fair Project Idea
Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more

Science Fair Project Idea
thumbnail In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more

thumbnail Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more

thumbnail The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created humanlike hands used as artificial… Read more

thumbnail Following a simple black line seems pretty easy, right? But think about it; how do you know what is the line and what is not the line? What if you wanted a robot to follow that line? How would it know what you wanted it to follow? Robots can use simple techniques to sense their surroundings and change their behavior based on what they see. In this engineering project, you will build your own robot that will follow a path without using complicated electronics or programming. Read more

Time Required Average (6-10 days)
Prerequisites You should be familiar with, or be willing to learn how to wire circuits on a breadboard. A little soldering is necessary to complete this science project, so you should also be familiar with the procedure or be able to find a helpful friend or adult.
Material Availability Readily available. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety If you are using the coping saw to make the wheels, use caution and be sure to wear safety goggles. Some steps require soldering, which involves very high temperatures. Use caution when soldering and when using other building tools. An optional step involves a product that must used in an open area, following the manufacturer's directions.
