Science Fair Project Idea
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

Prerequisites You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you). You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator.
Material Availability A kit containing all the specialty items needed for this project is available from the [# Link Name="Elec_p051.6" Value="HtmlAnchor" #].
Cost Low ($20 - $50)
Safety Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.
Science Fair Project Idea
thumbnail The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Science Fair Project Idea
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

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.
Science Fair Project Idea
thumbnail When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more

Science Fair Project Idea
thumbnail In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals can't rely on sight. Did you know that you can also build a robot that uses whiskers to find its way around? This science project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more
