Science Fair Project Idea
thumbnail Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (or e-textiles for short) really exist. Instead of using hard surfaces for circuits (like what goes inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into clothing that you can wear to make the clothing do fun, interesting things like light up, respond to sound, or even serve medical purposes… Read more

Science Fair Project Idea
thumbnail Have you ever seen moths buzzing around bright lights at night? What about animals that always crawl into dark places, under rocks or furniture? This type of behavior is called phototaxis — movement toward (or away from) a light source. In this project you will build your own biologically inspired robot critter that mimics this behavior. Basing your design on the popular and simple BristleBot robot, you will make a robot with two light sensors for "eyes" and two motors that help it steer… Read more

Prerequisites Some familiarity with electronic circuits and using breadboards will be very helpful, though not required, for this project. Using a soldering iron is also helpful but a work-around is offered in the Procedure.
Material Availability This project requires certain parts from an electronics store or online retailer. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety If you use a soldering iron for this project remember that soldering irons get extremely hot and can cause burns if they touch your skin. They can also become a fire hazard if left unattended. Science Buddies recommends using lead-free solder, especially in homes with pets or small children.

thumbnail Have you ever had several different design ideas for a project and not known which one to try first? Engineers use computer models of real-world objects called simulations to help them make decisions before they start building prototypes. This helps them save time and money, so they do not have to physically build and test each design they come up with. In this project, you will use a free physics simulation program called VoxCAD. VoxCAD has been used for research at NASA, MIT, and other… Read more

Science Fair Project Idea
thumbnail The world's oceans are home to the most strange and amazing creatures. What do scientists know about these deep-sea animals and how can they study them easily? One way to learn about these animals in their homes is to use underwater robots. Underwater robots can record data that would be difficult for humans to gather. But what are robots and how are they made? In this robotics engineering project, you will discover what makes up a simple robot and build and test your own underwater robot. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability To build an underwater robot you will need a motor and a model boat propeller. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
Safety You will need glue and epoxy to waterproof the motor for the robot. Follow the instructions that come with the glue and epoxy and always work in a well-ventilated area. If you have a latex allergy, you will have to exercise great caution with the balloon and ask a volunteer to help you. Keep fingers away from the spinning propeller to prevent injury. Do not test the robot in saltwater.

thumbnail A singing monkey? An elderly couple doing the chicken dance? What kind of funny electronic cards do you like to email people? Feel free to dream up your coolest and funniest card ideas, because in this science project, you'll create your own animated greeting card with a simple-to-use programming language called Scratch. Scratch is a programming language that makes it easy to create interactive stories, games, music, and art. When the program you have written is complete, you can even share it… Read more

thumbnail Psychologists have long studied why people find certain faces more attractive than others. One interesting method used in this area of research is mixing several faces together to make a composite face. The composite face averages the input faces, so that small, non-symmetric features tend to get lost. In this human behavior science project, you will use an online tool to make composite faces, and determine how they compare to real faces in perceived attractiveness. Read more

thumbnail Have you ever heard of the NASA Mars rovers Spirit, Opportunity, and Curiosity? How about the "bomb squad" robots that police and the military use? These are places that are hard for us to reach (Mars), or dangerous for us to be near (explosives). Because the human operators are usually far away from the robot, driving one is different from driving a car. Operators rely on information sent back from the robot, including pictures and video. In this project, you will build your own simple… Read more

thumbnail Have you ever wanted to build your very own robot from scratch? BristleBots are a cheap, easy, and fun-to-build robot made from the head of a toothbrush, a battery, and a small motor. Once completed, they buzz along the top of a table like bugs. In this project, you will build assorted BristleBots with different types of toothbrushes and race them against each other. 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 If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Time Required Short (2-5 days)
Prerequisites You should be familiar with programming for LEGO Mindstorms to do this project.
Material Availability This project requires a LEGO Mindstorms EV3 kit (available from [# Link Name="Amazon.EV3" Value="HtmlAnchor" #]) or a LEGO Mindstorms NXT kit.
Cost Very High (over $150)
Safety Make sure your cable car string is securely attached to a heavy object (like a table or large chair) at both ends. The Mindstorms bricks are heavy, and could fall and damage your LEGOs or other objects if the string is not securely attached.
