Science Fair Project Idea
thumbnail Science Buddies has several fun robotics projects, like the and , where you use arts and crafts materials, like plastic cups or foam board to make the body of a robot. Have you ever wanted to design a more-advanced, sturdier, or fancier looking robot? Then computer-aided design (CAD) and 3D printing might be for you; both are simpler than you think! The directions on this page will give you an introduction to these technologies so you can design and print your own robot. Figure 1, below,… Read more

Science Fair Project Idea
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

- Less Details
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.
Science Fair Project Idea
thumbnail Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process. Read more

thumbnail Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking. Read more

Safety Adult supervision recommended. The oven is designed to cook food or boil water, so use proper caution to avoid burning yourself. Also be careful with the utility knife when cutting cardboard.
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

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.
Science Fair Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Material Availability This science project requires a kit available from the Science Buddies store. See the Materials and Equipment list for details. Estimated project time includes shipping.
Cost Average ($40 - $80)
Safety Never launch projectiles at people or animals. Be careful not to get your fingers caught in the moving parts of the catapult.
Science Fair Project Idea
thumbnail Do you like drawing or painting? What if you could build a robot friend that creates its own art? In this project you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you have wanted to try building your own robot, this is a great place to start! Read more

Science Fair Project Idea
thumbnail Do you realize that you are constantly bombarded by particles? You do not feel them, you cannot see, hear, or smell them, but they are always there! These particles — collectively called background radiation — might even travel through you without ever interacting with the molecules in your body. In this science project, you will build your own cloud chamber to prove the existence of background radiation. You will then use your cloud chamber to determine if the background… Read more
