Science Fair Project Idea
thumbnail Have you ever had your mind set on a goal, like getting to the next level in a video game or getting an "A" on your math test, but no matter hard you work on it and how much time you spend, you just can't seem to reach that goal? How does this make you feel? Do you feel like jumping up and down and screaming? This would be an example of a response to feeling frustrated. How do other people respond to frustration? Do they cry or display aggressive behavior? Do boys respond differently than… Read more

Science Fair Project Idea
An electric current produces a magnetic field. You can take advantage of this fact to make a simple apparatus to test the electrical conductivity of various materials, including both solids and liquids. The detector consists of a coil of wire, with a magnetic compass inside it. You connect one end of the coil to a D-cell battery. The other end of the coil is connected to whatever material you are testing, and the material, in turn, is connected to the other end of the D-cell. In other… Read more

If you like playing electric guitar, this could be a cool project for you. Have you ever wondered how an electric guitar works? In this project you'll wind one or more of your own electric guitar pickups and test them out in an inexpensive electric guitar. How will the sound change with the number of turns you use in the coil? Or with the strength of the magnets you use? Read more

thumbnail Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! 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 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 Do you like playing with squishy play dough or modeling clay? Wouldn't it be cool if you could add lights, sound, or even motion to your play dough creations? In this science project, you will make play dough that conducts electricity, which will allow you to connect lights, motors, and buzzers! This science project is the first in a three-part series on "squishy circuits," which can all be done with the same materials. We recommend doing the science projects in order. Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability This science project requires a Squishy Circuits Kit and ingredients to make conductive and insulating play dough. See the Materials and Equipment list for details
Cost Low ($20 - $50)
Safety Ask for an adult's help when using the stove to make the conductive play dough. Never connect the battery pack's terminals directly to each other; this is called a short circuit and can make the batteries and wires get very hot. Do not connect the LEDs directly to the battery pack without using play dough; this will burn out the LEDs.

thumbnail Wouldn't it be nice to avoid those nasty electric shocks you get after you've walked around on carpet and then shake a friend's hand, or all those crazy flyaways you get after brushing your hair? These are caused by static electricity. In this science fair project, you will build a super-sensitive charge detector to investigate the positive and negative electric fields created by static electricity. The detector can sense invisible electric fields, so try this science fair project to avoid the… Read more

thumbnail It would be fun to have a friend robot that helps you create art, right? In this project you will create your own Art Bot, a robot with markers for legs that wobbles across a piece of paper, generating markings with its "feet" as it moves. The creature's motion comes from a spinning motor with an off-center weight, which causes the robot to vibrate. You can change the size and location of this weight, which will affect how the robot moves, and change how it draws. Then you get to decide which… Read more
