Science Fair Project Idea
Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

Time Required Average (6-10 days)
Prerequisites To do this science project, you must live in an area where you can receive at least one strong AM radio station. You can check for this with a car or portable radio.
Material Availability Specific circuit items are required. A Science Buddies kit is available for your convenience. See the Materials and Equipment list for details
Cost Average ($40 - $80)
Safety Never operate your crystal radio during a thunderstorm. When not in use, always disconnect your antenna from the radio circuit, and connect it directly to the ground rod. Be sure to wear safety goggles when installing the ground rod, especially if you are using a metal hammer. An adult's help might be necessary for some steps in the Procedure.

Don't you just love listening to music? In the 1980s, people listened to music on the Sony® Walkman®. Now, people listen to their favorite tunes on MP3 players and on their Apple® iPhonesTM. But listening to music on devices actually started in the late 1800s and early 1900s. In those days, people would gather around their phonograph to listen to their favorite tunes—people were just as amazed with the phonograph as you would be to handle an iPhone. In this physics science… Read more

Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? A bottle is actually what is called a closed-end air column. Clarinets and some organ pipes are examples of musical instruments of this type. In this science project, you will use bottles to investigate how the length of a closed-end air column affects the pitch of the note that it makes. All you need are some bottles, water, a ruler, and a chromatic tuner. Read more

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

Solar cells are devices that can be used as a source of power when there is light shining on them, but they stop producing energy when they are not in the light. One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor. The capacitor stores the energy as an electric field, which can be tapped into at any time, in or out of light. In this electronics science project, you will use parts of a solar car to experiment with the energy storage… Read more
