Project Idea
thumbnail We rely heavily on our senses to tell us about our environment. But in addition to the senses of touch, smell, taste, hearing, and sight, some animals are able to sense Earth's magnetic field. Migratory turtles and birds use this sense to guide them on long journeys. Homing pigeons use it to find their way home. New research suggests that large mammals, such as cows and deer, may also have the ability to sense the direction of magnetic north. In this animal behavior science project, you will… Read more

thumbnail Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes! In this music science fair project, you'll investigate the different instruments composers have used to imitate or create impressions of bird songs and bird calls. Read more

Project Idea
thumbnail 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.

thumbnail Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more

thumbnail If you were leaving home for a long walk, how far would you go? One mile, 5 miles, 10 miles? How about 550 miles?! That's a long way, but some wolves have been known to travel that far when they are leaving their packs in search of a mate so they can form their own pack. But is that how far wolves normally travel? Try this wild wolf tracking science fair project to find out! Read more

Do you love to listen to your MP3 player while you're exercising, or listen to songs on the Internet? The relatively recent development of MP3 technology has made it possible to take a stack of CD's and store them on a device no bigger than a deck of cards. How does the MP3 format squeeze all those CD's down so well, and can it go too far? Try this music science fair project to find out! Read more

How do you figure out how to get places? Do you ask for directions, look at a map, or consult a compass? There are many ways for people to figure out how to travel from one place to another, but how do other animals do it? In this science fair project, you'll use real data, collected by biologists, to figure out how migratory birds manage to navigate more than 2,000 miles from their breeding grounds to their wintering grounds.
