Science Fair Project Idea
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.

Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal. Read more

Time Required Long (2-4 weeks)
Prerequisites Provide a brief description of requirements: Since this project involves studying bats in their native environment, you should start this project only if you are confident you have bats in your neighborhood. Ask your science teacher if there are local bats that you can observe.
Material Availability You will need to purchase a bat detector for this science fair project. See the Materials & Equipment section for more details on where to purchase one.
Cost Average ($50 - $100)
Safety For this science fair project, you will be listening to bats as they fly near you. You will not be touching them or disturbing them in any way, so there are no safety issues. However, if you do see a bat on the ground, do not touch it because bats can carry dangerous diseases.

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

When is an animal considered endangered? When will it become extinct? What happens when a population has reached the limits of its resources? What happens to a population when a habitat changes? These are some of the questions population biologists try to answer. They use population models, created from math equations, to predict what will happen to a population over time. If you want to see how modeling is done and make some predictions of your own, you certainly won't need a crystal… Read more

Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working on making even more… Read more

Time Required Very Long (1+ months)
Prerequisites Having used a voltmeter/multimeter before is helpful, but not required.
Material Availability The microbial fuel cell kit needs to be special ordered from the [# Link Name="Elec_p071.7" Value="HtmlAnchor" #].
Cost Average ($50 - $100)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics, power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when in contact with electronics.

If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on… Read more

DNA is the "instruction manual" for the successful growth of a living thing, from a single cell to a mature adult. When the DNA of an organism is somehow damaged, it can have an impact on the organism's development over time. In this plant science fair project, you will track how irradiation (exposure to radiation) of radish seeds affects germination (sprouting of a seedling from a seed). Read more

Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching muscles, use exothermic reactions to produce a low level of heat that lasts for an extended period of time. Exothermic reactions change chemical energy into heat energy. In this chemistry science fair project, you will use heat packs to study the heat-generating… Read more

Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired. Read more

Have you ever heard the expression "a canary in a coal mine"? In the 1900's and earlier, coal miners brought canaries with them into the mines to act as early warning signals. The canaries were very sensitive to low levels of dangerous gases, so if the birds stopped singing, or got sick, then the miners knew to leave immediately, even if they felt fine. As it turns out, our froggy friends are also very helpful at signaling problems, not in mines, but in and around bodies of water. Try this… Read more
