Science Fair Project Idea
thumbnail Are you fascinated by radioactivity and the emission of particles caused by the disintegration of an atom? This science project enables you to observe safely a spectacular display of radioactive decay. Following the instructions in the Procedure, you will be able to isolate a safe radioactive source and build a cloud chamber to watch the radioactive decay. Then you will use your cloud chamber to discover if a plastic lid can shield you from this type of radioactive decay particles. Read more

- Less Details
Time Required Average (6-10 days)
Prerequisites Basic understanding of, or willingness to study independently, the atomic model and what radiation is.
Material Availability Specialty items are required. See the Materials tab for details.
Cost Average ($50 - $100)
Safety

You will be working with radioactive material in this science project; it is completely safe as long as the simple safety instructions in the Procedure are followed.

This project uses isopropyl alcohol, a flammable product. Do not use it near an open flame or anything hot.

Dry ice is colder than regular ice and can damage your skin. Wear insulating gloves when handling it.

If you choose to take apart a smoke detector, be very careful when cutting through metal or plastic. Cut edges might be sharp. Adult help and supervision is required. Minor injury is possible.

thumbnail Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle? Read more

Science Fair Project Idea
thumbnail Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell (MFC). Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. As natural resources are being depleted, scientists' attention has shifted to pursuing alternative energy sources, such as MFCs, even more than before. A microbial fuel cell, also known as a biological fuel cell, is a device that can… Read more

Time Required Very Long (1+ months)
Prerequisites Previous experience using a voltmeter/multimeter is helpful, but not required. A basic knowledge of how to work with bacteria is also needed to complete this science fair project. Consult the [# ProjectGuide Name="Advanced.MicrobiologyTechniquesampTroubleshooting" Value="HtmlAnchor" HtmlText="Microbiology Techniques and Troubleshooting" #] guide for information on how to conduct microbiology experiments.
Material Availability The microbial fuel cell needs to be special ordered from the Science Buddies Store. Other specialty items, like the media to grow bacteria on, can be ordered from [# ProjectGuide Name="Advanced.ApprovedSuppliers" Value="HtmlAnchor" HtmlText="online vendors" #] such as [# Link Name="EnvSci_p016.5" Value="HtmlAnchor" HtmlText="Carolina Biological Supply Company" #].
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 or power plugs, or have their fibers dispersed in the air. Use sterile technique when growing the bacteria. Read the [# ProjectGuide Name="Advanced.MicroorganismsSafetyGuide" Value="HtmlAnchor" HtmlShortTitle="true" #] before starting any experiments. [# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC approval" #] may be necessary. Adult supervision is recommended.

Time Required Very Long (1+ months)
Prerequisites Having used a voltmeter/multimeter before is helpful, but not required.
Material Availability The microbial fuel cell needs to be special ordered from Science Buddies. See the Materials tab for details.
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.

thumbnail Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more

thumbnail Naval fighter pilots seem to defy physics each time they fly their jets off of an aircraft carrier. Normal runways are thousands of feet long so that airplanes can develop enough lift to fly. But a runway on an aircraft is much shorter. How can naval pilots get their fighter jets into the air without falling off the carrier into the ocean? Well, because they get a boost from a catapult! Sounds unbelievable? It's not, and you can find out more about catapult-assisted takeoff in this aerodynamics… Read more
