What do rocks and clocks have in common? Both keep track of time. Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away. Geologists use those radioactive isotopes to date volcanic ash or granite formations like the giant Half Dome in Yosemite National Park. Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. Does this sound abstract… Read more

Science Fair Project Idea
Electronic devices can be designed to detect dangerous fumes or other hazards, such as smoke or carbon monoxide. In this electronics project, you will build another potentially life-saving detector—a radon detector. Radon gas is radioactive and can pose a hazard to your health if you live in an area where it leaks from the ground. In this electronics science project, you will learn how to collect radon with an ordinary dusting cloth mounted on the intake of a fan, and then measure its… Read more

Time Required Very Long (1+ months)
Prerequisites Since the goal of this science project is to measure radon gas, you should have access to an area that has previously tested positive for radon with a commercial radon detection system. See the Experimental Procedure section for details. This is an advanced science project that will require creative problem solving on your part.
Material Availability While most of the parts for this science project are readily available, you might need to be creative about finding or making some of the parts.
Cost High ($100 - $150)
Safety Wear safety goggles when drilling and soldering. Adult supervision is recommended.

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

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.

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry, and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project,… Read more

You may know Lewis Carroll as the author of Alice in Wonderland, but did you know that in real life he was a mathematician who studied symbolic logic and logical reasoning? How can math help you solve Lewis Carroll's Logic Game? (Bogomolny, 2006) How are algorithms for solving the game Sudoku similar to solving a logic problem? (Hayes, 2006) For the super-advanced mathematical genius, try to evaluate currently available, logic-based computational tools, or design a better one!… Read more

Learning to play an instrument can be a lot of fun, especially when you can pretend to be a rock star as you learn! In this science fair project, you will study how your score in a music video game changes as you play and practice. You'll need a video game where you use a controller shaped like a musical instrument. Two examples include Guitar Hero and Rock Band, but there may be more! In these games, playing requires nothing more than a sense of the music's beat, and ridiculously fast fingers,… Read more

Do your parents like to garden? Then you might have a beautiful lawn surrounded by flowers, or a vegetable garden. Humans have been introducing plants to our landscapes for centuries, which has dramatically altered the natural habitat of many environments. Chances are, the landscape you live in is not a natural landscape. One movement is to restore these habitats by re-introducing native plants. Conduct a survey in your area looking for native and non-native plant species. You can take… Read more
