Science Fair Project Idea
Have you ever wondered how X-rays affect living organisms? You have probably had X-rays taken at the dentist's or doctor's office. These X-rays are considered to be relatively safe, but every X-ray exposes a person to some radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation. [[ Video [] [] Video ]] When the… Read more

thumbnail When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

Time Required Long (2-4 weeks)
Prerequisites A basic understanding of radiation and [# ProjectGuide Name="Advanced.AnIntroductiontoRadiationSafety" Value="HtmlAnchor" HtmlText="radiation safety" #] is necessary before starting this science project.
Material Availability Many of the items for this science project, including the x-ray tube, need to be specially ordered. See the Materials & Equipment section for more details.
Cost Very High (over $150)
Safety A good understanding of [# ProjectGuide Name="Advanced.AnIntroductiontoRadiationSafety" Value="HtmlAnchor" HtmlText="radiation safety" #], proper radiation shielding materials, and supervision by an adult are required for this science project. The X-ray machine must be operated in a properly shielded place away from passersby. The X-ray machine requires a high voltage power supply; the output from the voltage supply can be deadly if mishandled.

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

thumbnail Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more

Watching fish swim around a tank is not only a soothing activity, but (along with learning how to care for the aquarium inhabitants) it is also a good introduction to ichthyology, the study of fish. But having pet fish doesn't have to be a passive hobby; you can put those fish to work by helping to grow food for you and your family. How? By designing and building an aquaponics system. Aquaponics combines hydroponics with aquaculture. Hydroponics is the science of growing plants without… Read more

thumbnail Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS) is equipped with its own HAM radio station. The allows astronauts, cosmonauts, and space mission specialists from different nations who are on board the space station to talk to people back home on Earth. Anyone with an amateur radio license is welcome to try… Read more

Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005) Read more

thumbnail Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more

thumbnail In our , we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as shown in Figure 1: [[… Read more
