Measles is one of the most contagious viruses in the world, but there are differences in how the virus can spread within communities. Some communities may be able to prevent the disease from spreading, whereas others could experience a rapidly spreading, overwhelming outbreak. How does immunity and vaccination in a population of people affect how measles spreads? To answer this, this science project can be completed using the Measles: Defeating a Debilitating Virus Notebook with…

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for
more than just making calls though. They use them for texting and searching the Internet, too. But some health groups
are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics
science project, you will investigate how much radiation your cell phone emits when used…

Ozone in the stratosphere protects the earth by absorbing harmful ultraviolet radiation from the sun. However, when ozone occurs in the troposphere, i.e., the air that we breathe, it is harmful to health. In this project you can use data from EPA monitoring stations to analyze the weather/climate conditions that can lead to harmful ozone levels.

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!

Have you ever heard that nanoparticles can kill bacteria? You may have even seen some consumer products advertise that they contain antibacterial nanoparticles. A nanometer is one billionth of a meter long. Nanoparticles are usually just a few nanometers in diameter — really, really tiny! So how can something that small kill bacteria which are approximately 700 - 1400 nanometers across? Are they really effective? In this science project you will grow some E. coli bacteria and…

Have you ever noticed that your heart beats faster when you’re nervous before a big event? How and when does your heart rate slow down back to normal? In this science experiment, you will see if you can use different stress reduction techniques (meditation, yoga, breathing techniques) to determine which type works best for different kinds and intensities of stressors (physical or mental). You can also record other physiological measures, such as blood oxygen and blood pressure, to see how…

Have you heard the term windchill used before? Maybe on the TV weather forecast? The windchill factor describes what happens to an object (like your body) when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body temperature (which, in extreme cases, can lead to death). In this science fair project, you will use a device to measure wind speed (an…

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out.
