Design a Wearable Air Quality Index Monitor

Science Fair Project Idea

Engineering Design Process

You can look up information about local air pollution, such as the Air Quality Index (AQI), online or even get alerts on your phone. But what if you could wear a device that continuously monitors the air quality around you in real time, alerting you to unsafe levels? Such a device could alert a person with asthma when they need to go inside, let you know if smoke from a nearby wildfire is drifting in your direction, or signal when it is time to take a break on a hazy summer day. The Science… Read more

Bacterial Resistant Materials and the Best Disinfectant

Science Fair Project Idea

Scientific Method

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Developing Images with X-rays

Science Fair Project Idea

Scientific Method

You have probably had X-rays taken at the dentist's or doctor's office, but do you know how the X-ray images are made? Images made using X-rays, also called radiographs, are considered to be relatively safe to take, even though they are made using a small amount of 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 and X-rays. X-rays can travel… Read more

Natural Antimicrobial Agents

Science Fair Project Idea

Scientific Method

What do pneumonia, ear infections and strep throat have in common? When they are caused by bacteria (instead of viruses) they are treated by antibiotics. That sounds simple enough, right? You have probably had antibiotics several times in your life. You go to the doctor because you feel lousy, if he or she determines you have a bacterial infection you get a prescription for antibiotics, and within the first day or so you often start feeling much better. Unfortunately, there is a large… Read more

Sound Localization

Science Fair Project Idea

Scientific Method

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

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. Read more

Under Pressure: Does a Child's Blood Pressure Depend on His or Her Age?

Science Fair Project Idea

Scientific Method

Every time you go to the doctor's office, the nurse measures your blood pressure. But why does he or she do this? What does your blood pressure tell your doctor about your health? And what exactly is blood pressure? In this life science project, you will learn about blood pressure and what causes it. You will even learn how to take blood pressure readings. Once you learn this skill, you will test a population of children and determine if blood pressure depends upon a child's age. Read more

Hey, Do You C My Potatoes? Determining Vitamin C Amounts in Cooked Potatoes

Science Fair Project Idea

Scientific Method

As you know, vegetables not only taste good, but they are good for you. Many vegetables are a great source of vitamin C. Vitamin C is a water-soluble antioxidant that plays an important role in protecting the body from infection and disease. Humans do not make vitamin C on their own, so we must get it from dietary sources. Potatoes, like the ones shown in Figure 1, below, are one good source of vitamin C. Does cooking them affect how much vitamin C they have? In other words, if you boil a… Read more

Trace Your Ancient Ancestry Through DNA

Science Fair Project Idea

Scientific Method

Did you ever wonder about your ancient ancestors? Who they were? Where they came from? In this science project, you will investigate the secrets of your distant past as revealed by your DNA. In order to obtain a sample for DNA analysis, you will scrape a soft swab inside your mouth to collect cheek cells. The cheek cell sample will be sent to a lab for processing, and the results of the analysis will be sent to you. Based on the genetic markers in your DNA, the ancient clan that your… Read more

Zapping Yeast with X-rays

Science Fair Project Idea

Scientific Method

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. When the energy in X-rays encounters an object, it can… Read more
