Breath of Life: Does Exercise Increase Vital Capacity?

Science Fair Project Idea

Scientific Method

How much air do you think you breathe in when you take a deep breath? Can you increase your lung capacity by exercising regularly? Do athletes have greater lung capacity than non-athletes? This project shows you how you can find out. Read more

Design a Game to Help Alzheimer's Patients

Science Fair Project Idea

Engineering Design Process

Alzheimer's disease and dementia affect millions of people around the globe. Can you design a "brain training" game that can help people keep their brains healthy as they age, and maybe one day help treat or even prevent diseases like Alzheimer's? Try this coding science project to find out! Read more

Yeast Busters: Stopping Fungus in its Tracks with Antifungal Medicines

Science Fair Project Idea

Scientific Method

Have you ever wondered how antibiotics and other medicines are able to stop dangerous infections? How do such medications kill microorganisms without in general harming the person the microorganisms are infecting? Because many different types of microorganisms can infect us, we have had to develop an amazing number of ways to deal with these harmful microbes. Fungal infections can be particularly dangerous, but we have developed many different antifungal medications that can usually deal with… Read more

When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

Tiny Titans: Can Silver Nanoparticles Neutralize E. coli Bacteria?

Science Fair Project Idea

Scientific Method

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… Read more

Smart Medicine Cabinet: Build a Sensor That Reminds Patients When to Take Medication

Science Fair Project Idea

Scientific Method

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

How Does Your Eardrum Work?

Science Fair Project Idea

Scientific Method

Eardrums are membranes inside your ears that vibrate when sound waves hit them. These vibrations are converted into electrical signals and sent to your brain, which allows you to hear sound. The frequency response of your eardrum, or the range of frequencies that will cause it to vibrate, determines your hearing range. Typical human hearing ranges from about 20 Hz up to 20,000 Hz, although the ability to hear high frequencies typically degrades as you get older. Some other animals can… Read more

Disinfectants

Science Fair Project Idea

Scientific Method

Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare… Read more

Fear Factor: Using Pulse Rate to Measure Emotion

Science Fair Project Idea

Scientific Method

Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? Read more

Pretty Packaging: Can Attractive Packaging Lead to Healthier Eating?

Science Fair Project Idea

Scientific Method

Have you ever bought or tried something new, just because of the way it looked, or the nice box that it came in? On your birthday, which present do you pick to open first? The one that looks big and colorful and exciting or the one that is wrapped in old tissue paper? The way that something is packaged and wrapped often advertises what is inside. But can attractive, exciting packaging convince you to try something that might not be very exciting, but is, perhaps, something that is good for you?… Read more
