Isn't the human body incredible? From the complex systems that make it work to the numerous ways we're able to cure illnesses, there are so many fascinating subjects to study when it comes to human biology and health. Are you interested in subjects like how the body works, how best to keep it working, and how to cure everything from a common cough to cancer?

Try the annual Engineering Challenge from Science Buddies! Open to all students worldwide, a new challenge and prizes are announced every January. Explore the current challenge as well as ones from past years!
If you're like most people, you like listening to music. Have you ever wondered how your ears and your brain turn the sound waves out there in the world into the experience of music in your head? If you're interested in doing a project about how we hear, this is a good one for you. With this project, you'll do background research and make measurements to understand how the sensitivity of your own hearing varies with the pitch of the sound.

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available.
Over time, viruses evolve. Their evolution is influenced by both neutral drift, the natural mutation rate of the virus, and selective pressure from the hosts' immune systems. Scientists study a virus's genomic evolution—the changes at the nucleotide and amino acid level—to better understand how the virus is spreading and the clinical implications. You can use public databases and tools to do the same type of tracking and analysis of COVID-19 that scientists around the world do. …
If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults?
In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them!
It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.
What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach…
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…

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.

One strategy you may have heard suggested for dealing with the COVID-19 epidemic is to let nature take its course and let COVID-19 infect enough of the population for us to reach the herd immunity threshold. Does this make sense as a public health strategy? You can explore this question scientifically using SimPandemic, a free online tool for modeling infectious disease outbreaks.
Before you begin, you will need to know a bit about herd immunity. Herd immunity, sometimes called community…
Are you interested in things like prosthetic limbs and artificial joints that can help people with disease or injury to lead a normal life? Or maybe you're interested in sports medicine or physical therapy? Either way, this project could be a good match for you. Find out how the tension on the knee joint changes as a function of angle by building a simple mechanical model.
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…
