Human Biology & Health Project Ideas

Project Idea
thumbnail 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. Read more
HumBio_p006
+ More Details
- Less Details
Time Required Long (2-4 weeks)
Prerequisites To do this project, you should be handy with basic woodworking tools
Material Availability Specialty item (guitar string tuning mechanism)
Cost Average ($50 - $100)
Safety Adult supervision required (power tools used for assembly)
Project Idea
thumbnail Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

- Less Details
Time Required Short (2-5 days)
Prerequisites You will need access to an outside area with a clear view of the horizon and the zenith.
Material Availability Readily available
Cost Very Low (under $20)
Safety No issues
Project Idea
thumbnail 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
HumBio_p030
+ More Details
- Less Details
Time Required Long (2-4 weeks)
Prerequisites You will need to have a doctor, nurse, or other trained medical personnel teach you how to take blood pressure readings using a manual sphygmomanometer.
Material Availability You will need to purchase a manual sphygmomanometer with a child's cuff and a stethoscope. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Use the blood pressure cuff as directed. Adult supervision is recommended.
Project Idea
thumbnail Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology science fair project, you'll explore whether or not peppermint influences scores on different types of tests. Read more
HumBio_p027
+ More Details
- Less Details
Time Required Long (2-4 weeks)
Prerequisites An introduction to statistics.
Material Availability All volunteers must have access to a personal computer with Internet access.
Cost Very Low (under $20)
Safety No issues
Project Idea
thumbnail Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars, glucose and sucrose, in different foods and investigate how sucrose is converted into glucose with the help of an… Read more
HumBio_p035
+ More Details
- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability The invertase for this science project needs to be specially ordered. See the Materials and Equipment section for more details.
Cost Low ($20 - $50)
Safety No issues
Project Idea
thumbnail 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. Watch… Read more
HumBio_p034

Time Required Long (2-4 weeks)
Prerequisites Basic understanding of radiation and making pictures using film.
Material Availability See How to Build an X-ray Machine for a detailed list of materials that will need to be ordered.
Cost Very High (over $150)
Safety See Introduction to Radiation and Radiation Safety for safety information.
