Human Biology & Health Project Ideas

Science Fair Project Idea
thumbnail You are probably very familiar with the fact that over time, exercise changes your muscles, your lungs, your bones, and even your mindset; but did you know it has an immediate effect on your body's biochemistry? You can see this in the amount of glucose (a type of sugar your body uses for fuel) circulating in your blood. Blood glucose levels change as you exercise. For most people, this is not a big deal. But for top-level athletes in the middle of intense exercise (like a marathon), or for… Read more

- Less Details
Time Required Long (2-4 weeks)
Prerequisites Informed consent must be obtained from participants in this experiment (parental consent must be granted for minors). The experimental design (including consent forms) must be approved by your fair's Scientific Review Committee ([# ProjectGuide Name="Advanced.ScientificReviewCommitteeSRC" Value="HtmlAnchor" HtmlText="SRC" #]).
Material Availability A blood glucose monitoring system is required to do this science project. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Follow all safety precautions when using the blood glucose monitoring kit and when handling blood, as described in the Procedure. If somebody who has diabetes wants to participate in this science project, review the safety notes at the beginning of the Procedure before starting.
Science Fair 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

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)
Science Fair 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

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
Science Fair 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.
Science Fair Project Idea
thumbnail Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels)by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more
HumBio_p040

- Less Details
Time Required Average (6-10 days)
Prerequisites Some familiarity with electronic circuits and using breadboards would be helpful, though it is not required for this project. Completion of a basic chemistry class is also recommended before trying this project.
Material Availability A pump and other electronics parts must be specially ordered to do this project. See the Materials and Equipment list for details. Estimated project time includes shipping of specialty components.
Cost Average ($40 - $80)
Safety Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.
Science Fair 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

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
Science Fair 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

Science Fair Project Idea
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. [[ Video [] … Read more
