Ninth Grade Human Biology & Health Science Projects (5 results)

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? If so, explore your interests by tackling one of the human biology and health projects from our collection.

Science Fair Project Idea
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

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 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
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

Science Fair Project Idea
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

Science Fair Project Idea
People have a variety of reasons to use heart rate monitors. For example, patients in a hospital might have stationary, bedside equipment monitor their heart rate and alert medical staff in case of an emergency. Somebody going for a run might wear a portable heart rate monitor to keep track of their workout intensity. Heart rate monitors are not all the same—their appearance and function will vary depending on the intended use. In this project you will design, build, and program your own… Read more

Time Required Average (6-10 days)
Prerequisites Familiarity with Arduino™ and assembling basic circuits (or a willingness to learn) will be needed for this project.
Material Availability Requires an Arduino and additional circuit parts. See Materials section for details.
Cost Average ($50 - $100)
Safety The device you build in this project can be used as a demonstration/proof of concept for a science or engineering fair. It should not be used to diagnose or treat medical conditions.
Science Fair Project Idea
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

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.
