Heart-related science fair projects educate students on anatomy, diseases, health and prevention.

On average, the adult human heart beats about 60 to 80 beats per minute, according to the American Heart Association. As it beats, this essential organ delivers oxygenated blood to the entire body every moment during a person's life. As a strong, core muscle of the body, the heart serves as an extremely educational subject for science fair projects for students of all ages.

  1. Heart Model

    • A relatively straightforward heart science fair project involves a model. A labeled heart model shows what this organ looks like and how it works. Students may purchase a model or can recreate one by drawing it on poster board or by shaping one out of clay, Styrofoam or papier mache. A carefully modeled replica would include parts like right and left pulmonary veins, right and left atriums, inferior and superior vena cavas, right and left ventricles, the aorta and many other valves. In addition to a model, students may also share a step-by-step drawing or video that shows how blood pumps into and out of the heart.

    Blood

    • A science project on blood serves as an important educational opportunity for students. The heart constantly pumps blood and at any given time, the human body has about six quarts of it running through veins and organs. Students can fill clear quart-sized milk jugs with red juice to show the amount of blood in the body. Then, they can prepare a coordinating poster that relates interesting blood facts, such as the time it takes blood to circulate once through the body or how many miles it "travels" in one year.

    Effects on Heart Rate

    • In this project, students can relate facts on what makes the heart rate increase and decrease throughout the day and why exercise is critical to maintaining a healthy heart. Physical activity increases the heart rate, and sedentary activities decrease the heart rate. Students can track heart rates on various activities for several weeks and then prepare a chart on poster board to illustrate averages. They can also include a target heart rate chart to show what the healthy heart rate range is for various age groups.

    Diseases and Conditions

    • To increase awareness and to promote healthy living, students can prepare a project that discusses various heart-related diseases and conditions. For example, students can create a poster that provides a step-by-step illustration of what happens to the heart during a heart attack. In another project, students can discuss another heart-related concern, high blood pressure. This project can explain what blood pressure is, why high or extremely low blood pressure can cause problems and how individuals can control it. With the help of a school nurse, this project can also include an electronic blood pressure machine for students to find out their readings.
