Science Fair Project Idea
thumbnail People often call cardiovascular disease a "silent killer." This disease sneaks up and causes damage, but patients don't realize it—until serious symptoms start. That is why physicians recommend keeping your cardiovascular system healthy. A healthy cardiovascular system gives us the energy and the stamina to do all of the things that we want to accomplish, such as do our best in school and perform well in sports. But what makes a cardiovascular system unhealthy, and what are the… Read more

thumbnail Did you know that your heart beats at different rates depending on what you're doing? The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science fair project will show you how to take your pulse and help you investigate which daily activities get your heart beating the fastest. Read more

thumbnail Doctors use many complicated tools to check the health of patients. But you can make some medical tools at home—like a stethoscope! A doctor uses a stethoscope to listen to a patient's heart. In this science project, you will make three of your own homemade stethoscopes and figure out which stethoscope design works best and why.

Science Fair Project Idea
thumbnail Over an average lifetime, the human heart beats more than 2.5 billion times, supplying blood to the entire body. When a person exercises, the heart has to work harder than usual. Have you ever wondered how quickly your heart beats when you exercise, or how long it takes to recover back to its normal rate after you are done exercising? Is the heart rate recovery time faster for people who get regular exercise compared to people who do not? Try out this science project to find out! Read more

thumbnail Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more

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

Science Fair Project Idea
Have you ever woken up in the middle of the night just not feeling well? Maybe your mom or dad gave you some medicine and you felt better after taking it. Medicine is a great tool in the fight against an illness, but medicine can be a poison if too much is taken. Similarly, household products can clean your home and make it smell great, but if eaten, can be poisonous. That is why most medicines and household products are stored in childproof containers. But are childproof containers really… Read more

thumbnail Have you ever been so cold sitting in your house in the winter that you feel icicles could grow off your nose and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner—but that costs money. Still, being cozy or cool doesn't have to cost a lot of money if you use a geothermal heat pump. In this project you will build a model… Read more

thumbnail The benefits of Western medicine have evolved tremendously, with a wealth of tests and medications to treat many conditions. But remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple… Read more
