A Magnetic Primer Designer

Science Fair Project Idea

Scientific Method

How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR. Read more

Old Salty: Does Age Affect the Ability to Detect Salt?

Science Fair Project Idea

Scientific Method

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat. Read more

Modeling the Human Cardiovascular System: The Factors That Affect Blood Flow Rate

Science Fair Project Idea

Scientific Method

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

Save a Life! Teach Hands-Only™ CPR

Science Fair Project Idea

Scientific Method

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach… Read more

Learning Your A, G, C's (and T, too)

Science Fair Project Idea

Scientific Method

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this new alphabet. Read more

Be Seen After Dark—What Clothes Keep You Safe?

Science Fair Project Idea

Scientific Method

Did you know that the most likely time to be struck and killed by a car in the United States is at dusk, dawn, or at night? In 2014, 3 out of every 4 pedestrian fatalities happened in these types of poor light conditions. Is there something you could do to decrease the chances you, your friends, and your family members are safer when walking or biking at night? Do you think the types of clothes that you wear could make a difference in how visible you are to drivers? Explore the science of… Read more

Are Childproof Containers Really Childproof?

Science Fair Project Idea

Scientific Method

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

Distracted Driver: Do Distractions Affect Driving Video Game Scores?

Science Fair Project Idea

Scientific Method

Have you ever tried rubbing your stomach and patting your head at the same time? What about doing your homework or studying for your math test while watching television? It is tough to focus on a task when you are distracted doing something else, isn't it? In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend.

Do Heavy Loads Shorten Your Steps?

Science Fair Project Idea

Scientific Method

You probably notice that when you carry something heavy—whether it’s a backpack filled with books, grocery bags, or a weighted vest—the way you walk changes. Your body adjusts in many ways to maintain balance, avoid fatigue, and reduce injury risk. One of these adjustments happens in your step length—that is, how far you move forward with each step. Biomechanical studies show that adding extra load (weight) often causes people to take shorter, more cautious steps. This… Read more

Should We Walk Like Penguins? How Age Affects Your Stride

Science Fair Project Idea

Scientific Method

Watch out for that ice! When winter weather makes sidewalks icy, many people slip and fall. One tip doctors give is to walk like a penguin. That means pointing your feet slightly outward, keeping your center of gravity over your feet, and taking short, careful steps. Research has shown that these changes in stride and posture help people stay stable and avoid falls. These tips are especially helpful for older adults, who are more at risk of falling due to a decline in their balance as they… Read more
