Make a Communication Aid To Help People Show Their Feelings

Science Fair Project Idea

Engineering Design Process

Have you ever tried to communicate with a baby or toddler who cannot talk yet? What about another kid or an adult who cannot speak due to a medical condition? There are many ways we can communicate without speaking, like writing or using sign language. We can also use technology to help make it easier to communicate. In this project you will program your own communication aid to help someone who cannot speak show their emotions or simple messages. Read more

Make an Adaptive Switch

Science Fair Project Idea

Engineering Design Process

How could you send a text message without using your thumbs? What about typing on a keyboard or using a video game controller without using your fingers? Due to a variety of medical conditions like cerebral palsy or paralysis from an accident, some people might be unable to easily use their hands and fingers to push small buttons or use joysticks. However, they might be able to use their entire hand to push a single larger button or use another part of their body like their foot or even their… Read more

Measuring Concussion Risk in Football and Other Contact Sports

Science Fair Project Idea

Scientific Method

Playing sports can be a lot of fun, but some sports pose higher risks of concussions, or brain injuries resulting from collisions, especially in contact sports like football. Some coaches, teams, and players use new warning devices mounted on helmets that sound an alarm after the head receives a serious impact. This gives an advanced warning of concussion risk (possibly before any of the medical symptoms might appear), signaling that the player should stop playing and see a medical… 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

Motor Imagery Visualization's Impact on Fine Motor Skills for Space Flight

Science Fair Project Idea

Scientific Method

In this science experiment, you will model and test how visualization of a task can change the accuracy of your fine motor skill performance. You will use the small muscles in your hands to model how your body would perform on Earth versus a space launch. Read more

Now You See It, Now You Don't! Test Your Peripheral Vision

Science Fair Project Idea

Scientific Method

Peripheral vision is important in our everyday lives because it allows us to gather a visual sense of our surroundings—without it, we would see the world through "tunnel vision." The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do—from riding a bike, to dribbling a basketball, to reading a book—depends on peripheral vision. In this human biology science fair project, you will test… 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

Preventing Outbreaks with Herd Immunity

Lesson Plan Grade: 6th-12th

What is herd immunity, how is it achieved, and what impact does it have on outbreaks? Students will explore these questions and more in this lesson plan. They will then use SimPandemic, a free online tool, to model different levels of viral immunity in communities to understand how a population can reach the herd immunity threshold and the impacts that has on individuals and populations during a COVID-19 outbreak. Remote learning adaptation: This lesson plan can be conducted remotely. … Read more

NGSS Performance Expectations:

MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
HS-LS2-8. Evaluate evidence for the role of group behavior on individual and species' chances to survive and reproduce.

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

Sound Localization

Science Fair Project Idea

Scientific Method

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more
