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

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

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

When Your Sniffer Snoozes, You've Got Olfactory Fatigue

Science Fair Project Idea

Scientific Method

The holidays are a wonderful time, when lots of good foods and good smells come from the kitchen. But have you noticed that if you stay in the kitchen awhile, you no longer notice the delicious smells? Don't worry! Your nose is not broken, you are just experiencing olfactory fatigue—basically, that's when your nose takes a nap. But what is behind olfactory fatigue and what happens when you experience it? Does a person's sense of smell "get tired" in the same way for different smells? Put… Read more

Breathing occurs effortlessly, but did you ever wonder how we breathe? In this lesson, students will make a model to discover how air effortlessly flows in and out of our lungs. Next, students will compare lung breathing to other ways of breathing to discover reasons why humans might have developed lungs. Remote learning: This lesson plan can be conducted remotely. Students can work individually and independently during the Explore section guided by the video and the Student Worksheet. A set… Read more
