Wearable Limp Detection Device
Science Fair Project Idea
Engineering Design Process
Have you (or anyone you know) ever sprained an ankle or broken a leg? It might have taken some practice to walk again after recovering from an injury. Some people might even need to work with a physical therapist. In this project you will program a wearable device to recognize when someone is limping instead of walking normally.  Read more

What is a normal body temperature for humans? Have you heard people say it is 98.6°F or 37°C? You will find out for yourself if that is fact or fiction in this simple activity. Read more
What’s Your Ideal Walking Speed?
Science Fair Project Idea
Scientific Method
​​Walking may seem simple, but it is actually a carefully coordinated process involving balance, rhythm, and efficiency. The way we walk—our gait—changes depending on speed. At slower speeds, people tend to take shorter, more careful steps. At faster speeds, stride length usually increases and step frequency (cadence) rises to keep up. Biomechanics researchers study these patterns to understand how speed influences gait mechanics and stability, since walking is one of the most… 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
