Catch Your Breath: Build a Spirometer and Measure your Lung Capacity
Source Institutions
In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

How can Clouds Help Keep the Air Warmer?
Source Institutions
In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Test Your Lung Power
Source Institutions
In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

Dust Catchers
Source Institutions
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

Lung Capacity
Source Institutions
This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Breathing Room
Source Institutions
In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

Build a Lung
Source Institutions
Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Go with the Flow
Source Institutions
In this activity, learners discover how hard their hearts work to pump blood.

Bronx Cheer Bulb
Source Institutions
In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

Fungus Among Us
Source Institutions
In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

Space Stations: Measure Up!
Source Institutions
In this activity, learners work in pairs to measure each other's ankles with lengths of string.

Have a Heart
Source Institutions
Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.
