Can You See Beyond the Rainbow?
There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.

Why Is the Sky Purple?
The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

What Causes Pressure?
Are you feeling the pressure? Let loose a little with a kinesthetic activity that models molecular motion in a closed space! The activity varies conditions such as volume and temperature and examines the effects on molecules.

If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Does Air Weigh Anything?
Can you feel the weight of the air on your shoulders? Your classes may not believe that air has weight. A straightforward experiment asks individuals to weigh a bottle before and after adding air. Their results may surprise them!

How Can Freezing Make Something Warmer?
Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

How Can Clouds Keep the Air Warmer?
Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Why Does it Get Colder on a Clear Night than a Cloudy Night?
Clouds are nature's insulator! A lab investigation asks learners to use an infrared thermometer to measure differences in infrared temperatures. They find that pointing the thermometer at a cloud has a much different result than pointing...

Do Cities Affect the Weather? (Making a Cloud in a Bottle)
The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...

Can Boiling Make Something Freeze?
Use boiling as an avenue for freezing. Young scholars watch as liquid nitrogen removes heat from the ingredients for ice cream. As this happens, the nitrogen boils and the ice cream freezes—all in the same container. A little science magic!
Colorado State University
What Is a "Convection Cell"?
Round and round in circles it goes! A hands-on activity has learners recreate a model of a convection cell. They watch as the difference in density of their materials creates a current.
Colorado State University
How Does the Earth Cool Itself Off?
Where does all the heat go when the sun goes down? An interesting lesson has learners explore this question by monitoring the infrared radiation emitted over time. They learn that hot spots cool more quickly that cooler spots.
Colorado State University
What Is a "Model"?
Model the transfer of energy during a typical 24-hour period. Young scholars use a game-like approach to learning the patterns of heat transfer through the day and night. Groups of four exchange different tokens as the energy...

Why Can Warm Air "Hold" More Moisture than Cold Air?—Vapor Pressure Exercise
Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...
Colorado State University
Why Do Hurricanes Go Counterclockwise in the Northern Hemisphere?
Test your class' coordination as they model the Coriolis Effect. Forming a large circle, learners move to the right as they try to toss a ball to the person across from them. The movement of the circle represents the rotation of the...
Colorado State University
Can Energy Be Created or Destroyed?
Energy doesn't come out of nowhere! An engaging lesson has learners investigate energy as it transforms from one type to another. They collect data to prove that energy is not lost as it changes.
