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 transfers...

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 "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.

Why Do Raindrops Sometimes Land Gently and Sometimes with a Splat?
A mouse can fall from large heights without injury! Air resistance is a large influence on small falling objects. In an exploratory lesson, young scholars build a raindrop bottle to compare the falling rate of different-sized objects.
Colorado State University
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!

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...

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...
Colorado State University
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...
Colorado State University
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.
Colorado State University
Why Do Clouds Form in the Afternoon?
The stability of the atmosphere changes on a daily basis. A kinesthetic lesson models how the stability of the air changes as it's warmed by the sun. Learners connect their models to the changing air currents and movement of warm and...
Colorado State University
Can Gravity Push Something Up?
How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...
Colorado State University
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.
Colorado State University
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!
Colorado State University
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.
Colorado State University
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...
Colorado State University
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.
Colorado State University
How Do Long and Short EM Waves Interact with the Earth's Atmosphere?
Things are about to heat up in your classroom! A kinesthetic lesson asks learners to play the part of the gases in the earth's atmosphere and interact with the sun's radiation. The focus is to learn the impact of the increasing...
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
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 stay...
Colorado State University
What Makes a Gas, a Greenhouse Gas?—The Carbon Dioxide Dance
Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to 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.
Colorado State University
What Is Energy?
Don't let the energy of your classroom falter! Explore the scientific definition of energy through play. A hands-on lesson focuses on the change of energy from one form to another.
Colorado State University
Why Are Clouds White?
Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

How Far Away Is Space?
Outer space may be a lot closer than you think! Science scholars model the layers of the atmosphere using transparencies to gain insight into the scale of space. The resource includes ideas to tailor the activity to the skill level of...
