In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
