Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners explore clouds and how they form.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.

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

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
