Here students use data from the NOAA carbon dioxide monitoring sites, such as Mauna Loa, to graph the Keeling Curve for themselves on large sheets of paper. Each group graphs one year, and the graphs are joined at the end to reveal the overall upward trend. The explanation describes the carbon cycle and how human activities are leading to the overall trend of rising carbon dioxide.

This well-designed experiment compares CO2 impacts on salt water and fresh water. In a short demonstration, students examine how distilled water (i.e., pure water without any dissolved ions or compounds) and seawater are affected differently by increasing carbon dioxide in the air.

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of the chemistry behind this change and the consequences of ocean acidification. The video also addresses a misconception about how ocean acidification affects shelled organisms.

In this lab activity, students investigate how to prepare a biofuel source for conversion to a combustible product. The activity models how raw materials are refined to process liquid fuels.

In this interactive activity students will create a very simple climate model. They use worksheets, chips/tokens, and follow rules for heat exchange. The activity only models temperature but there are instructions for adaptations of the model, such as rule changes for an atmosphere with increased levels of CO2.

This activity allows students to demonstrate the thermal expansion of water for themselves using water bottles and straws. The discussion allows them to explore the connection between this concept and sea level rise due to climate change.

This activity includes two experiments that explore shadows and light and how mirrors can demonstrate how light travels.

In this short but effective demonstration/experiment, students investigate how thermal expansion of water might affect sea level.

Students participate in a demonstration to explore how clouds form and what conditions are necessary for cloud formation.

This activity from the Department of Energy provides background information about solar ovens and instructions on building a simple model solar cooker.
