In this worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.

This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

Students first learn about the complexities of Earth's climate system and the different factors contributing to Earth's energy balance. Then, students categorize the factors that influence climate as warming or cooling factors. Finally, students design art pieces to depict the science behind Earth's climate system and share these artistic creations with families and communities.

Students consider the ways their climate affects their region, by identifying a type of food unique to the region and selecting (and possibly cooking) a recipe that features that ingredient. Optional activities to make the food are also provided.

Children create a wind streamer out of common materials and use it to determine the wind's direction.

Students observe, sketch, and describe clouds on their own before learning to identify cloud types by comparing photos of different clouds to their sketches.

This interactive activity, in applet form, guides students through the motion of the sun and how they relate to seasons.

This activity covers the role that the oceans may play in climate change and how climate change may affect the oceans. It is lesson 8 in a nine-lesson module Visualizing and Understanding the Science of Climate Change.

For this lesson, the guiding Concept Question is: What is climate change and how does climate relate to greenhouse gas concentrations over time? This activity is the second lesson in a nine-lesson module 'Visualizing and Understanding the Science of Climate Change' produced by the International Year of Chemistry project (2011).

This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.
