Through this set of lessons, students learn about the impacts of water shortages due to drought, make connections to climate patterns, and explore community resiliency solutions. The lessons engage students in evaluating solutions for a particular case study community. Students will need to do additional research on solutions, but by the end of the lesson, students will be able to articulate how drought, although a localized problem, has far-reaching impacts, and to suggest solutions to a problem that is projected to intensify as the climate continues to change.

This unit allows students to investigate past changes in Earth's climate. Students first explore relationships in climate data such as temperature, solar radiation, carbon dioxide, and biodiversity. They then investigate solar radiation in more depth to learn about changes over time such as seasonal shifts. Students then learn about mechanisms for exploring past changes in Earth's climate such as ice cores, tree rings, fossil records, etc. Finally, students tie all these together by considering the feedbacks throughout the Earth system and reviewing an article on a past mass extinction event.
