OverviewIn “Climate Science in Focus (Earth a System),” students will learn about the four Earth systems and how they are connected. Broken into eight days, these lessons require 58 minutes to complete. Designed around 9th grade Next Generation Science Standards, it is a unit easily adapted down for middle school or up for advanced high school classes. Teach the entire unit or pull out particular activities. This is lesson 1 of the unit.
Students will be able to:
1. Explain the Earth as a system of interconnected parts
2. Properly define and use Earth science vocabulary
The Earth consists of four systems: the atmosphere, hydrosphere, geosphere, and biosphere, which are interconnected. Changes to one part of the system can have consequences on the others. Changes to global or regional climate can be caused by changes in the sun's energy output or Earth's orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activity.
Water is essential for life on Earth. Relative water availability is a major factor in designating habitats for different living organisms. In the United States, things like agriculture and water rights are hot topics. Current models predict that average global temperatures are going to continue to rise even if regional climate changes remain complex and varied. These changes will have an impact on all of Earth's systems.
Studies have shown that climate change is driven not only by natural effects but also by human activities. Knowledge of the factors that affect climate, coupled with responsible management of natural resources, are required for sustaining these Earth systems. Long-term change can be anticipated using science-based predictive models, making science and engineering essential to understanding global climate change and its possible impacts.
National Parks can serve as benchmarks for climate science trends and effects over time because they are protected areas void of human influence. Understanding current climate trends will help set students up to be successful in interpreting and engaging in discussions about climate change, which will lead to informed decision making.Day 1- Earth as a System

Most of the materials for this unit are provided in the Stream Flow River Study Trunk or as downloadable files.
Video "Earth as a System"
Butcher paper/markers one set per group (Teacher provided)
Post-it notes (3 per student) (Teacher provided)
Distribute the DoNow: What is a system? Define and provide an example of a system. Diagram your system.
1. Distribute worksheet 1.1and have students complete pre-video questions on worksheet 1.1
2. Show the video "Earth as a System." Students should complete post-video questions on worksheet 1.1.
3. Monitor discussion and distribute butcher paper and markers for posters. Separate students into small groups, have students discuss what "Earth as a system" means?
4. Students should create an illustration that demonstrates, "Earth as a System." Be sure to include the 4 spheres and give at least one example of how humans are impacting/influencing each one.
5. Distribute post-it notes and instruct students on "gallery walk." Students should walk and view posters created by all groups and make 2 positive comments and 1 suggestion on each.
Distribute exit ticket—How do you view the Earth differently after today's activities?
