• This interactive tool shows how different variables such as biosphere integrity, land use, and biochemical flows have changed from 1900 to 2009. 
• Students will learn that all of Earth's processes are interconnected, meaning a change to one process will affect the other parts of the Earth system. 

Positives

• The visual nature of this tool will help students to see how the factors' risk levels have changed over time.
• The information in the sidebar is helpful and interesting.
• The resource includes glossary terms that teachers could teach students before the lesson.

Additional Prerequisites

• Students will need access to a device if they are doing this in groups or individually.
• The resource uses data from 1900 to 2009. This resource has more current data, which is sorted by country.
• Students may be unfamiliar with some of the factors. Teachers may want to go over important terms before the lesson.

Differentiation

• Students could record the year when each of the factors moved outside of the safe conditions range and then make a visual representation of the data using a graph or chart.
• Earth science classes could discuss how each of the processes impacts other processes. 
• Other resources on this topic include this video on the human impact on Earth's systems, this Khan Academy video on the effects of agricultural practices, and this PBS video on understanding the atmosphere.
