This reading was written by me for high school students to learn about climate change. The writing is at about a 6th grade level and is accessible to most high school students independently. There is space in the margins for students to annotate and make notes as they read and there are text dependent questions at the end to check for understanding. The reading covers what carbon is, what the carbon cycle is and how humans are disrupting the carbon cycle and causing global warming. This is a great reading to introduce your students to this relevant topic!
