This student activity guide is complete with data tables for observations and analysis questions for processing what was observed. There is an accompanying lecture series, Changing Planet: Past, Present, Future that can be used with high school or college biology classes.

Pros

• A high-quality lecture series is available in video form for you to use in a flipped classroom scenario
• Well-organized student activity sheets walk lab groups through the setup and observation process
• Adaptable to Common Core standards for literacy in science

Cons

• The teacher activity notes are helpful, but do not provide step-by-step instructions for constructing the column; you will need to refer to the student activity page for materials and activity directions
