This is a lesson about the requirements for life on another planet. Learners will grow organisms in one of 12 classroom environments and identify common requirements (such as water, nutrients, and energy). They will also design a mission to identify... (View More) habitable places by searching for water, nutrients, and energy. A math extension explores measuring calories. Includes background reading for teachers, student pages, reflection questions, and blackline masters. This is activity 2 of 5 in Astrobiology in your Classroom: Life on Earth..and Elsewhere?

This is a lesson about the field of astrobiology, the study of life in the universe, and ice as a preservative for evidence of life. Learners will consider the relationship between ice and life as they investigate the conditions required for life to... (View More) exist and sustain itself. They will study the impact of freezing on microbes and life processes and will learn about extremophiles, organisms that live in extreme conditions. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 8 of 12 in the unit, Exploring Ice in the Solar System. (View Less)
