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)

This is a lesson about the characteristics necessary for life. Learners will identify the top candidates for life in the solar system by examining Habitability Cards, which discuss each planet and the six large moons in terms of water temperature,... (View More)

This is a lesson about the categorization of the three domains of life on Earth and how they relate to the study of astrobiology. Learners will explore, compare, discuss, and explain the basic differences between organisms assigned to the... (View More)

Learners will use the results of previous lessons in this guide to write a scientific proposal to explore another planet or moon in our solar system for signs of life. This proposal should predict the types of energy and nutrients available to... (View More)

Audience: Middle school

This is a lesson about the evidence for life on other planets. Learners will play a game to examine processes in cellular metabolism and explore both direct and indirect evidence for fingerprints of life. Includes teacher notes, learning objectives,... (View More)

This is a lesson about extremophiles and using DNA sequences to classify them. Learners will describe the characteristics of a newly discoverd thermophyllic organism and use the DNA sequence to place that organism in the phylogenetic tree of life.... (View More)

Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates in an aquarium in their classroom. For an optional... (View More)

Working in pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish... (View More)

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)

In this activity, student teams design small-scale physical models of hot and cold planets, (Venus and Mars), and learn that small scale models allow researchers to determine how much larger systems function. There is both a team challenge and... (View More)
