This is a set of three activities about how scientists study other worlds. Learners will explore and compare the features of Mars and Earth, discuss what the features suggest about the history of Mars, and create a model to help them understand how... (View More) scientists view other worlds. The activities help to show why scientists are interested in exploring Mars for evidence of past life, and address the question: "Why are we searching for life on Mars?" It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 4 in Explore: Life on Mars? that was developed specifically for use in libraries.

This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More) comparing conditions on Earth and Mars, and then discuss ways in which organisms may protect themselves from UV radiation. They will then take part in a Mars Creature Challenge, where they will change their creature to help it survive harsh UV conditions — like on Mars. They will then test their Mars creatures by subjecting them to different environmental conditions to see how well they "survive" in a martian environment. This investigation will explore shelter and protection as one of life’s requirements and how Earth’s atmosphere protects life from harmful UV radiation. It also includes specific tips for effectively engaging girls in STEM. This is activity 5 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)

This activity focuses on the relationship between science of looking for life and the tools, on vehicles such as the Mars Rover, that make it possible. Learners will create their own models of a Mars rover. They determine what tools would be... (View More) necessary to help them better understand Mars (and something about life on Mars/its habitability). Then they work in teams to complete a design challenge where they incorporate these elements into their models, which must successfully complete a task. Teams may also work together to create a large-scale, lobby-sized version that may be put on display in the library to engage their community. The activity also includes specific tips for effectively engaging girls in STEM. This is activity 6 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)

This is a lesson about how to answer a scientific or engineering question. Learners will refine the scientific question they generated in Lesson 5 so that it can be answered by data and/or modeling, brainstorm possible solutions for the scientific... (View More) question chosen, determine reasonableness of solutions, use concept maps to enhance meaningful learning. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, two Vocabulary Cards, and a concept map supplement. This is lesson 6 of the Mars Rover Celebration Unit, a six week long curriculum. (View Less)

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) eukaryotic, bacterial, and archaeal domains. Topics in astrobiology are explored through projects, vocabulary reinforcement, and drawing assignments. Includes teacher notes, learning objectives, and assessment of prior knowledge and preconceptions. This is Lesson 1 in Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities. (View Less)

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)
