This is an activity designed to develop a working definition of life. Learners will conduct a simple experiment, looking for signs of life in three different "soil" samples. The experiment introduces children to the difficulty that scientists face... (View More) in defining life. By observing the soil samples, participants try to determine if any contain signs of life and work to identify, refine, and create a set of characteristics that may be used to identify living versus nonliving things. The activity concludes with the development of a group definition of life. This group definition will be referred to in subsequent activities. It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 1 in Explore: Life on Mars? that was developed specifically for use in libraries.

This is a set of two improv-style activites that encourage participants to participate in learning about living and nonliving things. Learners will get to know each other through an icebreaker activity and state their ideas and previous experience... (View More) with living versus nonliving things. This will help prepare them to explore how scientists define and look for life in worlds beyond our own. It also includes specific tips for effectively engaging girls in STEM. This is the icebreaker activity in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)

This activity focuses on how the search for life on Mars is portrayed in fiction and videos. Learners will consider depictions of Mars from science fiction books and video clips. As a group, children discuss what they know about Mars and compare... (View More) their ideas with the way Mars and imaginary martians are presented in the science fiction works. They then use what they’ve learned to create their own Mars Science Fiction “Movie Trailer” Zines. It is recommended that this activity is preceded by two or three of the previous activities in the series so that the children will already have an understanding of what life needs and how Mars compares to Earth. This activity may be extended to serve as a tween and/or teen science fiction book club. It also includes specific tips for effectively engaging girls in STEM. This is activity 7 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)

Learners will construct a mock-up of planetary surface rover. They begin by exploring the importance of engineering in our society and work as a team to build a prototype of the team’s rover using student science notebooks and team sketches as a... (View More) guide. 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, three Vocabulary Cards, and a Mini-Lesson. This is lesson 13 of the Mars Rover Celebration Unit, a six week long curriculum. (View Less)

This is a lesson about landing site selection. Learners will work in teams to determine a landing site for their Mars Rover that best relates to their scientific question. They use technology skills to research Gale Crater through an online... (View More) interactive module and learn about features of Mars through use of Google Earth Mars. 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, three Vocabulary Cards, and a Mini-Lesson. This is lesson 8 of the Mars Rover Celebration Unit, a six week long curriculum. (View Less)

This is an activity about the Moon's influence on Earth. Learners think like a scientist — with reasoning skills and a healthy amount of skepticism — to sort puzzle pieces containing statements about the Moon into two images. The "Far-out Far... (View More) Side" has incorrect statements about the Moon (urban myths), and "True-Blue Blue Moon" has true facts about the Moon’s influence on Earth and life. This activity is part of Explore! Marvel Moon. (View Less)

This is an activity about the tides. Learners discover how the Moon's gravitational pull causes the level of the ocean to rise and fall twice a day along most coastlines. Six children represent the oceans, solid Earth, Moon, and Sun and move their... (View More) bodies to show the interactions of these elements. They then consider what the Earth's tides might have been like if there were no Moon. They model the smaller tides that would be produced solely by the Sun. This activity is part of Explore! Marvel Moon. (View Less)

Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and... (View More) in orbit around the Sun (revolution) is related to the appearance of the sky over the course of the day and year. Next they model that if the Earth's tilt was not stabilized by Moon, Earth's axis would slowly wobble between straight up (0° tilt) to nearly on its side (80° tilt). The resulting seasonal extremes would be unfavorable for life. Note that this activity is appropriate for children who are able to explore the geometry of Sun-Earth-Moon relationships in three dimensions. This activity is part of Explore! Marvel Moon.

Learners explore Earth's rotation and the Moon's role in our 24-hour day, using their bodies to explore and model the Earth's daily motions in this kinethetic exploration. They relate the motion of the Earth about its axis (rotation) to the... (View More) appearance of the sky over the course of the day. Learners consider the role of the Moon in slowing Earth's rotation over time; if the Moon didn't exist, Earth might be spinning more quickly, giving us an eight-hour day!
