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 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 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)

This paper model shows the orbit of Comet ISON (late 2013) with respect to the innermost planets of the solar system. After reading background information about comets - how they form and where they come from - students cut out and tape together the... (View More) pieces of the model provided to show its orbital pathway (a single page of parts that can be assembled using just scissors and adhesive).
