Students "observe" an imaginary new planet in our galaxy from the relative distances of a ground-based telescope, the Hubble Telescope, and a fly-by mission. After recording their observations and discussing the differences, they compare their... (View More) observations to actual images of Pluto taken from the New Horizons spacecraft during its July 2015 fly-by. (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 an activity about albedo, which is a measurement of the reflectance of a planetary surface. Learners will classify areas on an image in terms of albedo values and then sketch their own portion of an image from space. These sketches are... (View More) assembled to view the larger image that the class or group has created. Note: See Related & Supplemental Resources (right side of this page) for a link to download the student pages of this activity. (View Less)

Learners will create their own models of lunar orbiters out of edible or non-edible materials. They determine what tools would be necessary to help us better understand the Moon and plan for a future lunar outpost. Then they incorporate these... (View More) elements into their models. NASA's Lunar Reconnaissance Orbiter is used as an example of a spacecraft armed with "eyes," "ears," and other tools for exploration. This activity is part of Explore! To the Moon and Beyond! - a resource developed specifically for use in libraries. (View Less)

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

Learners will compare and contrast images of Earth and Mars and then experiment with lenses to understand more about the instruments used to make the pictures. This is activity 1 of 9 in Mars and Earth: Science Learning Activities for After School.
