SOFIA Lithograph

This lithograph contains a photograph of the airborne observatory in flight and provides reference information regarding SOFIA's Mission, the telescope, and observatory operations.

Exploring the Earth as a Magnet

This is an activity about Earth's magnetosphere. Learners will use a magnet, simulating Earth's protective magnetosphere, and observe what occurs when iron filings, simulating the solar wind, blow past and encounter the magnet's field.

What is a Planet? Video

This classic video explains the history, debate and continuing discussion of the definition of a planet.

Connect the Spheres: Earth System Interactions

After making observations of their natural surroundings, students uncover the intricate relationships between the atmosphere, biosphere, geosphere and hydrosphere. This introductory lesson uses the 5E instructional model.

Light in Air Game

In this kinesthetic activity, students take on roles of either photons or gas molecules. Photons signal a change from visible light to infrared with a piece of folded construction paper, simulating absorption by the Earth's surface and reradiation to space.

Using Mathematical Models to Investigate Planetary Habitability: Activity A Finding a Mathematical Description of a Physical Relationship

In this activity, student teams learn about research design and design a controlled experiment exploring the relationship between a hypothetical planet, an energy source, and distance. They analyze the data and derive an equation to describe the observations.

DIY Sun Science

This iOS app for iPhone, iPad and iTouch, allows families and educators to investigate and learn about the Sun at home, at school, or anywhere. It provides 13 free, easy to use, hands-on activities, plus live images of the Sun from NASA's SDO satellite, videos of the Sun, and more.

Can an Astronaut on Mars Distinguish the Earth from its Moon?

This math example explains what celestial objects a person can see with the unaided eye from the vantage points of Earth and Mars, using simple math, algebra and astronomical distance information.

What Does Life Require?

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).

Identifying Materials by their Reflectivity

In this problem set, learners will apply the concepts of reflectivity and absorption to derive the likely composition of the materials described in different scenarios. A table with the reflectivity of common materials and the answer key are provided.
