In this activity, students use multiwavelength images of stars in different stages of evolution to investigate how the initial masses of the protostars determines their evolutionary paths. Images include stellar nurseries, protostars, supernova... (View More)

This guide is for free IDL compatible software that integrates with NASA's Lunar Reconnaissance Orbiter (LRO) data, allowing the user to manipulate data images from the LOLA tool aboard LRO.

Students are introduced to radar imaging. The 15-page guide begins with a review of the electromagnetic spectrum then provides background information on the Lunar Reconnaissance Orbiter (LRO) and the Mini-RF radar-imaging device aboard the LRO. Two... (View More)

Learners will shape mashed potatoes into their own odd-shaped asteroids. They can then bake them in the oven to turn them (more or less) asteroid color, and eat them for dinner.

Balloons are used to construct a scale model of the Earth, Earth's Moon and Mars in relation to each other. Students use this model to predict distances and reflect on how scientists use models to construct explanations through the scientific... (View More)

Colored beads and string are used to create a model of the solar system in order to explore size and distance relationships among planets. A second model for comparing planetary sizes uses common types of fruits and seeds(either actual fruits or the... (View More)

After creating a model of multiple volcanic lava flows, students analyze the layers, sequence the flows, and interpret the stratigraphy. Students use that same volcanic layering model to investigate relative dating and geologic mapping principles-... (View More)

This chapter describes how to set a scale and measure distances and areas on satellite images. Using ImageJ, a freely available image analysis program that runs on most operating systems, users set the spatial calibration of an image, then select... (View More)

This chapter describes the technique of preparing GIS-ready data and shows how to map that data and conduct basic analyses using a geographic information system (GIS). First, the user will download and format near real-time and historical earthquake... (View More)

This chapter walks users through a technique for documenting change in before-and-after sets of satellite images. The technique can be used for any set of time-series images that are spatially registered to show the exact same area at the same... (View More)
