This is a lesson about spacecraft design. Learners will think like engineers as they are presented with problems that the NASA team faced when designing a spacecraft to travel to Saturn. Students work with partners to think of solutions to address... (View More)

In this activity, students consider the sudden release of a tremendous amount of kinetic energy when an extraterrestrial object strikes the Earth. In small groups, they study satellite images that show possible evidence of impact events. To... (View More)

This activity helps students understand the connections between remote-sensing technology, computer imagery and land cover assessment, and models how a satellite sensor communicates information to a computer. Digital information from a map created... (View More)

In this activity, learners work in teams to construct specific components of a model of the High Energy Solar Spectroscopic Imager (HESSI) spacecraft. Afterwards, the teams make presentations on the results of their effort. Note: HESSI is now named... (View More)

In this activity, learners will build a structure using a shoebox, aluminum foil, paper, rubber bands, glue, tape, and other common materials that will meet the following criteria when tested: 1) protect an ice cube from melting under a hot lamp or... (View More)

In this activity, students simulate how light collected from a space object converts into binary data and reconverts into an image of the object. A pencil and paper activity demonstrates how astronomical spacecraft and computers create images of... (View More)

This is a lesson about light in the outer solar system. Learners will demonstrate the effect of the inverse square law of illumination with distance and connect this to the functioning of solar panels at Saturn. Requires a silicon solar cell... (View More)

In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds... (View More)

Students examine a series of remotely-sensed images of the US, scaling from the continent to San Francisco, and distinguish the concepts of scale and resolution. At greater resolution, students are able to identify different land classes on the map,... (View More)

Students will "digitize" photographs of human faces using various grid sizes and shades of gray. Through this activity, they gain an understanding of image resolution and how much information is needed to answer various questions.This introductory... (View More)
