This activity introduces the primary colors of light. Satellites transmit images to us as a series of numbers, and this activity is designed to show how numbers are combined to create images using the primary colors of light. Students work in groups... (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 article describes an indoor, game-type demonstration, incorporating physics (EM wave modulation), math (binary codes), space technology, and music to show how spacecraft put information into the radio signals they send back to Earth. The... (View More)

Audience: Middle school

This is an activity about digital imagery and technology. Learners will create a picture using graph paper containing ones and zeroes and instruct others to reproduce it without showing it to them, just like digital technology. After, in groups,... (View More)

Students will collect samples of particles in the air on simple slides they make themselves. They will classify, count and chart their findings, draw conclusions, make predictions, and compare their findings to other available data. Supplies needed... (View More)

In this activity serving as an introduction to remote sensing, students list what they remember seeing in a familiar environment, check their accuracy, and discuss the results. Then they apply their experiences and new skills to an unfamiliar... (View More)

This is an activity about observation. Learners will make a 3-dimensional model of a mock planetary surface inside a box, and then place a lid on top. They will then introduce a simple probe, such as a pencil or stick, at various points through... (View More)

Students will first try to imagine what their school and neighborhood look like from “A Bird’s Eye View” and draw a detailed picture. They will follow this with a study of an aerial photo of their town. Materials required for this activity... (View More)
