This is a lesson about detecting ice on the permanently shadowed craters of Mercury and the Moon. Learners will consider what might be in that ice and will examine why the polar regions of Earth, Mercury and the Moon are colder than elsewhere on the... (View More)

This activity explores how ancient Sun observers made use of natural and built structures to mark solar alignments observed at different times of the year, particularly around the solstices and equinoxes. In Part 1, the teacher prepares a horizon... (View More)

This interactive, online activity asks learners to read information and tables to determine the correct sequence of events associated with servicing the Hubble Space Telescope. Students use the clues provided in the text and graphics to organize the... (View More)

This is a activity about applying the scientific method to a design challenge. Learners will design and build a platform that will be placed on a heat source. The platform is expected to serve as an insulator for a cube of gelatin. The goal is to... (View More)

This is a lesson about radiation and the use of the scientific method to solve problems of too much radiation. Learners will build snow goggles similar to those used by the Inuit (designed to block unwanted light, while increasing the viewer's... (View More)

This is a poster about the NASA Deep Space Network (DSN) - an international network of antennas that supports interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe.... (View More)

Remote sensing, using Thermal Infrared Multispectral Scanner (TIMS) data, has lead to the discovery of previously unknown roads in the canyon area of New Mexico once occupied by the Anasazi culture. Students will use those images, along with maps... (View More)

This activity is about the Mars Pathfinder spacecraft. Using cardboard and other materials, learners will create a two dimensional model of the spacecraft. A diagram with approximate measures of each component is provided. Note: Find the latest... (View More)
