This is an activity about albedo, which is a measurement of the reflectance of a planetary surface. Learners will classify areas on an image in terms of albedo values and then sketch their own portion of an image from space. These sketches are... (View More) assembled to view the larger image that the class or group has created. (View Less)
In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions. CRaTER's purpose is to identify safe landing sites for future human missions... (View More) to the moon; discover potential resources on the Moon; and characterize the radiation environment of the Moon. The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation." (View Less)
In this lesson about cosmic rays, students will describe why cosmic rays are dangerous to astronauts. Includes information about student preconceptions. This is activity 3 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."
This is a lesson about using radar to search for water on the Moon. Learners will use images to search for water on the moon. Additionally they will learn how Mini-RF can identify surface features that are permanently shadowed, or lack any visible... (View More) evidence of surface morphology. (View Less)
In this lesson, students will learn how cosmic rays were discovered and what they are - including their size and speed. Includes background information for the teacher, questions, activities and information about student preconceptions. This is... (View More) lesson 1 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)." (View Less)
This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.
This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More) life on Mars. An extension activity investigates the connection between liquid water, biomes and plant productivity on Earth. This is the 1st of 5 activities in Buried Water Ice on Mars. (View Less)
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) ability to see in a bright region) to understand some of the engineering challenges encountered while protecting the solar cells on the Mercury MESSENGER. This is Lesson 2 of 4 at the middle level in the module, Staying Cool. (View Less)
This is a activity about how reaction wheels affect spacecraft orientation (attitude). Learners will observe Newton's Third Law (action-reaction) in the changes caused by a reaction wheel acting upon a spacecraft suspended from a support wire and in... (View More) the ensuing interfering forces from the wire support. The experiment includes an option for demonstration and for learner investigation. Notes about gyroscopes are included. (View Less)
This is an activity about light. Learners will calculate the peak emission wavelengths corresponding to objects at various temperatures, helping them understand, among other things, why the Sun appears yellow. This activity is part of "Ways of... (View More) Seeing," an interactive, educational CD-ROM from NASA's Cassini Program. The Cassini spacecraft is the first to explore the Saturn system of rings and moons from orbit. (View Less)
