Lunar Sample Disk
This program consists of six samples of lunar material (three soils and three rocks) encapsulated in a six-inch diameter clear lucite disk. The disk is accompanied by written and graphic descriptions of each sample in the disk and a cd with a powerpoint presentation of exploring the moon. Also included in your package will be a teacher's guide that has class room instruction and other printed materials.
Lunar sample disks include the following types of material.
- Basalt: Solidified lava found in the dark lowland mare or "seas".
- Breccia: Rocks made of fragments of other rocks that were broken and welded during collisions between the Moon and meteorites.
- Highland Soil: Fragments composing this soil are from the breakup of highlands rocks by meteorites.
- Anorthosite: White rock consisting of feldspar crystals. Predominate rock of the lunar highlands.
- Mare Soil: Most of these grains were produced by meteorites hitting lunar basalt.
- Orange Soil: Volcanic ash from a lunar eruption 3.5 billion years ago. Recovered by Apollo 17 astronauts.
Lunar samples are accompanied by a copy of the "Exploring the Moon" educator's guide, and a videotape of"The Moon: The Geologic History and Future Exploration". As part of the NASA Educator Resources, the Educator's Guide may be downloaded at no charge.
