The Invaders of Texas program is a successful citizen science program in which volunteers survey and monitor invasive plants throughout Texas. Invasive plants are being introduced at alarming rates, and our limited knowledge about their distribution is a major cause for concern. The Invaders of Texas program trains citizen scientists to detect the…

The area of geological mapping in the United States in 1978 increased greatly over that reported in 1977; state geological maps were added for California, Idaho, Nevada, and Alaska last year. (Author/BB)

Describes geography activities for elementary students. In the first activity, students learn how to understand coordinates and use them to read maps. In the second activity, students learn the concepts of the legend as well as how to use it to find their way around on a map. (PR)

Discusses the scientific knowledge available to Christopher Columbus and how it influenced his geographically flawed, yet historically significant, decision to sail west in order to travel east. Factors discussed include Aristotle's conclusion that the earth was round, early measurements of latitude and longitude, and early map-making attempts.…

Instructions for constructing contour models from topographic maps are presented. Includes materials needed, sources of topographic maps, tips for drawing lines, and preparing the model using cardboard. Indicates that the model is a valuable instructional tool for turning topographic maps into "real" contours of land. (Author/JN)

An aerospace education activity is described which is suitable for grades 3-12. Students piece together several images from the Landsat satellite to make a mosaic of their state. From the mosaic clear acetate overlay maps can be made relating to such subjects as agriculture, geology, hydrology, or urban planning. (BB)

Describes an activity by which college students can evaluate various urban environments through a series of responses to polar adjective pairs. This activity clarifies how earth science students feel about the environment, and it also teaches them contour mapping. (HM)

Describes an exercise where a team of students constructs a scale map of objects located on their laboratory tabletop. Another group then tries to reorient the objects to fit the groups map. This leads to a discussion concerning the aspects of good and bad maps. (PR)

Discusses how concept maps with two dimensional diagrams which show hierarchical relationships among concepts of a discipline can be used in teaching physics. An example for teaching a course in electromagnetism at the Federal University of Rio Grande do Sul, Brazil is presented. (HM)

The making of topographic maps is described as a sequence of the following steps: establishment of control, photogrammetry and field operations, annotation of photographs, stereoplatting, editing, preparation of color-separation plates, and printing. Precise standards are emphasized. (Author/SA)

Map making is described in the context of extraterrestrial areas. An analogy to terrestrial map making is used to provide some background. The status of projects designed to map extraterrestrial areas are discussed including problems unique to this science. (CW)

Designed to serve as a complement to the Unesco Technical Papers in Marine Science, this report concentrates on theoretical and practical problems of geological mapping of the sea floor. An introduction is given to geological mapping procedures at continental margins as well as some practical recommendations taking as an example the African region…

An approach to mapping work in the elementary classroom is presented. Described is a sixth-grade class working with mapping activities for the first time over a three-week span. Activities described include mapping of a classroom, the importance of a key, and important map characteristics. (DS)

Presented is a teacher's guide from the Elementary Science Study offering suggested mapping activities. This guide is organized into four general sections: (1) Finding a Place; (2) Finding Your Way; (3) Looking at Scale; and (4) Outdoor Mapping. Each section suggests activities for several lessons; materials and questions are listed for each…
