This math problem determines the areas of simple and complex planar figures using measurement of mass and proportional constructs. Materials are inexpensive or easily found (poster board, scissors, ruler, sharp pencil, right angle), but also... (View More) requires use of an analytical balance (suggestions are provided for working with less precise weighing tools). This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Students confront the challenge of improving global agricultural production in order to feed increasingly larger populations. Students evaluate tables, maps, graphs, photos and satellite images detailing global population growth patterns and... (View More) agricultural production levels in order to formulate recommendations. The role of technology is examined throughout. This investigation includes two activities: 1. Students form six teams representing major world regions to consider the need for increasing agricultural production; 2. Students conduct a case study of Mozambique and conclude by distributing and defending monetary investments for possible agricultural production increases. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 3 of three found in the Grades 9-12 Module 2 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 2, while related, can be done independently. (View Less)

Water supply in the Southwestern United States depends on snow. Students discover its importance through analysis and evaluation of data, satellite images, space shuttle photos, and ground-based observations, and then apply their findings in a... (View More) role-play. Working in seven groups representing the states in the Colorado River watershed, students assume the roles of U.S. senators to propose and defend their stand on the allocation of Colorado River water by state and by usage.
