A study examined the ability of 32 grade-5 students in Alberta (Canada) to interpret Radarsat satellite radar images. The students were able to interpret most elements of the images, but working directly with the CD-ROM proved too difficult for them. The Radarsat images have limited value as a geographic resource at the grade-5 level. (TD)

Argues that Radarsat satellite images should be used in elementary classrooms to teach geography. Studies the abilities of children to interpret features of a Radarsat image. Shows that they can interpret major geographical features on the image but had problems finding Radarsat locations on road maps. (DSK)

Describes the first moon-radar echo experiment conducted by Zoltan Bay in Hungary and comments on Bay as a model for contemporary physics education. (DDR)

The discovery of radio waves, infrared, and x-rays and their importance in describing the universe and its origins is discussed. Topics include radio waves from space, the radio pioneers of World War II, radio telescopes, infrared radiation, satellites, space missions, and x-ray telescopes. (KR)

Describes the Canadian Radarsat Satellite and remote sensing in order to demonstrate that teachers can incorporate this technology into the classroom. Maintains that third, fourth, fifth, and sixth grade students can understand and interpret remote sensing images and Landsat images. Provides a list of teaching resources other than the expensive Radarsat CD-ROMs. (CMK)

Suggests how to use remote sensing techniques and data in geography courses in high school and college as well as in geography research. Tips are presented on using techniques such as topographic maps, vertical aerial photographs in stereo pairs, satellite images, and SLAR images (which are particularly useful in teaching landforms and geomorphology). (DB)

Describes the nature, history, and applications of Doppler radar detecting the speed of moving object. Gives an example of measuring the radial velocity of a scattered wave. (YP)
