Satellite Imaging, Electromagnetic Spectrum, and Echo The Bat

Echo The Bat

This book was developed with a grant from NASA to introduce elementary age students to satellite imaging. The web site had the complete book on line plus student and teachers pages with excellent information and graphics about the electromagnetic spectrum. The student and teacher resources would be appropriate for elementary and middle school students.

Remote Sensing

Excellent Student site for remote sensing. Explains the difference between photographs,

Landsat true color images, and Landsat false color images.

Electromagnetic Waves

This is a phenomenal web site that explains the different types of electromagnetic waves.
Radio waves, television waves, and microwaves are all types of electromagnetic waves.

They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next. Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.
