What's the Frequency, Roy G. Biv?
While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...
Space Awareness
A View From Above
Analyzing and interpreting satellite data takes knowledge and patience. Through a detailed lab investigation, young scholars learn the process of analyzing this data. They use technology to create color images and maps from real...
