Our in house astronomer, Mr. Pickett, was kind enough to share a presentation with our second grade class on Astronomical Spectroscopy.  In case you are unfamiliar with the topic, which I feel many of us are (haha), here is the definition:  Astronomical spectroscopy is chiefly concerned with the analysis of objects in space. From simple spectroscopic analysis of an astronomical object, we can measure the spectrum of electromagnetic radiation and determine its wavelength. This can tell us about the object’s chemical composition (as a factor of their spectra and mass), temperature, distance and speed (using a function of their wavelength and the speed of light).

Is it more clear now?  Just in case, here is additional information to increase understanding.

Second graders embraced the topic!  They made connections with their learning, asked intelligent, thought provoking questions and showed great enthusiasm for the topic.  Take a look:
