Singing

Today we are going to sing.  I only sing once a year because, unfortunately, bugs always crawl out of the wall and die when they hear my singing voice.  BUT I'm gonna sing today and so are my students.  Here is the song lyrics we are going to sing.  There is also a picture we are going to evaluate for abiotic and biotic aspects.  Finally we are going to analyze various ecosystem relationships using this article from MotherEarthNews.com about Keystone Species in Yellowstone and this review sheet.

Today's start-up is "What is the difference between abiotic and biotic?"
