Nitrogen Cycle

REMINDER: You have a good sized quiz on Monday. Anything in the first two packets is fair game as well as the nitrogen cycle.

For those of you who may have missed it: A massive volcano eruption caused the largest shut down of airports in peacetime.

After talking about the volcano, students had a reading quiz. We learned about the nitrogen cycle and in some classes read an article about nitrogen-fixing cyanobacteria.
