Update for October lessons, Potions Lab

If you have not already done the ecosystem quiz on 2.1 , make sure that you do the 2.1 quiz. If you've already done it, please don't do it again.    It is still up due to my absence (bronchitis is persisting). If you have any questions with regards to nutrient cycles, please email me.  I'm expecting to go back to school soon.

Next week's lessons: 
Oct 28:  Review session on nutrient cycles and nutrient cycle quiz will be up.  And a general Q and A on our lessons so far.
Oct 30:  there will be a lab on Dry Ice to explore the physical properties of Carbon Dioxide.  It'll be our Halloween lab.  You will write this lab up and hand it in.  It'll be a classic potions lab, for all you Harry Potter fans out there.

Solid Carbon Dioxide: -73 degrees celsius!

observe the properties of carbon dioxide and discover how to make carbonic acid in the ocean
