Science 9:  Today learned about the Carbon stored in soil.  We watched this clip about decomposing pumpkin to observe the bioturbation that occurred and to help us consider the components of soil (water, detritius, rock fragments, bacteria, fungi, and invertebrates.  We also watched this clip to help us visualize the decrease in volume of biomass, to help us reason that CO2 is leaving a compost pile.  We made a bar graph using this data to show Carbon Storage vs Biome.  

Chemistry 12:  Today we wrote our Acids and Bases Unit Test.  Well done!  No homework in Chemistry 12 this weekend.
