Science 9 - Homework was corrected, the answers are posted on the main feed. Students learned about the movement of the Earth in class today. They will have a short quiz on this at the start of class tomorrow.   Biology 112 - Students had a quick follow up in regards to the impact the surface area:volume ratio has on cell size. Students were then given a timeline assignment (posted on main feed) where they will learn about spontaneous generation and how it is no longer accepted in the scientific community. This should lead students to the development of the cell theory which was discussed in yesterdays class. This assignment is due on Monday, February 7th.
