Welcome back to the blog after a brief rest around the Midterm exam!                       
Homework tonight:                    
 7th Graders: work on your infectious disease project. Tomorrow I would like to see some progress. Also, check out the article about how scientists got yeast cells to clump together, with some discussion of why that was an advantage: http://www.nytimes.com/2012/01/17/science/yeast-reveals-how-fast-a-cell-can-form-a-body.html            
 Sixth (6th)Graders: Write a brief Reflection to respond to this question: What do you  know about the Water Cycle?  A Reflection is written on the left sided page; put another way, it's written on the back of today's (or in this case, yesterday's) page. In a  Reflection, you think back about what you know or what you found out.  In other situations, I would ask you to tell me how you would do things differently, or what you could do better next time, but that doesn't fit this context. "Brief" means at least 3 sentences, here.
