Yesterday in Anatomy, we took a quiz on cell membrane transport - the ways things get into and out of a cell, and also tonicity of extracellular fluids and how they affect the cell.  We lectured on mitochondria, smooth and rough endoplasmic reticulum, the Golgi apparatus, and the elements of the cytoskeleton.  We also prepared our journals for today's and tomorrow's labs, which are in your folders.  We did Introduction to the ATC 2000 today and we will do Using the ATC 2000 tomorrow.  You will have to make these labs up after school when you get back.  We are testing on these labs on Friday, and it is a major test grade.  Thursday we will be looking at and drawing animal cell slides that show various stages of mitosis. Be sure to review that section in your book in Chapter 3 if you will be here then.

 

Yesterday in Chemistry, we went over the homework from Friday and took questions.  We then talked about the characteristics of direct and inverse proportional relationships (what graphs and math formulas look like).  Then we prepped our lab journals for a lab called Density of a Liquid.  You will not have to make up this lab, but you will have to get data from me, and write it up in your journal as if you had done it.   Tomorrow we will go over the graphs we made from the lab today, and use the slope to determine the density of our liquids.  We will also do some additional practice problems from Chapter 2 to be sure we are confident in all the things we have learned to do.  Our test on Chapter 2 will be on Thursday, and I will also be taking up completed lab books then.  Unless you have missed a lab that has to be made up, you must turn in your journal at that time.
