Cow’s Eye Dissection

  1.  Activity:  Cow’s eye dissection.  See copy of handout here:  Cow Eye dissection from the Exploratorium.  Complete the questions.  Draw a picture of the interior and exterior of the eye and label the parts you can see.
  2. Progress report and Work habits self-evaluation and goal setting sent home.  If you are missing assignments, tests, or have an “I” standing and need to complete it, work on it during Spring Break and see me when we return back to school.

Chapter 1 Test

  1. Today, students wrote the chapter 1 test (Cells and the Microscope).
  2. Check last day’s blog for the list of assignments you should have completed and handed in for chapter 1.  If you still need to complete them, try to finish them by the end of this week.
  3. Do:  read over the Cow’s Eye Dissection handout.  See copy here:  Cow Eye dissection from the Exploratorium.  We will be doing the lab next class.  You can answer some of the questions before you do the lab!  See this website for a “virtual” lab, video, and extra info:

You can bring your own gloves if you’d like.

If you cannot be in the room when we do the lab, please talk to me before your lab day so I can prepare and alternative assignment for you.  It will be from your textbook:  p.235 Natural Vision Systems – you will be doing “Report Out” #1a where you will make a Venn diagram comparing the vision systems of a creature of your choosing to that of a human.  For ideas of what kinds of creatures to choose, see here:

  5. Do:  Cell Coloring sheets to help you identify the parts and function of the cell.  Make Column notes from the information you read.  Animal and Plant Cell Coloring pages
  6. Do:  Start section 1.2 worksheets (not due yet) – see previous day’s blog for the worksheets.
  7. Students received a term progress report of what they have covered so far.  The ch6 test is still being marked (hence the blank).  If you have an “I” (incomplete) or a blank space, you need to complete these asap.  Tues. Feb. 25 is a Goal Morning.  Come in to complete them
