Mitosis Vocab quiz....see earlier blog for list of words you can expect to see on quiz
started your cell cycle drawing projects
You did not finish these project in class, but you will be given some more classtime in the near future to work on these...
Next class we are going to talk about cancer and you will be given a group to work with and you will create a presentaion based on a reading I assign your group!
Have a great weekend guys!

Period 2+3 enjoy the long weekend!
Ch 9 TEST MAKE UPS HBIO!!!!!!!
If you were absent for the day of your ch 9 test, plan to stay after school on wed 2/18 to make it up!
I am not available after school on Monday as I have an academic council meeting and I will be out of the building at a conference all day thurday and Friday!
Remember it is part of the CCHS handbook guidelines that if you are absent on the day of a test you have one school day to make that up. Please see me if you have concerns. For anyone who can not stay this day and has to take the test the following week, your exam will be all essay.
Have a great weekend!
