Wednesday 12/09/09 - In Class and Homework

We went over the typed study guide for chapter 12 today (Period 6 began going over the book study guide as well). The homework was to take the Chapter 12 "Chapter test" on the Campbell site and to check the results. (see above). Quiz on Chapters 12 and 13 Friday.

Tuesday, December 8th - In class and Homework

We used the computers today to investigate some meiosis (and meiosis vs mitosis) animations and to take notes to reinforce some important concepts. We used our campbell site as well as 2 sites listed at the right (Chapter 13 animations). The homework is to finish this (if necessary) and to study for Friday's quiz (30 questions MC - chapters 12 and 13).

Monday, December 7th - in class and homework

We used beads and other manipulatives to symbolize mitosis and meiosis, to work through the different stages of each, and to answer questions regarding genetic stability and genetic variability. The homework is to finish the 2 handouts from last Thursday, and to have all of chapter 13 read.

Friday, December 4th 2009 - In class and homework

We continued to work on yesterday's handouts, as well as test corrections. The test corrections are due Monday, and the 2 handouts should be finished by Tuesday.

Thursday, December 3rd In Class and Homework

We received the following handouts in class - the chapter 1 objectives, the book chapter 13 study guide and some questions generated by the instructor. Furthermore, the scores for the chapter 8-10 test (multiple choice) were given back, with the specific test question number of each question missed indicated. Students can earn back 1/2 credit for each missed question by coming up with the correct answer with an explanation (or supporting fact). The answers to the chapter 12 study guide were posted on the blog (see below) so students could check their answers. The test corrections are due Monday. Students should work on this and/or reading Chapter 13 tonight.

Wednesday 12/02/09 - In Class and Homework

We began class watching the animation of the stages of mitosis from the Campbell web site (on the projector). We then used the computers to play the cell cycle "game" and view 2 other sites dealing with the cell cycle (and cancer). We came back to the front projector to review the stages of the cell cycle and to see a diagram describing control of the cell cycle (with cyclins and CDK). The homework is to review Chapter 12 and finish up the book study guide (if necessary). Also, the study guide with the stages of mitosis drawn was collected.

Tuesday, December 1st - in class and Homework

We used time in class today to continue to work on the study guides as well as use the microscopes to view the different phases of mitosis. By tomorrow, the 2 study guides should be finished, as well as the reading for chapter 12.
