Nick C. and Carson M.'s Mitosis Mobile


The front of the mobile is shown above. The back of the mobile has typed descriptions of each of the phases of the cell cycle. Unfortuntely the quality of the picture isn't great (the dept. camera is only 2.1 megapixels).

Working on Mitosis & Cell Cycle Project

Today students were given time in class to work on their cell cycle and mitosis projects. So far things are looking very promising. Here are some samples of what students are doing:

*Mitosis Mobile
*Flash Movie
*Animation
*Flip Book
*Posters
*PowerPoints
*Movie (starring students as parts of the cells)
*3D Posters
E Block will present their projects on Friday (yes, that's tomorrow).
A & B Blocks will present their projects on Saturday.
Tune in tomorrow for samples of outstanding student work.

Cell Cycle and Mitosis Project

Students will be working on their projects in class today. Below are the project guidelines.

Project Check List & Rubric

This project is worth 50 points. You will be creating a visual that represents the cell cycle and mitosis. This visual can be anything from a flip book to a PowerPoint to a poster or collage or 3D model. Make sure that your presentation includes all the following information.

A. INTERPHASE - THE TIME OF THE CELL CYCLE BETWEEN CELL DIVISIONS. (G1, S, G2) DRAW/MAKE A MODEL AND LABEL ONLY ONE PICTURE BUT DEFINE ALL THE PHASES. (You don’t need to have separate pictures for G1, S and G2). 10 points.

B. MITOSIS (M PHASE) - A FOUR STAGE PROCESS WHICH THE NUCLEUS OF THE CELL DIVIDES INTO TWO NEW NUCLEI WITH IDENTICAL GENETIC MATERIAL. DRAW AND LABEL ALL FOUR STAGES, DEFINE MITOSIS AND DESCRIBE EACH PHASE. 25 points.

C. CYTOKINESIS - THE CYTOPLASM AND ORGANELLES OF THE PARENT CELL DIVIDES IN TWO NEW CELLS CALLED DAUGHTER CELLS. DRAW AND LABEL ONE PICTURE AND DEFINE AND DESCRIBE CYTOKINESIS. BE CAREFUL! Plant and animal cells undergo cytokinesis differently. 5 points.

Creativity = 5 points No spelling or grammar errors = 5 points

Cancer: Case Study & Myths

Admit Slip: Notebook Quiz on the cell cycle and mitosis (b block: no quiz)

Objective 1: Students discuss, in small groups & as a class, the case study featured below using guiding questions. Objective 2: Students will take a true/false quiz on cancer myths and then discuss their responses.

Homework: Bring materials to class tomorrow to work on the cell cycle & mitosis project.

case study1
Sam (73) had a growth inside of his mouth for some time that he finally had checked out by his doctor. Following some tests, Dr. MacAvee, an oncologist, told Sam he had cancer of the gum (a squamous [skin] cell cancer). Unfortunately, the cancer had spread to Sam's lymph nodes in his neck and into his tongue and jaw. Dr. MacAvee told Sam they could do radical surgery to take out part of his tongue, the right side of his jawbone, and all of the lymph nodes in his neck, followed by chemotherapy and radiation treatment. Sam has refused. Sam's wife, Lois, seems reluctantly supportive of his decision. Sam's daughter, Michelle, has been lobbying Dr. MacAvee to convince her father to accept as aggressive a treatment as possible, so that Sam might have as much time as possible with his twin grand-daughters.
Questions:
1. What are the consequences of the course of treatment the doctor has suggested?
2. What is the likely prognosis (what will happen) for a metastatic skin cancer?
3. Does Sam's decision to decline treatment make reasonable sense? Please discuss from the perspective of all people involved.
4. How should a physician respond to the wishes of a family member?
1This case study discussion was adapted from Paul Greenwood's BI493 course at Colby College.

Mito-what? Looking at cells reproduce using mitosis

E Long and B Blocks
Admit Slip: How do cells reproduce?

Objective: Students will use actual animal cells undergoing mitosis to see how a eukaryotic cell reproduces.

Students will examine animal cells undergoing mitosis. These will strictly be primary observations. They will not be given any information on the stages or the order that they occur in, except the names of the stages which will be on the microscopes. Students will need to draw what they see and write the name of the stage on the handout.

Click here for images of the slides you looked at today. This should help you with the homework.

A Block:
Lecture on Mitosis and how cells reproduce.

HW E Long: Read sections 8.1 and 8.3. Read and complete the mitosis coloring sheet.

HW A Block: Read and complete the mitosis coloring sheet.

HW B Block: Read sections 8.1 and 8.3 in the text book. Cut up drawings of stages and put them in the correct order on a sheet of paper. Label the nuclear envelope, chromatin, chromosomes, centromeres and centrioles (where appropriate the in the diagrams).

Winter Break!

Have a wonderful winter break everyone! Good luck to everyone who has tournaments and races. When we get back from break we'll start with the cell cycle and mitosis/meiosis. How do cells reproduce? What happens if cells reproduce uncontrollably? Why are there two different types of reproduction?

It's JUA time!


JUA starts this Sunday at Noon in the Master Classroom. We're leaving at 4:45am on Monday so make sure you set an alarm. We'll return on Tuesday evening (you might be a bit late for study hall). Most classes only meet once next week, so you'll be finishing presenting the Anatomy Jig Saw.

Anatomy Jig-Saw (Friday and Saturday)

Admit Slip: Name as many body systems as you can

Objective: students will complete a jig-saw activity to learn the body systems and present what they learn to the class. Each person/group must state:

*Name of the System
*Major Organs/Components
*How it functions

Students will review systems by playing 2 truths and a lie.

2. Find the original research article in the EBSCO health resources database.


QUESTIONS TO ANSWER ABOUT THE ARTICLES


1. For the Magazine article: (15 points)
Give the title, author, and date of publication. (1pt. each)
Give a sentence or two that summarizes the scientific findings reported. (3 pts.)
Describe any figures or tables that accompany the article. (1 pt. if applicable)
Does the article include responses from the scientific community? Explain. (3 pts. if applicable).
Does this article give you enough information to evaluate whether or not the results are likely to be replicable? Explain. (5 pts.)

2. For the peer-reviewed article: (20 points)
Give the citation in the sample scientific format provided in the handout: authors’ surnames and initials, date, title, journal, volume, pages. (4 pts.)
Devote a sentence to each figure and table, explaining the results that are presented. (8 pts.)
How many references are cited by the article? (2 pts.)
Would you recommend this article to a friend who is a non-biologist? Explain. (6pts.)

December 14th only: How will you judge the scientific validity of information you encounter on the web or in secondary sources? (5 points)

February 12th only: Choose what you think is the most significant figure in the peer reviewed article. Write at least 4 sentences explaining the figure and why you think it is the most significant in the article.


Due dates: December 14th, January 15th and February 12th. Your assignments must be typed and include a copy of the NYT article and the actual article.

Value of the assignments:
December: Since this is your first one, it will count as a homework
