Biology 11/30/11 HW

Three handout were given out.  Read and highlight the important sections and then color the images so that each structure named and pictured has a different color.  If you can use the color for structures that appear on the different images i.e. light green for nuclear membrane on all pictures,  that can give you a little e.c.

Biology Cell Analogy update

Youy may work with students from other classes but each person must present during their own period, if you choose to.  Updated due date is Friday 12/9/2011.

Earth science 11/23/2011

Do the "problem-solving lab " on pg 63 of Earth science text.  use the following critical thinking questions instead of the ones in the book .  All answer should be in complete sentences , where it applies!  Happy thanksgiving!!!

Critical Thinking

1. These atoms form ions and create an ionic bond. 
1. How many electrons would orbit A? B? 

b.  What would be the net electrical charge of ion A & ion B?

3. Why would ions of opposite charges bond?

4. What would the chemical formula be for AB?

2. How might you draw a model of Mg & Cl

Biology- Cell Analogy 2011

Task: 

You are to look at the internal structure and function of a cell and create an illustrated diagram, t-chart, web page, power point, story or other teacher approved project format that compares the cell and its’ organelles to an analogous system such as a school, a car, a factory or whatever; each of which have important smaller parts with important functions.

Your project needs to include each organelle listed below and its role in the cell and it will need an analogous system to the cell and each organelle.  Make sure you compare and explain the roles of each organelle and their analogous counterparts.

Ex: Cell = School, where the nucleus, which controls all cell functions, could be compared to the principal in the school.  If you use this example I will not give you higher than a 3 on #3 of the rubric.

Use the text book, Internet, notes and your brains

Grading (subjective rubric = score of 5-0 points based on my feelings about the quality and evident effort on the project and its’ parts)

Grade categories

1. Cell organelles/structures and function
1. Include:  cell membrane, cytoskeleton, nucleus, ribosome, endoplasmic reticulum, golgi apparatus, lysosomes, vacuole and mitochondria.  Bonus points: for doing a plant cell (cell wall and chloroplast) = 30pts; Include flagella or cilia = 15pts

       !!!No analogous structures = no Bonus Points!!!

2. Analogous system with corresponding features for each organelle/structure and function
3. Quality (color, creativity, attention to detail…)

Deadline Due Date:  Even period on Friday 12/02/2011

Biology 11/22/11

Read and take notes for Ch 7.2, cell membranes, on pgs. 187-191.
