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.

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?

    1. Why would ions of opposite charges bond?

    1. What would the chemical formula be for AB?
  1. How might you draw a model of Mg & Cl

Biology- Cell Analogy 2011

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

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

ALL Classes:

Measurement / Metric Quest next class-  STUDY YOUR NOTES!!!

Dimensional Analysis problems worksheet - show all units and work

3rd period only!:  Finish Final write up of mass Lab for Tuesday 11/15/2011

the FD will be on a separate sheet(s) of paper from your rough draft , one for each student.

Title:  Just how much Rubber is in a Rubber Stopper?
Question:  How will the rubber stopper’s actual metric mass compare (more, less or same mass) to the converted mass taken from posted English standard measurements?

Hypothesis:  The Rubber stopper’s actual mass will be________________ then/as the posted mass.

Test:  By using a metric balance to determine the actual mass of a Rubber stopper, we can convert ounces to grams for the posted mass and compare to the actual mass found using a scale.

Materials:  metric balance (triple beam pan balance), rubber stoppers of varying size, (calculator)

Procedures:  Make a diagram!!
  1. Convert the posted mass from oz → g using the following formula 1oz. = 28.3 g 
  2. Take the mass measurement of the rubber stopper on the metric balance.
  3. Do this for four different rubber stoppers with different posted masses (each table member should do all parts of the experiment for at least one sinker)
  4. Subtract the measured mass in grams from the posted mass in grams to determine the relative error.  You may disregard any negative numbers9 take an absolute value of your result).
  5. Take the relative error in grams and divide by the converted posted mass, in grams, and multiply by 100 to determine the percent error.

Rubber stopper #
Posted mass
Converted (g)
Measured mass
Relative Error
% error


Analysis:  include your calculations and math work for doing the oz-g conversions, relative and percent error. 
Make a Bar graph of actual versus converted mass values of the rubber stoppers used.

Conclusion: (restate the hypothesis, explain how you answered the question or not and compare numeric results to prove or refute your hypothesis, discuss observations as possible errors and propose a next step and who outside of this science class might care about your results)
