Weeks 5 and 6

• Tues 9/26:  Go over Cell Worksheet.  Draw and measure your cheek cells.  Work on magnification DBQ (pp 6-7).  I will check in with you about your Cell Model Project, which is due Monday 10/2.
• Thurs 9/28:  Observing and drawing Volvox, Hydra, Amoeba, and maybe more.  Do you have references for your Cell Model?  Do some work on your cell model project, due Monday 10/2.  
• Mon 10/2:  Set up Cell Model Projects and write-ups on the tables.  Walk around and assess student Cell Models.  Finish up the Microscope Lab.  Observe Paramecium, Scenedesmus, and bacteria.  Wrap up your drawings (did you calculate magnification for all, showing work?).  Answer questions on the lab hand-out.  The completed lab is due Wed 10/4.  Read 1.3 in the text if not already.
• Wed 10/4:  Turn in Microscope Lab.  Introduce plasma membrane structure.  Do Davson-Danielli DBQ on pp. 28-30.  
• Fri 10/6:  Finish and check off Davson-Danielli DBQ.   Bubble Lab.  Digestion of yeast in paramecium lab.  Read 1.4 in the text.

Cell Model Project

Cell Model Project

What:

Build something:  In a group of 2-3 students, you will build a 3-D model for a eukaryote cell (pick animal or plant).  Using common household materials, you will represent at least 7 (10 for groups of 3) of the organelles.  You must include the nucleus, mitochondrion, chloroplast (for plants), endoplasmic reticulum, and ribosomes.  The others are up to you.  Choose materials that you feel make a good analogy for the functions and/or characteristics of that organelle.  

Write something:  Number the organelles of your cell and then write an explanation for each part.  The explanations should include:  1)  why you chose that material  2)  how the material suits the characteristics and/or function of the organelle  3)  how the material falls short in representing the organelle.  Be as specific as possible.

When:  

Due on _Monday, October 2, 2017_____

Grading Criteria:

Model evaluated on:

1)  Creativity (5 pts) 2)  Presentation (5 pts)

3)  Accuracy (5 pts)   4)  Enough Organelles and labeled (5 pts)

5)  Writing:  completeness (5 pts) 6)  Writing:  specificity (5 pts)

7)  Writing:  spelling, grammar, clarity (5 pts)

8)  Citation of resources (at least 2 beyond the class materials) (5 pts)

Total = 40 pts

Turnitin.com information for SPARK Lectures

In this class, we use turnitin.com for submitting many of our assignments, including SPARK lectures.  For SPARK lectures, please write a reasonably detailed summary of what the speaker said and then give your personal response to the talk.  Good summaries and responses are typically about 1.5 pages double-spaced.  We always submit them to turnitin.com.  There is only 1 submission per quarter.  Turnitin.com information for this class is as follows:

4th Week of School (Already?)

• Mon 9/18:  Take Statistics Quiz.  Then work on the Cell Worksheet while everyone finishes the quiz.  When finished, we will review parts of the worksheet, as well as talk about microscopes.  Please finish the worksheet, and read pp 3-7 on microscopes for homework.  
• Wed 9/20:  Turn in the Cell Worksheet.  Using a light microscope.  Do the Date-Based Questions on pp 6-7.  Today we will look at cork, pond water, elodea, and onion cell.  Draw clear and well-labeled diagrams of each.  Read 1.2 for homework.
• Fri 9/22:  How to calculate magnification.  Do DBQ on pp. 6-7 in your notebook.  Continue with the microscope lab, making clear diagrams, and calculating magnification for every drawing.  Introduce Cell Model Project and go over the Cell Worksheet.

What's on that Quiz on Monday, 9/18?

Be Able to:

• Count sig. figs. and compute and round appropriately
• List the requirements for a good IB graph and give a sketch of what one might look like
• Use TI-84 to calculate standard deviation, t-test, mean, and n (number of stats)
• Figure out degrees of freedom, find critical value (using chart), and interpret meaning
• State meaning of standard deviation and ranges for 1 and 2 standard deviations (68% and 95%)
• Calculate uncertainty (high-low)/2
• Propagate uncertainty for adding/subtracting and multiplying/dividing
• Calculate number of organisms in a grid using values from several quadrats

Third Week of School

• Tues 9/12/17:  Go over how to show work using the standard deviation and t-test formula.  Calculate the standard deviation and t-test for the class brine shrimp data and determine whether the salinity (3 or 5% salt water) had a significant impact on the hatching rate.  Show work for this on the back of the statistics packet.  As a class we will learn how to do a histogram and then each student will make one using the vole data from the statistics packet.  The rest of the time will be for working on the statistics packet.  When you are done, turn it in.  Get the TI-84 and Brine Shrimp lab hand-out checked off.  Statistics Packet should be turned in before the end of class or at the beginning of class on Thursday 9/14.
• Thurs 9/14/17:  Review statistics material.  We will take a quiz on it on Mon 9/18.  Begin Cells Unit by starting Introduction to Cells Worksheet.  Homework:  prepare for the quiz and start reading 1.1 in the text.
