Molecular Visualization: Do this and answer questions in your notebook

Go to the Molecular Visualization Link on my Website (look under links not documents).  The purpose of this activity is for you to become familiar with the structural and 3-D conformation of organic molecules.  You should also pick up some interesting information by reading the text for each molecule. Pay special attention to the differences between the 4 polysaccharides (glycogen, amylose, amylopectin, and cellulose) because that is a specific syllabus requirement.

1. Click on glucose and observe it (it is under carbohydrates).  Use the cursor to rotate it.  Read the text on glucose.  Write at least 2 new observations down about glucose.
2. Now do the same with the following carbohydrates:  fructose, glycogen, amylose, amylopectin, and glycogen
3. Now go to the lipid category and do the same with glycerol, saturated and unsaturated fatty acids, one of the fatty acids (name it), and finally, trigycerides.

The Weeks of 10/28/2019-11/8/2019 and End of the Quarter!

The End of Quarter 1 is this week.  My deadline for late work and extra credit is Tuesday, 10/29!  Grades will be finalized on Thursday 10/31 by me.

• Tues 10/29:  Notes on Carbohydrates and start notes on lipids.  Using model kits, make glucose and then link it with the glucose of another group, showing condensation synthesis.  Also, make a fatty acid with the model kits and possibly glycerol and then link 1 glycerol and 3 fatty acids from different groups, showing the formation of a triglyceride.  Read 2.3 if not already.
• Thurs 10/31:  More notes on lipids.  Saturated vs unsaturated fats and their properties.  How to calculate BMI.  Do DBQ's on p. 81 and pp 85-86 in your notebook.  Use molecular visualization software (link on website) to observe different polysaccharides.   Answer questions in your notebook.  Read 2.4.
• Tues 11/5:   Protein worksheet done in class.  
• Thurs 11/7:  More on proteins.  Make clay models of a monosaccharide, and amino acid, and a fatty acid or glycerol.  Start nucleic acids.  Read 2.6.

Potato Osmosis Lab

You took data with a group, but I would like to write this up individually.  That means that each of you should design your own data table, organize your own graph, etc.   

Your Lab Should Include:

1. A focused question
2. A neat organized data table for your raw data and your processed data results. You should include measurement uncertainty, but don't need to propagate uncertainty for averages (because it wouldn't really make sense in this case).  Include 2-3 observations of the potatoes.
3.  Sample calculation:  Show a sample calculation for percent change.  Make sure that you include a blank equation, the equation with numbers inserted, and the correct rounded answer with units.
4. A graph!  This can be hand done or with a computer.  See the DBQ on p. 42 for help, but of course your graph should have an appropriate title, labels, units, annotation, etc.  You do not need to put on error bars this time because you will not be propagating error for the percent change calculation.
5. Conclusion/Interpretation of results:  Refer back to your question.  Use specific data to back yourself up.  Try to EXPLAIN your results using osmosis concepts.  Finally, were you able to determine the salinity of the potato?  Explain why or why not.
6. Evaluation:  Evaluate your results by discussing at least 3 sources of uncertainty, their impact on the results, and your suggested improvements (this can be done in a table as we did before)

I would like your lab to be turned in through turnitin.com, but if you have calculations and/or a graph that you want to do by hand, just make a note of that in your lab and then turn the hard copies of calculations/graph in my box with your name on it.

The Week of 10/7/19

• Mon 10/7:  Review vacuole formation in paramecia.  Take notes on vesicle movement in secretory cells and notes on the 4 types of movement across membranes.  Start Potato Osmosis lab.  Groups will mix different salinities of solution, then cut up pieces of potato, record their masses and leave them in the solutions until Wednesday.  Check off Paramecium Lab hand-out with completed 1.4 questions on the back.
• Wed 10/9:  Finish checking off Paramecium/1.4 worksheet.  Remass your potatoes and calculate the results.  Each individual will do a lab write-up and submit through turnitin.com.  Due Mon 10/14 (there will be some additional time in class on this day to finish it)
• Mon 10/14:  Go over worksheets and data-based questions for the cells unit.  Review cell concepts, including looking at prepared slides and practicing drawing them.  Work time for the potato osmosis lab, which is due by the end of the day.
• Thurs 10/17:  Kahoot review for the Cells and Membranes Test.  Start Biochemistry.
• Mon 10/21:  Cells and Membranes Test!  When finished with the test, do the 2.1 questions in your notebook!
• Wed 10/23:  Notes on biochemistry and the amazing properties of water.  Read 2.2.
• Fri 10/25:  Water Olympics Lab.  More notes on the amazing properties of water.
