Happy Winter Break!!

Hello Students!  I hope that you are all staying warm and safe until it finally thaws out!  Maybe some of you even made it out of town.  The Cell Respiration and Photosynthesis Test will be moved to Friday, January 6, 2017.  When we come back to school on Wednesday, Jan 4, there will be some time to review, but we will also move on to Cell Division.  I recommend that you review the test topics a few times a week to keep it fresh.  Remember too that Winter Break can be a great time to read an Extra Credit biology book.  Due to the snow days, (the first semester has been extended a week).  What maybe not!  Stay tuned!

If you have any questions or concerns, don't hesitate to contact me.  Enjoy your extended Winter Break!

Snow Day Update!!!

Hello Students!  I hope you are enjoying your snow day!!  The Metabolic Rate Lab assignment is in turnitin.com and should be turned in some time today.  Feel free to e-mail me questions, as some of you already have.  Also, I have uploaded the Cell Respiration and Photosynthesis Review onto the documents section.  We will take notes on the Calvin Cycle, Calvin's experiment and structure and function of mitochondria and chloroplasts on Monday.  Wednesday we will review the processes and play Kahoot.  Friday 12/16 will be the test.  Please read and review these topics so that you can get any of your questions answered on Monday and Wednesday.  It is a lot of material and requires multiple viewings to make sense, but it will eventually come together if you keep at it.

Also, I have dropped the Chromatography Lab for now.  It is required on the syllabus, but we don't have time for it now and will do it after Winter Break.

Stay warm and safe out there!
Ms. Kenny

Metabolic Rate Lab: due Thursday 12/8 through turnitin.com (can be turned in all day, doesn't have to be in class)

What do you need on this??

1. Question
2. Background (can include your initial observations when we did practice trials, background on why you chose the question, etc)
3. Data Table:  neat, labeled, titled, with units.  Only include the data you used (minimum of 20 individuals).  Using a random method for choosing your data is preferred where there are more than 10 available.
4. Calculations:  For each individual, calculate 2 means, 2 uncertainties, and % change.  For groups use the percentage change value and calculate 1 mean for each group, 1 standard deviation for each group, and a t-test BETWEEN the 2 groups.  Do a sample calculation for each type that you did.  You can use the statistics/critical value list I put on my website to help.  Look up critical value and compare t-value to critical value and interpret meaning.
5. Conclusion:  refer back to question, state conclusion using data (numbers) to back yourself up.  Refer to the means and t-test results and include meaning of the t-test.  Try to explain what your results mean in terms of science.
6. Evaluation:  Describe at least 3 sources of uncertainty or limitations in this lab, being specific.  Describe how each impacts the results, and suggest realistic improvements to the procedure (not, we needed more time!!).  You can present this section in a chart.

Class Activities from Tuesday, November 8th. Do these in your notebook. We will check them off next Tuesday 11/15

Making DNA and RNA Models with Beads

1. Using the beads make a double-helix with 10 complementary base pairs
2. Unzip the double helix.  Using one strand as a template, make an RNA strand (remember to use pink beads for ribose sugar)

Questions done in your notebook:

1. How are the bead models a good representation of the nucleic acids?
2. How do the bead models fall short?
3. Give 3 similarities and differences between DNA and RNA

Molecular Modeling Using Software (see my website for link)

1. Go to the Carbohydrates and look at:  glucose, galactose, sucrose, lactose.  Describe what you see for each.
2. Now look at glycogen, amylose and amylopectin (2 forms of starch), and cellulose.  Compare the structures.
3. Go to Amino Acids and look at 3 different amino acids.  Describe what you see.
4. Go to proteins and look at insulin, hemoglobin, and collagen.  Describe what you see.
5. Go to lipids and look at saturated and unsaturated fatty acids.  Describe what you see.
6. Look at triglycerides and phospholipids.  Describe them.
7. Go to nucleic acids and look at DNA.  Describe it.
