10/12-10/22

• Mon 10/12:  Food Lab due through turnitin.com today!!  Questions on Biochemistry Review?  Test on Friday 10/16.  See Review Sheet.  Start Cells.  Introduce Cell Theory and work through the rest of the worksheet using IB text books.  
• Wed 10/14:  1st Period will be taking the PSAT.  Other classes will continue to work on Cell Worksheet and Cell Model Project.
• Fri 10/16:  Cell Test.  Intro to Microscopes and Magnification.
• Tues 10/20:  Using Microscopes to look at cork, onion, and pond water. 
• Wed and Thurs 10/21-10/22:  Parent-Teacher-Student Conferences!!
• Fri 10/23:  No School.

Food Lab due Mon 10/12

See your hand-out for instructions on the write-up, but essentially you need to include 1) The question: "Which organic molecules are present in (your 4 foods), ie pretzels, banana, cooked potato, and plain cheerios?"  2)  Procedures:  how your group organized itself.  Be specific, but you don't have to write it out as every little step  3)  Results:  you need to present all the results for your group, but I don't want you to simply cut and paste each other's results.  Discuss them at your table and present them in your own way.  Include initials of the student who took the data.  4)  Conclusions:  as a result of the results, which organic molecules were detected in each food?  Include limitations of the tests.  What cannot be concluded due to test limitations?   5)  Evaluation:  discuss the quality of your results.  What worked well?  What could have been more reliable?  How could you make the results more reliable.  What results do you trust more than others?  Cite weaknesses of the procedures and suggest improvements both to the way you perform the tests and in how you could have organized your work as a group.

Make it your own!  You will be submitting through turnitin.com.
