 Homework Central



Thurs Oct 19: Please review our notes and discussion exploring Limits to Cell Size: (1) limits to diffusion, (2) control by nucleus, (3) surface area to volume ration and (4) collisions of reactants.  Students should now have a unit review sheet.

                           Unit 1 Test - Thurs Oct 26

Tues Oct 17: Please review our continued notes and discussion of (2) Active Transport: endocytosis (pinocytosis and phagocytosis) and (b) exocytosis.  We developed a flow chart to organize the concepts related to transport.

                           Osmosis Lab - Due Wed Oct 18                           
                              Unit 1 Test - Thurs Oct 26

Mon Oct 16: Students gathered data for Core Lab #2 - "An Investigation of Osmosis (The Great Potato Experiment)".  Please review our continued notes and discussion of Transport: (1) Passive Transport (c) facilitated diffusion. (2) Active Transport (a) endocytosis...to be continued.

                            Osmosis Lab Due - Wed Oct 18 

Thurs Oct 12: Please review our continued notes and discussion exploring (1) Passive Transport (b) osmosis.  Be able to solve problems related to osmosis and identify conditions of plant and animal cells under osmotic stress (lyse, turgid, crenate and plasmolyze). 

                       
Wed Oct 11:
Students completed the learning check.  Please review our continued notes and discussion of (1) Passive Transport (b) Osmosis.  Note that osmosis involves the movement of solvent (water) from a hypotonic solution to a hypertonic solution until both sides of the cell membrane are isotonic.

Tues Oct 10: Cell Rap presentations were completed.  Please review our notes and discussion exploring Transport in Cells: (1) Passive Transport (a) Diffusion.  Note diffusion applies to the movement of particles (solute) from high concentration to low concentration down the concentration gradient.  This is as a result of Brownian Motion.  Particles involved are small and uncharged such as oxygen and carbon dioxide.

                       Learning Check - Wed Oct 11

Thurs Oct 5:
Please review our notes and discussion exploring the additional Organelles of the Eukaryotic Cell: (1) cell wall, (2) central vacuole and (3) plastids.  For the remainder of the period students presented their Cell Rap.

                          Learning Check - Wed Oct 11

Wed Oct 4:
This class was lost for Student Council Co-Vice President Elections.

                           Learning Check - Wed Oct 11

Mon Oct 2:
Students worked on the "Cell Rap".  This is an activity that requires students to build cell organelles and perform a rap / song that assists in remembering its function.

                           Learning Check  - Wed Oct 11

Fri Sept 29:
Please review our continued notes and discussion of the Organelles of the Eukaryotic Animal Cell: (13) cell membrane.  Note the semi-permeable nature of the membrane, the phospholipid bilayer construction and the fluid mosaic model.  Students were then introduced to the "Cell Rap" assignment.

Thurs Sept 28:
Please review our continued notes and discussion of the Organelles of the Eukaryotic Animal Cell: (7) lysosomes, (8) transport vesicles, (9) vacuole, (10) cytoplasm, (11) cytoskeleton, (12) cilia / flagella...to be continued.

Tues Sept 26:
Please review our continued notes and discussion exploring Organelles of the Eukaryotic Cell: (5) Golgi apparatus, (6) mitochondria...to be continued.  Note how the endomembrane system (cycling of vesicles) takes place.

Mon Sept 25:
Please review our continued notes and discussion of Prokaryotic and Eukaryotic Cells: (3) structure and size, (4) organelle presence or absence and (5) DNA differences.  Also review our introduction to Organelles of the Eukaryotic Cell: (1) nucleus, (2) nucleolus, (3) ribosomes, (4) endoplasmic reticulum...to be continued.

Thurs Sept 21:
The graded microscope learning check was returned.  Please review our continued notes and discussion of the various Types of Microscopes: (3) dissecting microscope and (4) scanning electron microscope.  Students completed a worksheet examining uses, similarities and differences between microscope types.  Also review the differences between Prokaryotic and Eukaryotic Cells: (1) organisms included, (2) presence / absence of nucleus...to be continued.

Wed Sept 20:
Please review our notes and discussion exploring the Different Types of Microscopes: (1) compound light microscope, (2) transmission light microscope...to be continued.  Note similarities and differences.  Refer to the handout.

        Compound Light Microscope Lab Report Thurs Sept 21

Tues Sept 19:
Students made a wet mount of an onion cell in order to calculate its biological size and to complete a to scale biological drawing.  Excellent lab work folks!

     Learning Check - Parts of Microscope & Functions Wed Sept 20
           Compound Light Microscope LAB REPORT Thurs Sept 20

Fri Sept 15:
Please review our notes and discussion exploring Estimating Biological Size.  We completed sample problems.  Also review our discussion and samples of how to construct Scale Biological Drawings. 

   Learning Check - Parts of Microscope & Functions Wed Sep 20

Thurs Sept 14:
Students completed the Learning Check.  Students viewed the letter "e" to illustrate image inversion and overlapping threads to demonstrate depth of field.  We discussed the procedures for making a wet mount and students practiced this in the lab.  Finally students practiced focusing the microscope on a prepared (permanent) slide of an amoeba.

Tues Sept 12:
Please review our continued notes and discussion of Core Lab 1 "The Compound Light Microscope".  Note microscope parts and functions, calculations related to total magnification and the definitions of field of view, depth of field, working distance, resolving power, image inversion, specimen and the wet mount procedure.

               Learning Check - Scientists Thurs Sept 14

Mon Sept 11:
Please review our notes and discussion exploring the scientists that contributed to The Cell Theory: (1) Hooke, (2) Leeuwenhoek, (3) Brown, (4) Schleiden, (5) Schwann, (6) Braun and (7) Virchow.  Know the 4 parts of the Cell Theory.  We then introduced Core Lab #1 "The Compound Light Microscope".  Be able to label the parts of the microscope and know their functions...to be continued.

                  Learning Check - Scientists Thurs Sept 14


Fri Sept 8:
We introduced Unit 1 "Matter and Energy for Life" which explores the basic unit of life; the cell.  Please review our notes and discussion exploring the debate surrounding the origin of living cells: spontaneous generation vs biogenesis.  Note the work of each of the following scientists and which theory their work supported: (1) Aristotle, (2) Redi, (3) Needham, (4) Spallanzani and (5) Pasteur.

Wed Sept 6:
Welcome to the course.  I am looking forward to working with you throughout the year.  Today class lists were reviewed and textbooks were distributed.  Students were also provided with a new course descriptor.  Use this website to track homework and topics covered in class.
