Thurs Oct 2: Please review our notes and discussion exploring the additional organelles of the eukaryotic plant cell: (a) cell wall, (b) central vacuole and (c) plastids (chloroplasts).   For the remainder we assigned organelles for teh Cell Rap Assignment.

                            Learning Check Thurs Oct 9


Tues Sept 30: Please review our continued notes and discussion exploring organelles of the eukaryotic cell: (m) cell membrane.  Note the membrane's phospholipid bilayer structure, its semi-permeable nature and the Fluid Mosaic Model for the membrane.


Mon Sept 29: Please review our continued notes and discussion exploring the organelles of the eukaryotic cell: (g) lysosomes, (h) vesicle, (i) vacuole, (j) cytoplasm, (k) cytoskeleton, (l) cilia / flagella...to be continued.


Thurs Sept 25: Please review our continued notes and discussion of the organelles of the eukaryotic animal cell: (d) ER, (e) Golgi apparatus, (f) mitochondria...to be continued.


Wed Sept 24: Please review our continued notes and discussion exploring differences between prokarytotic and eukaryotic cells: (c) structure and size, (d) organelles and (e) DNA.  Also review our introduction to the organelles of the eukaryotic cell: (a) nucleus, (b) nucleolus, (c) ribosomes...to be continued.

Tues Sept 23: Questions related to the microscope lab were addressed.  Please review our continued notes and discussion of the types of microscopes: (c) dissecting / stereomicroscope and (d) scanning electron microscope (SEM).  The microscope worksheet was discussed and corrected.  Also review the differences between prokaryotic and eukaryotic cells: (a) Kingdoms involved, (b) presence of nucleus...to be continued.


Fri Sept 18: Students completed a worksheet comparing the various microscope types and uses.  The remainder of the period was provided for students to work on their microscope lab report.


                Microscope Lab Report Due Tues Sept 23

                Including Biological Drawing and Q1-10a


Thurs Sept 17: Please review our notes and discussion exploring the types of microscopes: (a) compound light microscope, (b) transmission electron microscope (TEM), (c) scanning electron microscope (SEM) and (d) dissecting (stereomicroscope).  Most of this information is contained on a handout table.

                Including Biological Drawing and Q1-10a


Tues Sept 16: Please review our notes and discussion exploring how to construct a scale biological drawing.  Students then completed this drawing for the onion cell.


                Microscope Learning Check Thurs Sept 18             

                    Microscope Lab Report Due Fri Sept 19

                Including Biological Drawing and Q1-10a


Mon Sept 15:  Students prepared a wet mount of an onion cell and calculated its biological size.

          Microscope Learning Check - Thurs Sept 18


Fri Sept 12:
Students completed the Learning Check.  Please review the formula for calculating biological size.  We completed a sample calculation and then students used a prepared slide on an amoeba to practice focusing and calculating biological size.  More work with this next day!


Wed Sept 10:
Please review our notes and discussion exploring terms related to the compound light microscope: (a) total magnification & calculations, (b) field of view, (c) depth of field (thread illustration), (d) working distance, (e) resolving power, (f) image inversion, (g) specimen, (h) wet mount (note procedure) and (i) permanent slide.
