					Reviewing Cell Parts Day 3
 By the end of this period – you should be able
  to label the parts of a cell in a diagram and
              explain their functions.
  Hmwk: Complete the cell plate coloring and
            the cell part review sheet.
               Today’s Agenda
• All of the following belong to Part 2 of your Challenge 1.
• Watch the video #1 on cells.
• See if you can label the two cells in your portfolio
  (use the book!) I will check off the last few groups – you
  need to take a brief oral quiz before I stamp off part 3.
• Next, you will have time to work on your cell parts
  review – you will need the textbook for this – write your
  answers on the back of the sheet.
• Then, begin coloring your animal and plant cell color
  plate. You must color the word to match each part.
• Go back to your journal cover – can you complete the
  labeling?
    Welcome! Please pick up
challenge 2 and take out your cell
parts study guide and color plate.

Pop Quiz!
Welcome! Please find your new
 seat on the seating chart and
 pick up a challenge 1 packet.

  Everyone should be finished and have
        part 2 stamped off today.
  Hmwk: Quiz over challenge 1 will be

Microscopes!
Top 4 Rules for Microscope Use
1. Carry the microscope with one hand under the
   base and one on the arm.
2. Always pull the cord out by the plug not by the
   cord.
3. Always store the microscope with the stage all
   the way down, on scanner, with the cord
   wrapped.
4. Always clean and dry slides – do not leave
   them lying around the room or on your stage.
        How to determine total
           magnification
• Multiple the eyepiece (ocular)
  magnification by the objective lens
  magnification.
• Part 2: In your journal……
              Learning to focus
1.   Wet a piece of lens paper with water and clean your
     objective and eye piece lens – dry with lens paper only.
2.   Pick up a fixed slide of human muscle tissue.
3.   Clip slide under stage clips.
4.   Turn the nosepiece to the scanner objective.
5.   Use the Course adjustment to bring it into focus.
6.   Move the slide around on the stage until you are looking
     at a specific spot.
7.   Turn your nosepiece to low power and turn the course
     adjustment if you need to.
8.   Turn the nose piece to high power and turn the fine
     focus just slightly if needed.
Practice
How to make a wet mount
How to draw what you see
  Newsprint “e” – Title
                          1. Use a petri dish to
                             trace a circle that
                             represents your
                             microscopes field of
                             view.
                          2. Write a title.
                          3. Write the
                             magnification.
                          4. Take time to sketch
                             exactly what you see
                             in your micrscope.




   High Power – 400X

Make a wet mount of the letter e
• Answer questions 3-11.
• When you are done – Start on Part 5
• When you are ready to get your additional
  sample – remember it must be paper thin
  – do not use chunks of skin, blood, scabs,

  ends in your hair, check out a thread from
  your sweater etc.
Please pick up challenge 1 and

   Challenge 1 will go into the
gradebook next time – after next
    class Challenge 1 is late.

       Hmwk: Get ready for the
      challenge 1 quiz next time.
 Prokaryotic and Eukaryotic Cells
• Part 5 – Look on pages 114 of your
  textbook to answer questions 1-6.
Part 6: Animal Vs. Plant Cells
Plant Cells
Plant cells stained with Iodine
Human epithelial cells stained with
            Iodine
