=This page was last updated on January 11, 2017= =UNIT NAME:= = "Microscopes and Cells" =



OBJECTIVES:

 * ===Given an advanced secondary microscope, students will focus it clearly;===
 * ===Given a microscope or labeling diagram, students will identify the parts and their uses;===
 * ===Given a microscope, students will describe and/or demonstrate how to move and focus it safely;===
 * ===Given a micrsoscope and prepared specimen slides, students will draw the contents of the slide consistent with teacher-provided guidelines;===
 * ===Given clean microscope slides, coverslips, and dissection kit, students will prepare dry mound and wet mount slides;===
 * ===Given digital microscopes with oil immersion lenses, students will focus them correctly and produce photographs labeled consistent with teacher-provided guidelines.===
 * ===Given biological samples (i.e.: plant parts, microorganisms, human cheek cells) students will prepare slides, visualize, and draw or photograph the specimens;===
 * ===Given prepared slides and/or cell diagrams, students will correctly identify organelles and their functions;===
 * ===Given the foregoing specific laboratory activities and exemplars/rubrics, students will prepare formal laboratory reports.===

=Plant cell structure and function=
 * ** Detailed notes describing the structures within plant and animal cells. **
 * ** All eighteen organelles and structures in these notes are required for tests and quizzes. **

==Review for Unit Test--Cellular Structures / Processes & Microscopy==


 * ====ALL CLASSES should complete Pages 1-2;====
 * NO MORE THAN 2 identical reviews will be accepted -- you may prepare a review with only 1 partner.
 * Work effort will be collected for potential **extra credit** value at the tme of the test;
 * ====The source for the review (and test) is chapter 7 of __Miller/Levine Biology__====
 * It is assumed that you consult classroom notes, videos, and conversation as well for your preparation.
 * **ASK QUESTIONS in class if you do not understand any concept or detail required by the review!**

=Hypothesis for This Lab Report (Paraphrase if Necessary -- DO NOT PLAGIARIZE!)= = Can You produce a High-Quality Lab Report? = = Sure You Can! = (Here's an exceptionally good student effort on this lab report from the 2010-11 school year.)
 * (Complete, step-by-step directions and requirements for microscopic drawings)**
 * READ THEM AT LEAST TWICE before beginning your project
 * Note that District guidelines for devaluation of late assignments will be STRICTLY implemented.
 * // If the magnification (power) of a microscope is increased, then: //**
 * **// field of view is reduced; //**
 * **// depth of field is diminished; //**
 * **// and more light is required //**
 * // ... because high power objective lenses have narrower openings and steeper curvature. //**


 * This student effort was not improved in any way by the teacher. (Wow!)**

 * // If cells are stained correctly, observed properly, and surrounded with solutions of different tonicity: //**
 * **// internal structures (organelles) may be observed and labeled; //**
 * **// turgor can be altered; //**
 * **// and plasmolysis caused //**

**// ... because water and biological stains diffuse readily across plasma membranes. //**
