1. Topic-
|
| Introduction to Microscopes |
| |
|
2. Content-
|
| Parts of a microscope, how a microscope functions, proper care of
a microscope, developing microscope skills. |
| |
|
3. Goals: Aims/Outcomes-
|
1.Learn the parts (including their function) of a compound light
microscope.
2.Learn how to properly care for a microscope.
3.Learn how to properly use a microscope to observe a specimen:
A. Demonstrate the proper procedures used in correctly using the compound
light microscope.
B. Prepare and use a wet mount.
C. Determine the total magnification of the microscope.
D. Explain how to properly handle the microscope.
E. Describe changes in the field of view and available light when
going from low to high power using the compound light microscope.
F. Explain why objects must be centered in the field of view before
going from low to high power using the compound light microscope.
G. Explain how to increase the amount of light when going from low
to high power using the compound light microscope.
H. Explain the proper procedure for focusing under low and high power
using the compound light microscope. |

4. Objectives-
|
Students will be able to name the parts of a microscope correctly.
(They should get the correct answers on their worksheet and should
be able to verbalize the different parts of a microscope when asked.)
Students should be able to calculate the right magnification every
time.

| |
|
5. Materials and Aids-
|
| Laptop, overhead projector, PowerPoint, microscopes, microscope
slides (clear and premade), cover slips, beaker of water, and student
handouts. |
| |
|
6. Procedures/Methods-
|
|
A. Introduction-
1.Introduction PowerPoint
2.Students fill in their worksheet as I go over the parts of a microscope. |
| |
|
|
B. Development-
1.I will model proper microscope care.
2.I will model how to properly magnify an image using a microscope
(by demonstrating using the microscope).
3.I will explain how to calculate the total magnification. |
| |
|
|
C. Practice-
1.Students will practice using the microscope.
2.Students will make a wet mount slide.
3.Students will observe protists using pre-made slides. |
| |
|
|
D. Independent Practice-
| Students will complete a lab worksheet throughout the activity. |
| |
|
|
E. Accommodations (Differentiated Instruction)-
| I will help struggling students during the lab and modify their
lab if needed. |
| |
|
|
F. Checking for understanding-
1.I will ask students questions as they work.
2.I will check their packets to see if they are getting the answers
right.
3.I will check their microscope when they have a specimen magnified
to make sure that they are doing it correctly.
4.I will inspect their wet mount slide and check for air bubbles. |
| |
|
|
G. Closure-
1.Students will clean their slides and put away the pre-made slides.
2.Students will demonstrate that they know how to carry and put a
microscope away by doing it.
3.We will discuss the conclusion questions at the end of the period. |
