Learning the parts of a microscope and experimenting with magnifications.
Goals/Objectives:
Students will learn the 8 specific parts of
the Electron light microscope. They then
will understand about different magnifications, and be able to draw a
conclusion about the perception seen through the microscope.
1. Students will fill in
microscope work sheet during class demonstration.
2. Students will retrieve a
microscope from the shelf and show proper lifting and carrying techniques while
traveling back to their seats.
3. Students will turn in the 2nd
page of their completed packet. This
will measure their understanding of the material.
Connections:
SC-H-3.1.1 Cells have particular
structures that underlie their function.
Every cell is surrounded by a membrane that separates it from the
outside world. Inside the cell is a
concentrated mixture of thousands of different molecules that form a variety of
specialized structures. These structures
carry out specific cell functions.
SC-H-3.1.6 In the development of multicellular organisms, cells multiply and
differentiate
to form many specialized cells, tissues, and organs. This differentiation is regulated through the
expression of different genes.
SC-H-2.3.4 Evidence
for one-celled forms of life, the bacteria, extends back more than 3.5 billion
years.
Context:
This lesson is preparing the students for the
unit on cells. By becoming familiar with
the microscope and the different parts I hope that each student will be able to
gain a full understanding of what they are looking at. Once the students are comfortable with each
magnification I hope to move with a faster pace, expecting the class to observe
and evaluate different slides. This will
simplify the last lesson, which covers amebas, and other single celled
organisms.
Materials Needed:
- 1
microscope per 2 students
-
10 random slides
-
10 slides with the letter E on them
-
1 worksheet per student
-
web references
-
labeled
diagram of a electron light microscope
-
picture
of an electron light microscope
Procedures:
1. I will introduce the class
to the electron light microscope. Giving
some brief history and interesting facts.
A worksheet will then be past out.
2. I will then demonstrate the
proper lifting/carrying techniques used for the microscope.
3. I will go over the three
magnifications and explain the parts of the microscope.
4. The class will follow along
with their worksheet and fill in the parts of the microscope.
5. Each student will pair up
and one member of the group will retrieve a microscope from the cabinet,
demonstrating the techniques just taught in class.
6. The students will follow the
directions of the worksheet and explore the electron light microscope.
7. I will travel around the
room in case there are questions or concerns.
8. While moving from station to
station I will randomly ask questions concerning the students
slides.
9. Once the worksheet is
finished I will take them up and notify the class of the quiz tomorrow on the
microscope parts.
Student Assessment:
The students’ assessment
will be based on the rubric that can be found on my web page. I will provide a copy of the rubric when
handing out this assignment. I strongly
suggest that all students pay close attention to the criteria because that is
what their grade will be based upon.
