Lesson
Description: This lesson helps students to understand or review
their understanding of global warming, the green house effect
and climate changes. This information is necessary before completing
some of the other modules found in the Willow Biomass curriculum.
The lesson makes use of the Internet and works on the skills of
technical reading and summarizing of scientific information. This
is one of the new emphases of the state and national standards.
There are step-by-step instructions provided to assist the students.
Learning
Outcomes:
Students
will be able to:
- Access the Internet and search for information on a given topic
- Read and summarize a technical article
- Define the key terms listed on the student worksheet
- Explain the greenhouse effect and be able to draw a picture
showing the key points
- List some impacts of global warming in the world
Materials
Needed:
Choose one of the following methods depending on how familiar
your students are with the internet and how to use it.
Method
one: Using the computer lab. For these activities scheduled
time in the computer lab will need to be arranged. Make sure all
students have access to their computer codes to enter the system
before the lesson begins. This will save a great deal of Head
ache the day of the lesson. Some schools also require permission
from parents to access the Internet so be sure to check on the
schools policies.
-Computer lab with a computer per every two or three students
-You may find it helpful to have a computer set up for yourself
with the computer overhead projector to model the steps as you
go along.
Method two: In class session with LCD projector and one
connection to the Internet
Using a computer that has access to the Internet and a classroom-viewing
screen that projects the computer image for the class to view
all at once.
-Computer
with access to the Internet -Extension cords (possibly)
-Overhead screen -Overhead marking pens
-Computer overhead projector LCD -Copies of the activities for
each student
Method
three: Combination LCD lesson and computer lab work
Complete the first page of the activity as a classroom unit and
the follow up worksheet in the computer lab. Follow the hints
provided in method 1.
Time
Requirements: Approximately 90 minutes
Non-blocked classrooms: Recommendation use method 3 above introducing
the lesson to the whole class one day and completing the worksheet
the next day or during the "lab" period.
Blocked
or a double period: Recommend method 1 or 2 depending on your
student's abilities and computer facilities. If students finish
early, check the accuracy of their work, and then have them complete
the drawing assignment included in the worksheet, ask them to
find more detail on the topic and summarize their findings, including
the website.
