FOREST CONSERVATION
Is sawdust an efficient alternative fuel to wood?

Learning outcomes

• By the end of the unit for this Project, you will
  be able to
• Tell where the main forests are found worldwide.
• Explain the importance of forests and the impact
  their destruction will have on all life.
• Collect, record and analyse data obtained by
  telecollaboration.
• Compile a list of different types of fuel used in
  various countries including South Africa.
• Systematically test the processes of burning wood
  and sawdust in order to compare them on common
  properties.
• Explain why poor people cut down trees for
  firewood and suggest alternative sources for
  fuel.
• Understand the relationship between man and the
  environment

Forests - GoingGoing. Gone???

• Worldwide, our forests are disappearing at an
  alarming rate.
• Why are so many trees being cut?
• How will this loss affect us?
• Why do the poor people in villages rely on
  firewood?
• Is there an alternative fuel to firewood which
  will not have as big a negative impact on the
  ecosystem?
• What can be done to help prevent destruction of
  our forests?

Project Tasks

• In order to arrive at answers, the following
  activties must be carried out.
• Brainstorm on
• Importance of forests
• Types of cooking fuel used and if any of them
  have a direct impact on our forests.
• Construct a K-W-L chart on Sawdust.
• Record all observations during a trip to the
  lumber mill.
• Carry out experiments to determine which one is
  the more efficient fuel - wood or dawdust.
• Communicate and work collaboratively with your
  respective groups in the countries assigned to
  them.
• Communicate your final findings to your peers in
  the form of a Powerpoint presentation, Chart
  display.
• Keep a record of the daily activities done using
  a journal.

Assessment

• The following will be used to assess you. This
  can be used as a guide to help you develop your
  project successfully..
• Scientific Report Rubric
• Poster and Powerpoint Rubric
• Collaboration Rubric

Timeframes

• All preliminary work regarding telecollaboration
  should be done before the start of the project
• Plan the project and prepare the class for the
  forthcoming project.
• Contact the liaision person and finalize the
  grade, class codes of the groups and countries
  you will be collaborating with.
• Place a large map on the notice board and
  indicate on it where in the world the partner
  classes are located
• Brainstorming on forests and - 2 weeks
• collection of fuel data from villages
• Visit to lumber mill
• Experiment to compare the burning - 1 week
• efficiency of sawdust and firewood
• Record and analyse data discuss
• Final presentation (Ppt slideshow Chart) - 1
  week
• Submission of daily activity log

Resources

• The following lists some of the resources that
  can help the learners. Learners should also be
  encouraged to find out and list accurately their
  our own resources and not depend entirely on what
  the facilitator has provided.
