Tutorial Overview
• This will be a shortened tutorial as I am
currently in a Video Conference with some
teachers from around Rockyview.
• Progress reports are being sent out this week.
Please have your Key Parents e-mail me to

Summary
• Organisms can reproduce Sexually or
Asexually
• This spreads importance characteristics
among an organisms’ offspring.
• Some inherited traits are positive, some are
negative.
• Humans can use technology to influence
the breeding of some organisms.
• What do you think? Should humans use
technology to influence the breeding of
organisms?
Things to do;
• Complete Lesson #5
• Work on lessons #6 and 7.
• Perform “Survival: The Ultimate Advantage”
page 52 to see another example of
adaptations helping an organism to be
successful in an ecosystem.
• PREPARE FOR THE UNIT REVIEW QUIZ!
