Study Sheet
This
exam takes place on Tuesday, June 16th at 1:00. You should be in the classroom at 12:45 at

tape.
This
exam is geared for one hour, but you have up to 2 hours to complete it. When you are finished, you are free to
leave.
We
studied 3 main units of Science:
Ecosystems, Chemistry and the Earth’s Crust. The Science Probe 7 Textbook was our main
resource.
Section 1: Matching (20 marks)
You
will match words to their definitions from any of the 3 main science units.
Section 2: Multiple Choice (25 marks)
You
will answer 20 multiple choice questions covering concepts from the 3 main
science units.
Section 3: Short Answer (20 marks)
You
will write on ONE topic chosen from a selection of 3. You will be asked to write about your
knowledge of that topic as well as include any charts or diagrams which may be
associated with that particular unit.
