Year 12 Biology: Gas Exchange differentiated unit
 You may work individually or in a small group (maximum of 3 students). However, each
student must be responsible for their own learning and must attempt ALL activities
and tasks.
 You may complete the tasks in any order, but they must be completed by the due date.
After which revision will commence for the unit test.
 After the completion of each task, mark your own work using the answer folder
provided and ask your teacher to sign the appropriate box in the table.
 Patterns of life textbook and the ESA Y12 Bio textbook (teal coloured) should stay in the
classroom unless they have been specifically issued to you. You must bring your
Patterns of life workbooks to class.
 You are responsible for making sure that you understand each topic – ask if you need
help, but C3B4ME (see 3 other students about your question before you see me)
The powerpoints and worksheet are available on Miss Jan’s wikispace (http://miss-jansscience-wikispace.wikispaces.com/Gas+Exchange) and on the Student Resources folder
