Note: Symbols designate activities where there are options about which activities to do:

 Repeating activities: The same activities are also in the Animals and Decomposers units. If you have already taught these activities in another unit, do not teach them again unless you specifically want to do them as a review with your students.

 Turtle symbols indicate more and less demanding activities. See http://media.bscs.org/carbontime/files/Turtles_07.05.16-1.pdf.
