Step 4. After your group has worked together on this you must each research if you think your piece of pollution is a positive or negative effect on the life forms in that water source.

All members have found out what their pollution is (point source/nonpoint source) and figured out whether is has a good or bad effect, everyone will get 3 points.

Only two of the members have completed both parts of this step and receive 2 points.

Only one member of the group does all of their work and everyone gets 1 point.

No one in the group did any of the work needed everyone will get 0 points.
