Get all students to find some garbage around their classroom or outside. They each should have at least one piece. Garbage can include plants (yard waste), liquids, paper, etc..
Have students find the affect strip of paper for their garbage type(s)
Have students stand in a line. First student is mountain top and last student is estuary. Give the first student a bucket and put a tub after the last student (tub can be filled with water to further illustrate that it is the K’ómoks Estuary or other waterbody).
Students pass the bucket down the line and add their garbage to the bucket.
Last student empties the bucket into a clear tub.
Everyone looks at all the garbage that can accumulate in the K’ómoks Estuary or other waterbody and talks about the effect of different garbage on estuary habitat and wildlife.
If there is water in the tub you may want to leave it for some time (day/week/month) and check in periodically to see what is happening to the garbage. If you do this you may also want to ask one student to stir or shake the tub once in awhile.
Have students write what they have learned from this simulation as to how garbage can be a problem in a watershed.
Extend the learning by analyzing which types of garbage break down more readily than others and creating a visual representation, such as a bulletin board or a poster.
Go on a walk and pick up garbage. This could be done around your school or any other location. Project Watershed and other non profit groups organize groups for the Great Canadian Cleanup at the end of September. You could join them or do your own.
