Freddy the Fish...water quality

Back into my classroom....we are learning about watersheds.  Boy have we had fun! One of the activities that I love is the Freddy the Fish Story from the WUP center in Michigan.  In this activity, you read aloud a story about Freddy the Fish (see the green sponge?) and his travels down the watershed.  He starts in a nice cool, clean stream.  As he travels he encounters all sorts of pollution - from too much sediment, to litter, fertilizer, etc..
The materials you pour into the tank are easy to find at home and are earth friendly for when you pour the water out as well.  We used Koolaid mix, basil, syrup, coffee sludge, soil, etc...
The students really enjoyed this demonstration and were able to visualize the effects humans have on water quality.  When we were finished, the students then went back to their science notebooks and drew a picture of before and after.  They were able to add their opinions as well as noted observations about the quality of water and the effect on Freddy (he dies, by the way!).
Great lesson!
