Wonderful Water

Walt: identify things and what it will look like if the water is clean or not clean.

We learnt about new words like Algae witch is the green slime that sticks on stones in creeks. I also learnt that stone fly's, may fly's and caddis fly's only stay in very clean water and that is a good sign. Snails, worms and animal poo would be a bad sign because if it is in the creek than the water would get dirty.
