Clean Streams, Creeks and Ponds

We have been learning about streams and comparing the fearures of clean streams and those which have been affected by external influences. Today Mel McCoglan told us about stream life and she showed a great video about a stream which had some pollution and some clean parts.
After that we played a game where we tried to score points by cleaning up Old Bernie's Pond. Some of us were able to get to the end, score 7 points and win a certificate. There is a link for people from room 5 to have another try to clean the pond. I hope you can remember the username and password. I'll write it up at school in case you need to copy it. Have fun.
