Today in class, Mr Paek showed us a clip of the movie Stand by Me. When 4 kids are in the middle of the forest and they decide to go across a small lake. When they get out they discover that they are covered in leeches. Leeches are apart of the Phylum Annelida. They feed on another hosts blood. They often feed on humans blood. Without this supply of blood the leech will die.


After that Mr. Paek told everyone what the homework was and a few announcements. We are going to have a quiz on Tuesday about animal diversity. Mr. Paek said the best way to study for it is to know:
