Love My Cetaceans!



Grades 1st-3rd dove into the Cetalogy, the study of whales, this past month.  We took some measurements in our hallway to try and understand how big some of these mammals are.  How does a blue whale get so big as to fill our hallway, but it only eats little bitty animals like krill?  Having teeth doesn't help you very much if you are a whale and you eat plankton, but being baleen does!  We investigated the difference in how baleen and toothed whales eat with a comb, toothbrush and a jar filled with water and black pepper and got to see

first hand how the toothbrush (baleen) was filled up with krill (black pepper) while the comb (toothed) hardly caught any.  Then we put our hands in ice water!  Well, first we put a "blubber bag" over our hands to understand how a whale's blubber helps them live in their environment.  First and second graders used the Pebble-go website to research different kinds of whales.  Third grade used many other websites about whales and also found out about other sea life related to whales.  For instance, the cookie-cutter shark that eats small bites from whales and leaves round, scars on a whale's body.
