Whale Unit (and the Arctic)

Monday, March 26th, 2012

Have you ever started a unit and then something else unfolds?  Well this is a unit I started to put together on the Arctic.  You might even recall that we covered Antarctica for a couple of days to lead up to this unit. The more we got into it, the more this turned into a full blown study of whales!  We spent more than a week reading, doing experiments and learning to draw to these magnificent creatures. (That’s LD’s drawing of an Orca/killer whale to the left.) I’ll condense all we did/learned into a few posts.

We learned a lot about whales this past week.

  • Did you know that the blue whale is the largest animal ever to have lived? It is bigger even than the largest dinosaur!
  • Did you know that whales can drown?
  • Did you know that the first ancestors of whales lived on land?
  • Did you know that the bones in a whale’s flippers are arranged like a hand?
  • Did you know that dolphins are a type of toothed whale? This website goes on to explain in more detail that those toothed whales that less than 9 feet are called dolphins and porpoises, those more than 9 feet (such as the Killer Whale) are considered whales. Interesting! I didn’t know that!

As always we started our unit off by reading a few books over the course of several days. As with all her books, the Gail Gibbons book was full of fantastic information easily understandable to the kids.  While I read the kids drew and colored. I printed out some coloring sheets for ED.

LD wanted to learn how to draw a killer whale and a blue whale.  The instructions I linked to were just great. Meanwhile DD decided she wanted to draw a dolphin.

We learned that there are two main types of whales baleen and toothed whales.  We sorted through some whale cards I found at Homeschool Share. I put a T and B on the back of the cards (for toothed and baleen) and let the kids sort through those a number of times.  Then I brought out a toob of whales and we matched the plastic critter to the cards (as much as we could, that is).

We did an experiment that shows how the salty water in ocean affects buoyancy. (I reminded the kids why the ocean was salty – this activity we did here.) We took two large bowls of warm water (about  4 1/2 cups in each) and added 1 cup of salt to one of the bowls.  We added a raw potato to each bowl. Although you can’t tell in this picture because the water is so clear  the potato in plain water sunk to the bottom while the one in salty water floated.

On Thursday I’ll share a few more of the activities we did relating to whales.

Ocean Unit:

At the beginning of the year we did a unit on the ocean. We did other activities related to the ocean and ocean animals then as well.  I also made various printables (such as the ocean animal math game or vertebrate-invertebrate sort cards pictured to the left) and you can browse through these pages to see if there’s something of interest if you’re doing an entire unit on the ocean:
