# Whale Science

Add Crisco to a zip lock plastic bag – then put another bag inside out in the zip lock bag. Then Zip lock them together (so the Crisco is in between both baggies). Have the child place one hand inside the plastic bag and their other hand in a regular zip lock bag. Put both bags in ice cold water. They will see how whales can live in Arctic water. The Crisco is the whales “blubber” and keeps them warm. My sister told me about this and my 3 and 4 year olds love it! Enjoy!

For a wonderful outside (or use the halls of your center) lesson in measurement, buy a 100 ft. rope or twine. Tell the children that the ball of twine that you have is the same size as the largest mammal in the ocean–The Blue Whale. Take the children to a place that will stretch 100 ft, and have them pull the twine until they reach the end. They will be squealing at seeing how large a 100 ft. Blue Whale is. Expand with predictions: How many children would it take to make a blue whale? How many blocks? How many paper plates? Could a Blue Whale fit in your car? Your house? etc.

I made a large whales head and a large whales tail out of bulletin board paper. I mounted the tail outside our classroom door and then we measured out 100 feet down the hall and put up the whales head. The children got a real appreciation for how big the blue whale actually is. To add to the activity we measured each child with strips of adding machine tape and put them up in the hall, one after the other (length wise) to see how many children it took to be as long as the whale.
