Do you know how penguins stay warm in cold climates? We brainstormed about this using the scientific knowledge we’d learned and made a hypothesis about blubber. Darling then tested her/his hypothesis. First we put one hand in the creek and determined that our hands were cold. So cold that it was difficult to keep our hands in the water for very long. Next, Darling put her/his hand in a bag of blubber (or Crisco) and submerged that hand in the creek. Darling noted the result and then made a conclusion about the purpose of blubber and body warmth. We discussed other animals that have blubber, as well.
