Green Schools has an outline of Blubber Glove that might be useful here.
I’d consider enhancing this ‘task outline’ with the children’s own questions to bring it into an inquiry learning format as outline in the Framework for Inquiry.
They might look at the thickness of the blubber for warmth, or the material that the blubber is made of, or if smaller hands stay warmer for longer vs larger hands in blubber etc.
