They discovered that penguins stay warm in two ways. One way was by making a huddle. Small groups of children made a huddle. They then switched spots and noticed how much warmer they felt when they were in the middle of the huddle.
The students also learned that penguins stay warm because they have blubber. Students each put one hand in a bowl of ice and the other hand in a bowl of ice while wearing a blubber mitt (made with Crisco shortening). The hand with the blubber mitt was cozy and warm even in ice. The first-graders also made an awesome flip book of penguin facts to enjoy at home!
