Keeping Warm In the Cold

Subject Area





In this lesson, students will be able to explain that wearing a coat helps keep you warm because it blocks your body’s heat from moving away from you to where it’s cold. The teacher discusses whether a thick or thin jacket helps students stay warmer in cold weather. Students see a demonstration in which a container with warm water is placed in cold water. The warm water cools down quickly. Students then design and test a “coat” for the container to keep the water warm longer. Students watch an animation explaining why a coat helps keep them warm in the cold.

    Science (2015) Grade(s): 1


    Design a solution to a human problem by using materials to imitate how plants and/or animals use their external parts to help them survive, grow, and meet their needs (e.g., outerwear imitating animal furs for insulation, gear mimicking tree bark or shells for protection).

    Students know:
    • How plants use their external parts to survive, grow and meet their needs.
    • How animals use their external parts to survive, grow and meet their needs.
    • People can imitate how plants and animals survive and grow to help us solve a human problem.


    Students are able to:
    • Design a device that attempts to solve a human problem.
    • Use materials to imitate external structures of plants and animals.


    Students understand that:
    • The shape and stability of structures of natural and designed objects are related to their function.
