  • What color absorbs more heat?

    I think the jar with ____________ paper will be warmer

    because_______________________________________

    ______________________________________________.

    When we measured the temperature, the jar with the

    white paper was ________ degrees. The jar with the

    black paper was _________ degrees. The water was

    heated using ____________ energy.

  • Lesson !: Wrap 2 identical mason jars with construction paper 1 with black and 1

    with white. Tape closed. Pour the same amount of water in each jar. Have students

    predict in which jar the water will become warmer? Leave the jars in the sun for at

    least 2 hours before measuring the temperature in each. Have students record

    results. Teacher discussion points: Dark surfaces such as the black paper absorb

    more light and heat than the lighter ones such as the white paper. After

    measuring the temperatures of the water, the glass with the black paper around it

    should be hotter than the other. Lighter surfaces reflect more light, that's why

    people where lighter colored clothes in the summer, it keeps them cooler.
