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.
