The construction paper is placed in the sun for the day. Then students remove the sun and see that the paper has faded. They are asked to draw some conclusions about the sun. Students are then introduced to the scenario for the task. The Coppertone Company is having a poster contest for first graders.
Students design a poster that tells one way the sun is useful and one way the sun is harmful.
The first exploration uses Windows on Science to help students discover some facts about the sun. Students make some predictions, watch Windows on Science , and then write down what they have learned. In the second and third explorations, students learn about the sun as a source of light through shadows. In the fourth exploration, students learn about the sun as source of heat through an investigation. Students investigate where it is warmer, in the sun or in the shade.
