With the worksheets in this lesson, students will understand what elements make up natural and artificial light. Without light from our Sun, the Earth would be cold, dark and lifeless. Light is a valuable kind of energy for all living things. Students will look carefully at the picture in this lesson and circle all the sources of light they see and then decide if they are an artificial light source or natural light source. Then they will look at the pictures on the chart and put a check mark under gives off heat or produces no heat.
