In this lesson, students will investigate objects’ appearances in varying levels of light to help them construct an explanation that objects can only be seen when light is available to illuminate them. Students will discuss why objects look different in a dark room and graph their preferences for sleeping with a light on or off. Then, they will investigate how an object’s appearance changes in different lighting conditions in small group centers. Finally, they will model the moon’s path around the sun to see how light from the sun causes the moon’s appearance to change as it orbits Earth. At the conclusion of the lesson, students will use their experiences as evidence to explain that light is essential for sight.
