Students also complete Lab Manual pages 57-58. Students use the ball, lamp, and themselves to make a model of how the moon revolves around Earth. The model shows how shadows caused by the sun seem to change the shape of the moon. Actually, the amount of the moon visible from Earth is changed. Students will complete Lab Manual pages 61-62 as they do the activity.
Students construct a sundial shadow maker.
They use the shadow maker to record the position and length of shadow for specific times during a day. They use their observations and collected data to draw a conclusion about the relationships between time of day and position and length of shadows made by the sun. Students will complete Lab Manual pages 59-60 as they do this activity.
