New from No More Boring Science - The sun appears to rise over the horizon each day. As we wake up and get ready for the day, the sun seems to begin traveling across the sky. Is the sun actually moving? Are we moving? We know that the earth rotates around an imaginary line, or axis, extending from the planet’s north to south pole. This causes the sun to appear to move across the sky as the earth spins. Looking down at the earth from above the north pole, the earth appears to spin counterclockwise. This spinning motion causes us to experience day and night. In ancient times, people of many cultures constructed simple devices to study the sun’s apparent motion. One such device was a primitive form of sundial called a “shadow stick.”
This lab demonstrates the path the sun takes across the sky. It is appropriate for students from as young as 5th grade all the way to 12th graders. It can also be used to explore angle of insolation for the New York Regent's Exam.
