12.000 Solving Complex Problems is designed to provide students the opportunity to work as part of a team to propose solutions to a complex problem that requires an interdisciplinary approach. For the students of the class of 2013, 12.000 will revolve around the issues associated with what we can and must do about the steadily increasing amounts CO2 in Earth's atmosphere.Each year's class explores a different problem in detail through the study of complementary case histories and the development of creative solution strategies. It includes training in Web site development, effective written and oral communication, and team building. Initially developed with major financial support from the d'Arbeloff Fund for Excellence in Education, 12.000 is designed to enhance the freshman experience by helping students develop contexts for other subjects in the sciences and humanities, and by helping them to establish learning communities that include upperclassmen, faculty, MIT alumni, and professionals in science and engineering fields.

Students build a model of the Sun-Earth-Moon system, exploring how the Moon revolves around the Earth, and the Earth around the Sun. Students play a memory game and learn some characteristics about the three objects.

Students will learn about the position of the sun and moon in the sky to develop an understanding of relative distances, the appearance of movement across the sky, and relate it to day and night, Earth's orbit, the spin of the Earth, and the visible shape of the moon.

This activity teaches students on how the day and night occurs. It also teaches the student about the rotation of the Earth and what two people from opposite sides of the world experience at the same time.
