Models are powerful tools for teaching Science as they provide useful simplifications of structures and processes, helping make the unseen visible and the complex simple! Using the ready-to-use materials provided, students first assemble a model to represent the Phases of the Moon that can be used to make predications and communicate their findings to others. The model shows students why the phases of the moon happen and how the Moon orbits the Earth. Your students begin by making their models of the Moon, Earth and Sun. Next, they use their models to look at the phases of the Moon starting with a new moon. It first goes to a waxing phase, to a full moon and then a waning phase back to a new moon. The model covers: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent. The model can also be used to show how the Moon orbits the Earth. Includes enough materials for an individual student to work alone or 2 students to work cooperatively to assemble a paper model. Also includes a comprehensive background information providing opportunities for students to Engage, Explore, Explain, Extend and Evaluate their understanding of the concept. Satisfies NGSS Standards which encourage students to develop & use models to represent structures, systems & processes. Perfect for use at home, in the classroom or lab.
