2025 Utah Rural Schools Conference

The presentation is on 3 dimensional science lessons.In Why the Moon Doesn’t Yeet into Space, students explore how gravity and inertia work together to keep the Moon in orbit around Earth. Using the Earth–Moon system as an anchor phenomenon, students investigate the driving question: What keeps the Moon from falling into Earth or flying off into space?Students begin by observing a simulation of the Moon orbiting Earth and sharing initial ideas. They then build background knowledge by reading about gravity and inertia and connecting these concepts to familiar experiences, such as a passenger continuing to move forward when a car suddenly stops. Through discussion and guided questioning, students deepen their understanding of inertia as forward motion and gravity as an attractive force.To model orbital motion, students use marbles and paper plates with gaps to represent gravity and inertia. As marbles roll around the plate and then exit through the opening, students observe how the marble continues in a straight line when the “gravitational pull” is removed. By testing marbles of different masses, students evaluate how well the model represents real orbital motion and identify its limitations.Students synthesize their learning by drawing and explaining a model that shows how gravity and inertia interact to keep the Moon in orbit. The lesson emphasizes developing and using models, identifying system interactions, and explaining unobservable mechanisms, aligning with Utah SEEd Standard 6.1.2 and NGSS expectations.
