Copy of Gravity and Orbits: Student Sheet.docx
DRAFT: Gravity and Orbits - NGSS AlignedLearning Goals:Explain how gravity controls the motion of our solar systemIdentify the variables that affect the strength of gravityPredict how motion would change if gravity was stronger or weakerOpen the Gravity and Orbits Simulation. Investigate the simulation for 10 minutes and write down 5 things that you observe as you manipulate the simulation.______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Explore the presets. How are the variables of vector, velocity, and mass set to produce the following orbits and relationships.PresetVelocity, Mass, and Vector SettingsRelationship ProducedStar, planet, and moonVelocity-Mass-Vector-Star, planet, and cometVelocity-Mass-Vector-Binary StarVelocity-Mass-Vector-Choose another pre-set. Describe how the velocity, mass/gravity, and vector interact to produce an interaction.Select one question to examine with the simulation. Your group may need to rewrite your question using the clarification comments. Formulate a hypothesis from your observations.Question:Observations:Hypothesis:What evidence from the simulation supports your hypothesis?Using the information from the table above, write a summary explaining the relationship between the force of gravity and the motion of objects in our solar system.Use the simulator to try to produce the following interactions:A comet orbiting a star.A comet that escapes a star.A solar system with 1, 2, or 3 planets orbiting a star.A collision. ................
