Throughout this unit you have learned about gravity and the ways that it has influenced the interactions of celestial bodies.

Now you will use the knowledge you’ve gained to write a movie scene about gravity’s effects on celestial bodies.

The director of the movie has assigned you the task of critiquing the movie script about space and writing a climax for the movie based on the laws of physics.

Performance Assessment Requirements Your movie script should demonstrate an understanding of: • gravity’s role in the formation of the solar system • the formation of planets in the solar system • the growth of planets in the solar system • the modeling of stars outside our solar system • the structure of the Milky Way galaxy • the different type of galaxies _____ Step 1: Evaluating the Current Scene On Handout: Script About the Sun’s Gravity, annotate the script by circling and explaining the errors. Then, in the space below, critique the current script overall. Does this story work? Is there any way to change it to make it gravitationally accurate?

_____ Step 2: Brainstorming a New Scene With your group, brainstorm ideas for a new storyline and write out the details for three of them.

Describe each new plot you propose and then explain how gravity is involved.

Plot 1 Description:

Gravity’s Role in Plot 1:

Plot 2 Description:

Gravity’s Role in Plot 2:

Plot 3 Description:

Gravity’s Role in Plot 3:

Proficient (2 points)

Emergent (1 point)

Wrote a script for a movie that fully describes all components representing relevant forces and physical objects involved in the event being modeled.

Wrote a script that neglects to fully describe all components representing the relevant forces and physical objects involved in the event being modeled.

Did not describe any components representing forces or physical objects involved in the event being modeled.

Designed a written model that represents the relationships and interactions between parts of the solar system accurately.

Represented the relationships and interactions between parts of the solar system, but without a clear understanding of how they influence each other as a system.

The interactions between parts of the solar system were not represented.

Used appropriate understanding of the relationship between Earth and the universe.

Discussed the relationship between Earth and the universe, but with mistakes.

Did not apply the relationship between Earth and the universe to the plot.

Identified how gravity governs the interactions of celestial objects in the solar system.

Identified how gravity governs the interactions within the solar system, but with some mistakes.

Did not identify how gravity governs the interactions within the solar system.

Earth and its solar system are part of the Milky Way galaxy, which is one of many galaxies in the universe.

Earth and its Solar System The solar system appears to have formed from a disk of dust and gas, drawn together by gravity.
