MS-ESS1-1 : Develop and use a model of the Earth-Sun-Moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.

MS-PS2-4: Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

MS-ESS1-2: Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

MS-ESS1-3: Analyze and interpret data to determine scale properties of objects in the solar system.

●  I can create and use a model to explain the seasons on Earth.

●  I can create and use a model to explain the lunar phases. 

●  I can create and use a model to explain the eclipses of the sun and moon. 

● I can explain how gravity plays a role within galaxies and the solar system using a model. 

● I can make a claim about how mass and gravity are related. 

● I can analyze and interpret data and use it as evidence to support my claim. 

1. How are mass and gravity related?

2. How are the planets different from one another?

3. Why do the seasons occur?

4. Why do the phases of the moon occur?
