6th Grade (SCI) Physical Science Standards
[PS2] Motion and Stability: Forces and Interactions

##### SCI-MS.PS2.04 Use evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

Clarification Statement: Examples of this phenomenon could include the interactions of magnets, electrically-charged strips of tape, and electrically-charged pith balls. Examples of investigations could include first-hand experiences or simulations.
Disciplinary Core Ideas
PS2.B: Types of Interactions Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass-e.g., Earth and the sun.

## Student Learning Targets:

• I can

### Reasoning Targets

• I can compare the amount of gravitational forces acting between objects.

### Skills (Performance) Targets

• I can explain how every object exerts a gravitational force on every other object.

• I can
