Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.
Clarification statement: Examples of practical problems could include the impact of collisions between two cars, between a car and stationary objects, and between a meteor and a space vehicle.
Assessment boundary: Assessment is limited to vertical or horizontal interactions in one dimension.
Assessment
What assessment of MS-PS2-1 might look like on a NY state exam.
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of four levels.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-PS2-1.
NGSS Dimensions
Performance expectation MS-PS2-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Constructing Explanations and Designing Solutions
- Apply scientific ideas or principles to design an object, tool, process, or system.
- PS2.A: Forces and Motion
- For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law).
- Cause and Effect
- Cause and effect relationships may be used to predict phenomena in natural or designed systems.
