NGSS Performance Expectations addressed in this unit:
MS-PS2-1 : Apply Newton’s third law to design a solution to a problem involving the motion of two colliding objects.
MS-PS2-2 : Plan an investigation to provide evidence that a change in an object’s motion depends on the sum of the forces on the object and the mass of the object.
HS-PS2-1 : Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
HS-PS2-2: Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.
Essential question about phenomenon/unit:
- What happens to the brain during a collision?
- How can Newton's first law of motion be used to explain what is happening to the brain during a collision?
- How can Newton's second law of motion be used to explain what is happening to the brain during a collision?
- How can Newton's third law of motion be used to explain what is happening to the brain during a collision?
- How is momentum conserved in a collision between two objects.
Unit Introduction and Initial Models
Where Am I Going?
Students will develop a model to explain what happened to Anthony’s brain during a concussion.
How will I know When I'm There?
1. Use Newton’s three laws of motion to visually explain what happens to the brain during a collision.
2. Explain how momentum was conserved during a collision.
Cross-sections of the Brain with CTE
Cross-sections of Anthony's Brain
Creating an Initial Model
Create a model of what is happening to Anthony's brain during his many collisions that resulted in him having CTE.
