Lesson 3: Newton's Laws
Duration of Days: 10
Lesson Objective
Students will be able to (I can) describe how Newton's Laws can be used to interpret an object's motion. The will apply the Laws to calculate forces acting on an objects.
What is inertia?
What causes objects to accelerate?
Is gravity a force?
Inertia
Acceleration
Force
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.
Math skills to calculate relevant formulas.
The lesson introduces students to Newton's Laws while using real world examples. Students will also perform basic calculations using Newton's second law and kinematic equations.
DOK: 1-2
Jenga game
Centripetal forces of windmills
Rollercoasters
Differentiation between constant velocity and acceleration.
Gravity is not a constant, so it doesn't need to be applied.

Scale, Proportion, and Quantity:
Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth)
Inertia Towers- blocks and note cards
Ramp & Blocks- ramps, blocks, rulers, balls of different sizes
Hero Engine- straws, clay, strings
