Backwards Design

Course Objectives

• Primary Objectives- By the next class period students will be able to:
  • Learn and derive the equations for motion in two dimension, also called projectile motion
  • Develop solid and systematic problem solving skills
  • Lay a foundation that is likely to be used in motion in two dimension

• Sub Objectives- The objectives will require that students be able to:
  • Master knowledge of motion in one dimension equation
  • Develop knowledge of vectors to transform equations of motion in one dimension to equations of two dimensions.
  • Use algebra to solve for unkowns specifically quadratic equation

• Difficulties- Students may have difficulty:
  • Making the correct assumptions
  • Remembering equations of motion
  • Choosing the correct angle when working with components of vectors
  • Interpreting results

• Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
  • Given the initial velocity, it is possible to determine the exact angle so that a basketball player make the ball go through the hoop.
  • It is possible to determine the minumum velocity of a stream of water that hits a target at distance 'd' away, provided that you are given the angle of launch.

Model of Knowledge

• Concept Map
  • Differentiate between a scalar and a vector which leads to differentiating between speed and velocity.
  • Distinguish between motion in one dimension and motion in two dimension.
  • Interpret a graph of motion
  • Derive equations for motion in one dimension.

• Content Priorities
  • Enduring Understanding
    • Knowledge of vectors
    • Knowledge of the quantities, displacement, velocity, and acceleration, and how to make valid assumptions with respect to them.

• • Important to Do and Know
    • How to find vector components
    • Assumptions may vary and you are free to choose the assumptions
    • Choose the coordinate system that works the best for you
