=**Week 2 - One-dimensional projectile motion**=

**Gain attention**
Letterman video of falling objects Maybe show footage of freefall and “big shot” rides at amusement parks. Base jumping? Pogo sticks? Show reaction on people's faces as they become projectiles in one-dimension!

**Inform learners of objectives**
Projectile motion along one axis - what goes up, must come down. Understand the influence of gravity. Application of F=MA. Compute velocity and air time of objects at impact Compute launch velocity to reach specified height

**Stimulate recall of prior learning**
s, v, and a can all be represented by Vectors. Make sure they understand how they are related in the real-world. acceleration is change in velocity is change in position Review and vote on best student questions from the previous week. Why were they good problems?

**Present the content**
Video - 6. Newton lays down the laws of force, mass, and acceleration. Online reading

**Provide "learning guidance"**
Freefall and return to sender examples. Students use the INET to find fun locations and heights from which to drop items of their choosing. Examples should be unique. Early posters will have an advantage.

**Elicit performance (practice)**
Fill in variable fact sheet – each student fills in another dimension/variable of the answer. There are fewer degrees of freedom as the fact sheet gets filled in. Students should both submit values that they have experimented with and compute outcomes based on evidence.

**Provide feedback**
Simulation provides immediate feedback. With the angle locked at 90 degrees, movement is restricted to the vertical plane.

**Assess performance**
Self assessment - if student doesn't pass the online quiz, we suggest more practice. They are encouraged to contact the teacher with specific problems if they don't score as well as they would like.

**Enhance retention and transfer to the job**
Have students create a review log of what they have learned Create 3 questions and solutions for submission to an end of course guidebook. (will be voted on). Be creative!
