Teacher+View+-+Week+3

=**Week 3 -** **Two-dimensional motion**=

**Gain attention**
Stroboscopic images of projectiles – Ask what the images have in common? Play Scorched Earth-like game against computer or online with a classmate – get students to interact early and often with a multiplayer game. Students need expand their projectile intuition to become better players.

**Inform learners of objectives**
Extend one-dimensional model to two Explore the what and why of parabolic flight Calculate air time and distance traveled

**Stimulate recall of prior learning**
Review one-dimensional model using freefall and return to sender examples. Review and vote on best student questions from the previous week

**Present the content**
Movie – Understanding Projectile Motion independence of motion page and Scribd reading - Graphing Quadratic equations and parabolas

**Provide "learning guidance"**
Aiming at falling target, visualizing projectile range as a function of launch angle, two dimensional time graphs showing parabolic motion vs. 1D free fall. 2D projectile simulation - same as previous session, but the angle is no longer fixed to 90 degrees. Students will work backwards and define a parabolic equation based on data from the simulator.

**Elicit performance (practice)**
Students will pick two locations in their neighborhood (to prevent escape velocity) on google maps or equivalent and compute the launch velocity necessary to send a message canister to the next location? They should be aware of what angle and launch velocity they are choosing and be able to pick configurations that results in the fastest and slowest time, highest height, and softest impact?

**Provide feedback**
Immediate feedback from simulation. Feedback from other students and the game itself.

**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 this session. Create 3 questions and solutions for submission to an end of course guidebook. (will be voted on). They must be creative!
