#### 1 Describe the motion of the Angry Birds

Angry Birds Space
Free, Free to Try, Paid

I love to use Angry Birds in the classrooom.  I project the game from my iPad on to the screen and have a student or two play a couple of levels.  My questions to the students are, "Describe the motion of the Angry Birds after they have left the slingshot."

Because the students are familiar with the game (or one like it) they can all tell me that the birds fly in an "arc" of some sort.

The next question, "How does the way that you fling the Angry Bird change the arc?"

#### 2 Let's explore the physics classroom

The students are directed to (in small groups or individually) read the sections on projectiles from The Physics Classroom.

From their reading they are to summarize with 4 points they thought were the most important or instructive.

I have them list their summarized points and share them with the rest of the class.

#### 3 Tracking the Motion of a Projectile - Introduction

Vernier Video Physics is a very powerful app that allows students to track (frame by frame) the motion of actual projectiles.

I set up the Vernier Video Physics app on my iPad and use it to record the motion of a tennis ball thrown across the classroom.

I then use an Apple TV to show the student how to use the app to track the motion of the ball, frame by frame.  I then show them how to get the equations of the motion in both the vertical and hozitonal directions with the app.

#### 4 Tracking the Motion of a Projectile - Student Application

So I have students break up into small groups and using some sort of ball (tennis, basketball, baseball, football) throw it and use their device to record the motion of the ball.  It takes a little while for the students to get the hang of this but once they do it is fun and easy.

They use the app to create equations for the motions in both the horizontal and vertical directions.
