#### 1 attention getter

Have the students watch the video to activate prior knowledge and have a baseline attachment to sporting activities.

Student Instructions

Watch this video. While the formulas are physics and you won't need to know them until you take that class, it's a fun video.

#### 2 Exploration

Activity: Investigating

Materials needed:

Football field or other field that has measurements.

Soccerballs - 1 per group

Student Instructions

1. Kick a soccerball as many times as needed to get video of each of the following:

a. Qty 2: Without moving the ipad, the soccerball must stay on the screen

b. Qty 3: Set the ball on the 5 yard line. Different people kick the ball to go different distances. The ball needs to be in the screen at all times

#### 3 Assessing

Activity: Assessing

There are 2 separate items here: one to show parabola, constant horizontal speed, changing vertical speed, angle of take off.

The other is to explore distance vs. time vs. velocity.

Student Instructions

Using the two videos with the soccer ball in the screen without moving the ipad:

Using the draw tool, mark a horizontal line every .1 sec.
Take a screen shot.

Using the draw tool, mark a vertical line every .1 sec. Take a screen shot.

Draw a line that shows the path of the soccer ball. Take a screen shot.

Using the three videos of the ones that are for distance:

Note the time of initial contact and initial distance yard line. Note the time when the ball hits the ground and the distance yard line.

#### 4 Analysis

Have the students work together to finish the worksheet.
