Experimental Design Lesson
How can experimental design influence the outcome of scientific inquiry?
 * PBI Compelling Question ** :

Part I
A. Begin by going to the URL: @http://phet.colorado.edu/sims/projectile-motion/projectile-motion_en.html B. Spend 5 minutes exploring how the flash based applet works. You may wish to ask yourself: - What variables can I alter while exploring projectile motion using this applet? - How do I make measurements using this applet? What can I measure? - What are the limitations of this applet? //Other simulation tools are listed below, however for today's activity we will be Physics based//
 * I. Exploring projectile motion using a flash based applet ** 5 minutes

A. Next, you will form collaborative, investigation groups in order to conduct an inquiry based experiment on projectile motion. Get into your group (2-3). Your group will develop a hypothesis based upon your initial exploration using the applet and then develop an experimental protocol to test the hypothesis. B. Go to your group page and begin your experiment. Complete Part 1 of your Group Page.
 * II. Form investigation groups and design an experiment //30 minutes// **

Group 1 - // Will Evaluate Group 2 // // **Will Conduct the Experiment of Group 3** // Variable: Projection Angle

Group 2 // Will Evaluate Group 3 // // **Will Conduct the Experiment of Group 4** // Variable: Speed

Group 3 - // Will Evaluate Group 4 // // **Will Conduct the Experiment of Group 1** // Variable: Mass

Group 4 // Will Evaluate Group 1 // // **Will Conduct the Experiment of Group 2** // Variable: Diameter

Part 2 //10 minutes//
A. After completing your experimental protocol, ask another group to provide suggestions about your experimental protocol. B. The collaborating group should enter their suggestions in Part II of your Group Page. In turn, your group should provide constructive criticism regarding their experimental design. C. After the peer review group is finished making suggestions on your Group Page, your group should make changes to the experimental design based upon their constructive criticism.
 * Collaborate on the experimental protocol. **

Part 3 //20 minutes//
Next, another group (the investigational group) in the room will conduct the experiment. Choose a group and ask them to conduct the experiment and then complete Parts 3-4 on your Group Page.
 * Conduct the experiment. **
