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

Students will design an experiment to test their hypothesis using the Projectile Motion Online Simulation tool. Students will produce a written critique of their peer group's experimental design Student's will conduct an experiment following a peer group's experimental design Students will engage in a discussion of the process of experimental design
 * Learning Outcomes for this PBI:**

Physics Based Motion Simulation Tool
 * Technology Tools Used:**

= = Lesson Overview

Introduction (Day 1) //5 minutes//
Quick introduction to the objectives and the activities.There will be three groups collaborating on a single experiment. There will be an experimental design group, a peer review group, and an investigational group.

Part I (Day 1)
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?
 * 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 - Arshad, Shan, Fan //Will Evaluate Group 2// //**Will Conduct the Experiment of Group 3**// Variable: Projection Angle

Group 2 - Maggie, Jenny, Shirley //Will Evaluate Group 3// //**Will Conduct the Experiment of Group 4**// Variable: Speed

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

Group 4 - Frank, Yan Jun, Jie //Will Evaluate Group 1// //**Will Conduct the Experiment of Group 2**// Variable: Diameter

Part 2 (Day 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 - (Day 2) - //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.**

Part 4. Results and Discussion - //30 minutes//
The investigational group should now write a short paragraph using scientific writing to explain their findings. Findings will be discussed with the group at large.
