# Phabulous Physics

## Unit Summary

In this unit, students fully investigate linear motion. After reviewing essential mathematics concepts, students are introduced to laws of motion, velocity and acceleration, vectors, and Newton's Laws using a series of online simulations. After students have a thorough understanding of these basic concepts, they prepare brochures illustrating a real-world problem related to motion that answers the Unit Question, How do the laws of motion describe everyday events? Students illustrate the problem, show how to solve the problem using physics principles, and use spreadsheets to enter data and graphically show some aspect of the solution. With a firm understanding of these principles, student groups create a survey designed to gather information from the community about a given road hazard. The community data is used to prepare a slideshow presentation that will be presented to the city planners. The goal of the presentation is to persuade the leaders to make changes to a dangerous section of road or intersection.

## Assessment Processes

View how a variety of student-centered assessments are used in the Phabulous Physics Unit Plan. These assessments help students and teachers set goals; monitor student progress; provide feedback; assess thinking, processes, performances, and products; and reflect on learning throughout the learning cycle.

## Instructional Procedures

Preparing for the Unit
This unit presumes students have solid mathematical skills. Students should refresh their skills through the introductory homework assignment. An answer key is provided for class review. The homework serves the dual purpose of reviewing conversion skills, and providing the students and teacher with feedback about the students’ readiness for the physics unit to come. Provide additional practice if necessary.

Introducing Linear Motion
Introduce the physics of linear motion with the support of the following online simulations:

PhET Simulations*

Forces and Motion

Ramp: Forces and Motion

These online simulations cover the Unit Questions, How do the laws of motion describe everyday events? and Can the motion of any object be predicted? The simulations also address the Content Questions, How are speed and velocity related? and What are Newton's Laws of motion?

Students can either explore simulations in the computer lab or as homework, with discussion to follow in class to address the unit and content questions. Where necessary, review simulations and provide students with additional examples from the textbook or Internet resources to reinforce these basic concepts.

At this point, give a short quiz assessing conversion skills, vector analysis, and forces. A quiz answer key is provided. The quiz serves the dual purpose of reviewing physics principles, and providing the students and the teacher with feedback about the students’ readiness for the completion of the next assignment—developing a digital product. Provide additional practice if necessary.

Creating a Publication
Model the upcoming independent physics project through a whole-class practice activity. Lead the class as they work out a linear motion problem related to traveling locomotives. Guide students as they develop a paper-and-pencil solution and verify their solution. Have students copy the traveling locomotives data into a spreadsheet and create a graph to represent their data (for example, see spreadsheet with graph). If students have not used spreadsheet software to enter data and create graphs, provide them with whole-class guidance using a projector and/or provide them with the spreadsheet help page.

After students complete these activities, show the class the locomotive problem brochure to give them a sample of the final product.

Group students into pairs. Instruct each pair to create a brochure that illustrates a real-world problem that is related to motion and answers the Unit Question, How do the laws of motion describe everyday events? as well as the broader Essential Question, Can all the events around us be anticipated and explained?

To ensure students understand the assignment and how they will be assessed, distribute the brochure scoring guide and discuss the project criteria in detail. In partners, ask students to assess the locomotive problem brochureusing the rubric. Then as a class, discuss students’ ratings and try to come to consensus about the ratings given for the various traits.

Have students navigate to Projectile Motion*, a PhET simulation that encourages students to fire various objects out of a cannon while manipulating variables to learn about projectile motion. After students find the solution, and hit the target, ask them to create a digital product of their learning (for example, a blog, wiki, narrated slideshow, videocast, screencast, or digital poster). The product should include the following elements:

• Statement and explanation of the problem
• Illustration of the problem (screenshot)
• Explanation of how launch angle, initial speed, initial height, mass, and air resistance affected the projectile’s range, motion path, final height, and time
• Key kinematic equations and a mathematical solution to the problem
• Graph showing a mathematical representation of the problem

Have students prepare a five minute presentation about the projectile problem and its solution, supported by their digital product. Make sure to clarify or cover any additional material that is crucial and not answered by the individual presentations.

Ask students to provide feedback to their peers about the presentations using the oral presentation rubric. Allow time for partners to review the feedback and incorporate suggestions into their next presentation.

Beginning the Project
Have students create blog entries describing information obtained during the course of the project. Review entries throughout the project to check for understanding, provide feedback, and adjust instruction as necessary.

Tell the students that they will take on the role of members of a transportation safety advocacy group. Their task is to create and deliver a presentation to the city planners proposing changes to a dangerous section of road or intersection, and answer the Unit Question, How can understanding the laws of nature make our lives better or safer?and the broader Essential Question, Can all the events around us be anticipated and explained?

Ranking the Hazards
To help students compare, prioritize, and analyze different hazardous locations, introduce them to the Visual Ranking Tool. Before you use Visual Ranking with your students, examine the Visual Ranking Web site and become familiar with the tool.

Set up a project and add teams in the teacher workspace. Assign the students to groups and lead the class through a discussion of safe driving. Ask the class, “Since you have begun driving, how many of you have personally been in or know someone who has been in an accident?” After some discussion, have the students offer the names of sections of roads or intersections that they feel are unsafe. After brainstorming five to seven dangerous roadways, enter these into the teacher workspace of Visual Ranking. Have the groups log in to their Visual Ranking student workspace and rank the locations from most hazardous to least hazardous. Students should explain their rankings using appropriate principles of motion.

Circulate through the room while the groups work, taking anecdotal notes, questioning for understanding, and providing feedback as necessary. After all groups have finished ranking the list, have each group compare their ranking with other groups’ rankings. Lead a class discussion of why the rankings might be different. Students should then individually record information in their journals. If possible, invite the head of transportation public safety to participate in the ranking and include these results in the discussion.

Creating a Survey
Either assign or have student groups pick a dangerous section of road or intersection from the list generated previously in class. Student groups create a survey designed to gather information from the community about their given road hazard to obtain public information. Have students create their survey using an online survey maker or a blog to post their questions and collect information. A list of potential survey and blog sites is included in the unit resources. A sample survey* and a sample blog* were created as examples for this unit. Review these sites with students as models for expectations and to answer any questions. Send letters home and solicit parent responses. If possible, see if your local newspaper will include a brief description of your class project and include the survey or blog site link for the class. Tell the class that feedback obtained through the site will be included in the final presentation. As feedback is obtained, have students include the data in their journals.

Conducting Research
Allow students time to conduct research on their chosen hazardous roadway. Have the class look through local newspapers and resources as well as conduct Internet research. Have students write their information in their individual journals.

Schedule conferences while students are conducting research to answer questions, monitor their progress, and provide additional help as necessary.

Creating a Causal Map
To help students investigate cause-and-effect relationships, introduce them to the Seeing Reason Tool. Before you use Seeing Reason with your students, examine the Seeing Reason Web site and become familiar with the tool.

Set up a project in the teacher workspace and make sure the teams are assigned. Have students look at a sample traffic casual map in Seeing Reason that looks at the many factors that affect road safety. Remind students that their map will look very different because it will focus on the physics involved in a hazardous roadway or intersection. Have teams log in to their Seeing Reason student workspace. Ask student teams to create a causal map of the factors that make their road or intersection hazardous. As responses are obtained from the student’s Web site, have them modify their causal maps and add this data to their student journals. Encourage more research, and incorporate any additional information into the team causal map. Use the comments portion of the tool to provide feedback to the group as they work on this portion of the project.

Creating Presentations
Have students create and deliver a 10 to 15 minute slideshow presentation outlining a given section of road or intersection. Have students use kinematic equations to explain the problem and their proposed solution to the road hazard. The presentations answer the Unit Questions, How do the laws of motion describe everyday events? and Can the motion of any object be predicted? as well as the bigger Essential Question, Can all the events around us be anticipated and explained? To ensure students understand the assignment and how they will be assessed, distribute the project scoring guide and presentation guide. Discuss the project criteria in detail with the class. Remind students that they will take on the role of members of a transportation safety advocacy group. Their task is to make a presentation to the city planners proposing changes to a dangerous section of road or intersection. Make sure to clarify any project questions and remind students to incorporate the peer feedback from their previous presentation as they plan and practice for their final presentation.

Completing Final Presentations
On the day of presentations, tell students that they will take turns making presentations and asking questions about each team’s road hazard and the research behind it. When the audience is asking questions, they take on the roll of city planners trying to determine the best use of limited transportation funds to change a dangerous section of road or intersection. When answering the questions, the presenters take on the role of members of a transportation safety advocacy group. Invite administrators and teachers with planning periods during this class to participate.

After all presentations are complete, debrief the activity and summarize the suggestions. To wrap up, pose the Unit Question, How can understanding the laws of nature make our lives better or safer? and the broader Essential Question, Can all the events around us be anticipated and explained? Facilitate a class discussion that targets the study of roadways and intersections and then draws some final conclusions about the study of linear motion in the real world.

As a final reflection, ask students to complete the self-assessment on group contribution form.
