1. Acceleration Nation What Factors Affect Acceleration? Starring: Kenneth O’Rourke and Christopher Warner

2. Objectives/Goals Distinguish the difference between velocity and acceleration. Describe motion using words, graphs, and equations. Describe fundamental scientific and technological concepts that could solve practical problems. Identify and use the elements of scientific inquiry to solve problems.

3. Lesson Plan Overview 1. Previous Learning Assessment 2. Physics Content 3. Lab exercise 4. Math Content/ Post Lab

4. 1. Previous Assessment Basic algebra and graphing Distance vs. Displacement Distance vs. Time Graphs Displacement vs. Time Graphs Average Speed/Instantaneous Speed Average Velocity/Instantaneous Velocity Pre- assessment Quiz Pre-assessment answers

5. 2. Physics Content A.Student preconceptions and examples B.Definition of acceleration/ Practical examples C.Mathematical description D.Lab Preview

6. A. Student Preconception Questions Students are asked to describe how they view acceleration.  Possible answers: speed, moving fast, etc. Lead students to working definition of acceleration.

7. B. Definition of Acceleration and Examples Acceleration - changing velocity, positive or negative change; changing direction is included in this description Examples  Have students move around the classroom  Physics Classroom webpage showing car accelerating/decelerating Physics Classroom  Demo: Marble moving up ramp and down ramp. (Negative acceleration and positive acceleration.  Demo: Circular motion showing constant speed, changing velocity, and a positive acceleration

8. C. Mathematical Description a = (final velocity - initial velocity) time elapsed Have students manipulate formula to isolate variables. (PowerPoint)(PowerPoint) Practice Problems (answers) Practice Problems (answers)

9. D. Lab Preview Demonstrate how equipment works Define expectations. (Lab Design Structure)(Lab Design Structure)  Develop a method to measure and test acceleration, determine how variables affect acceleration, take measurements, and show data graphically. GET THEM TO INVEST IN SOME OUTCOME! Create table of variables with students. Create table Discuss nature of science  Multiple testing  Collaboration  Peer review to minimize error

10. 3. Lab Exercise Plan for advanced levels of design vs. basic levels of design. Follow Lab Report Rubric (Pennfield Middle School Lab Report Rubric) (Pennfield Middle School Lab Report Rubric) Ensure appropriate amount of guidance facilitates science inquiry.

11. 4. Math Content/Post Lab Graphing  Show examples of graphing (previous velocity vs. time graphs) Show examples of graphing  Graph sample data from student labs  Calculations using the data Solve for acceleration, final velocities, initial velocities, and time Relate calculations to problems and making predictions.
