  1. Acceleration NationWhat 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 • Previous Learning Assessment • Physics Content • Lab exercise • 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 • Student preconceptions and examples • Definition of acceleration/ Practical examples • Mathematical description • 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 • 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) • Practice Problems (answers)

  9. D. Lab Preview • Demonstrate how equipment works • Define expectations. (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. • 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) • Ensure appropriate amount of guidance facilitates science inquiry.

  11. 4. Math Content/Post Lab • Graphing • Show examples of graphing (previous velocity vs. time graphs) • 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.

  12. Where can I find all this great stuff! • http://www.sas.upenn.edu/%7Ekennethp/physicspowerpoint.html • There are links to every assignment and PowerPoint linked to on the page • Feel free to use and alter any of our created work to suit your instructional goals.

  13. Standards • http://www.pde.state.pa.us/a_and_t/lib/a_and_t/Science_Anchor_Introduction.doc • Standards covered in the lesson

  14. Assessments • Pre-assessment • Acceleration Work Sheet • Lab Report • Graphs • Physics Class Room
