  1. Forces & Motion 8th Grade Physical Science

  2. Objectives • Forces • Define • Give examples • Draw force diagrams • Big Ideas • Unbalanced forces cause motion • Newton’s laws help predict motion

  3. Think-pair-share What is a force? List specific examples.

  4. Types of Forces "Types of Forces." Types of Forces. Web. 16 Apr. 2013. <http://www.physicsclassroom.com/Class/newtlaws/u2l2b.cfm>.

  5. Types of Forces Trefil, James S., Rita Ann. Calvo, and Kenneth Cutler. McDougal Littell Physical Science. Evanston, IL: McDougal Littell, 2006. Print.

  11. Think-pair-share Does an object always move when a force acts on it? Demonstrate…

  12. Fnormal Fgrav Fgrav Does It Move? Fnormal Fapp Fgrav

  13. 3-2-1 Review Jot down: • 3 types of forces • 2 different force diagrams • 1 question you have

  14. Lab Activity "Forces and Motion: Basics." PhET. Web. 17 Apr. 2013. <http://phet.colorado.edu/en/simulation/forces-and-motion-basics>.

  15. Lab Activity Discussion • Compare PhET results • Big ideas?

  16. BrainPOP – Newton’s Laws "Newton's Laws of Motion." BrainPOP. Web. 17 Apr. 2013. <http://www.brainpop.com/science/motionsforcesandtime/newtonslawsofmotion/>.

  17. Apply Newton’s Laws • 1st Law • With partner/group • Create basic demonstration • Materials found around room • Create force diagram • Share in ~5 minutes

  18. Apply Newton’s Laws • 2nd Law • Discuss with partner • Rocket acceleration/fuel amount? Trefil, James S., Rita Ann. Calvo, and Kenneth Cutler. McDougal Littell Physical Science. Evanston, IL: McDougal Littell, 2006. Print.

  19. Apply Newton’s Laws • 3rd Law • Discuss with partner • Action/reaction forces? • Interaction diagram… Trefil, James S., Rita Ann. Calvo, and Kenneth Cutler. McDougal Littell Physical Science. Evanston, IL: McDougal Littell, 2006. Print.

  20. More 3rd Law… Trefil, James S., Rita Ann. Calvo, and Kenneth Cutler. McDougal Littell Physical Science. Evanston, IL: McDougal Littell, 2006. Print.

  21. Newton’s Laws Describe Motion Trefil, James S., Rita Ann. Calvo, and Kenneth Cutler. McDougal Littell Physical Science. Evanston, IL: McDougal Littell, 2006. Print.

  22. 3-2-1 Review Jot down: • 3 – Newton’s 3 laws, in your own words • 2 – examples of laws being applied (any) • 1 – question you have about Newton’s Laws
