Theme: Sport Science Title: Understanding the Physics of the Ollie! Overview In Pulse of the Planet episode #4362, Paul Schmitt describes the science of the skateboard trick known as the “Ollie”. The program also explains how the “Ollie” got its name. In this lesson, students will explore the physics of the Ollie! Grade Level 6-8 Subject Matter Science Duration 2 Class Periods National Standards Addressed Physical Science Content Standard B - MOTION AND FORCES If more than one force acts on an object along a straight line, then the forces will reinforce or cancel one another, depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object’s motion. Physical Science Content Standard B - TRANSFER OF ENERGY Energy is a property of many substances and is associated with heat, light, electricity, mechanical motion, sound, nuclei, and the nature of a chemical. Energy is transferred in many ways. Objectives In this lesson, students will learn about the physics involved in the skateboard trick known as the Ollie. Students will use Pulse of the Planet episode 4362 and two web sites to investigate the physics of the Ollie. Students will then demonstrate their understanding giving a skateboard science presentation featuring the physics of the Ollie.

Hold up a skateboard and say OLLIE! Ask students why you are holding a skateboard and saying OLLIE? Some student(s) should know that an Ollie is a skateboard trick. If not, tell the students that an OLLIE is a skateboard trick that involves skateboard science especially physics. Tell students that at the end of this lesson they will conduct a presentation that communicates the “how to” and “physics” of an Ollie. 2. Introduce and play Pulse of the Planet episode 4362 titled Skateboard Ollie. Option: Have a student demonstrate an 3. 4. 5. 6. 7. 8. 9. Ollie in class. An Ollie can also be viewed at the American Institute of Physics web site http://www.aip.org/dbis/stories/2007/17079.html Explain to the class that they are going to be working in teams of 2-3 to research, plan, and present to the class the steps and physics in an Ollie. Divide the class into their small groups. Give each student a Presentation Guide. Guide students through the Presentation Guide. Allow students to research, plan, and prepare their presentation. Circulate the class providing support and monitoring student progress. Students share their presentations with the class. Discuss the presentations and how the Ollie Concept Bank was integrated into the presentations. Close the presentations by making a connection between the skateboarding and the science! Play Pulse of the Planet 4362 and tell the students that you tricked(Ollie reference) into learning about skateboard science! Congratulate your students on a job well done! Handouts Presentation Guide Your Name_______________________________ Partner Name(s)_______________________________ POP 4362 Sport Science: Ollie Presentation Guide Directions: Research information from POP 4362 and 2 web sites to compile information about the physics needed to do an Ollie. You will use your research to create a presentation about how to do an Ollie and the physics involved. You must correctly use the terms in the Ollie Concept Bank in your presentation.
