Students will understand basic definitions of force and related terminology, such as work and energy.

Physical Science Content Standard B: As a result of activities, students should develop an understanding of motions and forces.

Internet access skills; reference skills; Microsoft Power Point software skills.

Procedure with Teaching Strategies 1. Students will research the concept of forces using the references provided. 2. Students will develop a Power Point presentation that defines and explains the nature of forces and cites examples of forces of nature.

One class period should be slated for research and two periods for the development of the presentation. It is beneficial if students are permitted to view each others completed projects, as well.

This assignment should be evaluated for completeness and correctness. A minimum number of slides should be required with a list of necessary terms to be included. Additionally, the insertion of graphics and/or Internet pictures may also be required.

Students will access internet sites and physics references to obtain information about the nature of forces. They will display this information in the form of a Power Point presentation.
