Build Working Models With Household Items
 Lesson Focus - Develop a working model of a nail clipper.
Lesson Synopsis - Students learn the basic principles of engineering design and model building.
Age Levels - 10-18.
Objectives
Explore the basic principles of engineering design.
Learn how to build a model of a simple machine.
Explore how a simple machine such as a nail clipper works.
Lesson Activities - Students design and build a working model of a nail clipper. Through the process, students explore simple machine construction and the process of model making, as well as learn about simple machines - a nail clipper is an example of a first class lever. This activity can be completed in a single 45 minute course block.
Anticipated Learner Outcomes - As a result of this activity, students should develop an understanding of:
Principles of engineering design
