Hardness of Materials - Introduction

This six-page guide from Edmonds Community College outlines a laboratory activity demonstrating the differences in properties between different materials. Students observe these differences through recording the height a ball bounces off different surfaces. This activity engages students with concepts of property differences between materials of the same class. Students utilize data analysis skills and observe the role of operator method on results. This activity is designed for high school and introductory college classrooms, and requires 20-30 minutes with discussion. This guide includes the following sections: Student Learning Objectives, MatEd Core Competencies Covered, Materials and Supplies Required, Curriculum Overview, Module Procedures, and Evaluation Packet.
