Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.

Safety Data Sheet

In this lab, students will explore the materials that biomedical engineers use when creating prosthetic devices. They will first investigate the physical properties of various metals, ceramics, and polymers to understand how they differ, and determine which materials would be most suitable for use in a hip replacement prosthetic. Students will then engineer their own prosthetic arm that meets certain design requirements and mimics the functionality of a real hand. Kit contains enough materials for 15 groups. Teacher's Manual and Student Study Guide copy masters are included.
