Partner Resource Traveling Sound PostedJune 18, 2019 Posted byTeach Engineering Team https://www.teachengineering.org/activities/view/cub_energy2_lesson05_activity2 Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theatres.

Partner Resource Design Step 1: Identify the Need PostedJune 18, 2019 Posted byTeach Engineering Team https://www.teachengineering.org/activities/view/cub_creative_activity1 Students practice the initial steps involved in an engineering design challenge. They begin by reviewing the steps of the engineering design loop and discussing the client need for the project. Next, they identify a relevant context, define the problem within their design teams, and examine the project's requirements and constraints. (Note: Conduct this activity in the context of a design project that students are working on, which could be a challenge determined by the teacher, brainstormed with the class, or the example project challenge provided [to design a prosthetic arm that can perform a mechanical function].)

Partner Resource Powerful Pulleys PostedJune 18, 2019 Posted byTeach Engineering Team https://www.teachengineering.org/lessons/view/cub_simple_lesson05 Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a pulley can change the direction of a force, the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple / combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes. Read More Q&A0
