Ei E: A Stick in the Mud: Evaluating a Landscape Lesson 3 Part 2

Students use maps to study the erosion along a riverbank over time and conduct controlled experiments to determine how soil compaction around a foundation affects the foundation's strength. [7:20]

A storybook introduces the engineering challenge and context. In this story, Suman, a boy from Nepal, learns about geotechnical engineering as he helps evaluate a site for a TarPul. [13:09]

Students think like geotechnical engineers as they take core samples of a model building site and decide how deeply the pier foundations for a model skyscraper should be anchored into the soil. [11:40]

Evaluating Needs and Creating Criteria: Students determine the needs of the plant and the consumer for which they are designing their plant packages. [9:57]

Students use simple machines and spring scales to determine how much force is needed to move a standard load and think about the ergonomics of using each machine. [11:25]
