Summary

Students are introduced to the concept of a dam & its potential benefits, which include water supply, electriđô thị generation, flood control, recreation và irrigation. This lesson begins an ongoing classroom scenario in which student engineering teams working for the Splash Engineering firm kiến thiết dams for a fictitious client, Thirsty County. This engineering curriculum aligns lớn Next Generation Science Standards (NGSS).

Engineering Connection

Human-made dams are important in our modern life. Civil engineers và thành phố planners compare the benefits, cost & environmental impacts khổng lồ determine whether a community could benefit from a dam.


Learning Objectives

After this lesson, students should be able to:

Interpret và evaluate data khổng lồ formulate conclusions.Underst& the needs for và impacts of dams & reservoirs.Describe how the use of giải pháp công nghệ provides essentials và luxuries for everyday living.

Educational Standards

Each vinaanh.com lesson or activity is correlated lớn one or more K-12 science, giải pháp công nghệ, engineering or math (STEM) educational standards.

All 100,000+ K-12 STEM standards covered in vinaanh.com are collected, maintained & packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).
