<p> Models and Design Storyline FOSS 5th/6th Grade</p><p>Big Idea(s): Models are used to explain how systems work and how they are constructed. Engineers use scientific knowledge to design and build useful things.</p><p>Investigation 1: Black Boxes Investigation 2: Hum Dingers Sub Concept I: A model is a representation or Sub Concept II: Scientists construct physical explanation of a system or interaction that cannot. models to demonstrate how something works be observed directly. or how it is constructed.
