Unit 1: Technological Inventions and Innovations

Overview

Big Idea Inventions and Innovations are a result of evolutionary technological development and systematic research and development. Teacher’s Note: Big ideas should be made explicit to students by writing them on the board, reading them aloud, and/or posting them on worksheets associated with the lessons. For deeper understanding, have students write the Big Idea in their own Engineering Design Journal (EDJ), using their own words, if they choose. Purpose of the Unit This unit is designed to teach students to analyze the historic significance of technological advancements and to gain an understanding of the influences of technology on history. The use of technology has had profound effects on the course of history. As such, most inventions and innovations are the result of an evolutionary process and have students understand how a series or refinements leads to an improvement in a technological device; that new technologies create new processes and have students be able to explain how a change in technology would change the process of creating a product; teach the students all the factors that lead to changes in technology; and that research and development is a problem-solving approach used by companies to prepare products and systems for the marketplace.

Science: Benchmarks for Science Literacy (AAAS, 1993/2009)1 Nature of Technology/Design and Systems

● All technologies have effects other than those intended by the design, some of which may have been predictable and some not. (3B/M 2a)

● The value of any given technology may be different for different groups of people and at different points of time. (3B/H2)

Nature of Technology/Issues in Technology

● The human ability to influence the course of history comes from its capacity for generating knowledge and developing new technologies—and for communicating ideas to others. (3C/H6)

● Societies influence what aspects of technology are developed and how these are used. People control technology (as well as science) and are responsible for its effects. (3C/M7)

Unit Objectives

Lesson Big Idea Objectives Lesson 1. The History of Technology (6 Hours)

People are better able to understand the world around them when they explore how people of all times and places have used their unique skills to innovate, improvise, and invent.

Compare and contrast early steel and iron tools from the Iron Age with earlier bronze and stone tools. Research a technological device from the Middle Ages that produced long-lasting effects on technology and society. Explain that the Industrial Revolution saw the development of continuous manufacturing, sophisticated transportation and communication systems, advanced construction practices, and improved education and leisure time. Describe societal events from the 1900s that led to progress in science and invention. Select one of the following areas of technology and explain how technology changed the way people live and work: agriculture, manufacturing, sanitation and medicine, warfare, transportation, information processing, and communications. Demonstrate how Information Age devices are used to process and exchange information.

Lesson 2. Inventions and Innovations: An Evolutionary Process (5 Hours)

Inventions and innovations are the result of an evolutionary process through a series of improvements and refinements.

Interpret charts and graphs that illustrate the rapidly increasing rate of technological development and diffusion. Approximate and interpret rate of change from graphical and numerical data. Support the statement that most technological developments have been evolutionary, the result of a series of refinements to a basic invention, through an electronic presentation. Present the evolutionary history of a technological device, specifically mentioning the original inventions and the series of refinements to that invention that led up to the given technological device. Describe a technological innovation that resulted when ideas, knowledge, or skills were shared within a technology, among

Assessments There are no unit level assessments. Lessons in the unit are assessed using:

Presentation Items Performance Rubrics Selected Response Items Brief Constructed Response Items

Specific tools are incorporated into each lesson as Supporting Files. EbD™ Video There are many ways to hook students, but one great way is through the EbD™ , or a video introduction to the unit and/or lessons. This allows visual cues while helping students to start thinking about what they already know about the Big Idea. The frog puts the content in context by using themes (Custer/Daugherty/Meyer, 2010; Hacker/Rousseau/Devries, 2009). Engagement is the first step to introducing a lesson. Engagement involves activating students' prior knowledge about the subject of study. In order to activate prior knowledge, the teacher must hook the students in and make them become interested in the lesson. The EbD MediaRichedition™ of this Course Guide, available to those teachers and schools in the EbD™ Network, includes the opportunity for teachers to submit frogs that are shared with other teachers in the Network.
