Engineering Design in the Next Generation Science Standards Using a Picture Book and Online Tools to Teach Kids (and adults) about Engineering Design Original activities created and assembled by: Kirk Robbins & Tom Hathorn Table of Contents Page 3-5 Description Overview of Engineering Design and Those Darn Squirrels Guide (PD or K-5 activities 6 PD page for identifying Engineering Design components in Those Darn Squirrels 7 PD page or student page for identifying Constraints & Criteria 8 Images of bird-houses for an optimizing activity 9-12 Worksheets to guide Engineering Design of Marshmallow Challenge 13-17 PD pages as a variation on the Marshmallow Challenge- Participants start with a vague challenge and must ask questions to clarify criteria and constraints. During the challenge, some participants act as “anthropologists” and observe the engineers for evidence of a variety of engineering “look fors”. 2 Overview: The purpose of this guide is to assist a teacher, lecturer, or professional development provider in designing a learning experience on Engineering Design. Objectives: a. Learners will be able to understand and recognize the components of Engineering Design The Engineering Design Process o Define Problems o Develop Solutions o Optimize Solutions b. Learners will also be able to describe constraints and criteria in order to define the problem in an Engineering Task. Next Generation Science Standards by Grade Band: Grades K-2 K-2-ETS1-1 Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool. K-2-ETS1-2 Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem. K-2 ETS1-3 Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs. Grades 3-5 3-5 ETS1-1 Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost. 3-5 ETS1-2 Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. 3-5 ETS1-3 Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. 3 Pre-Reading (Launching Engineering Design) 1. Today we are going to learn about engineering. Does anyone know what an engineer is? What do you think engineers do? 2. Watch What is Engineering? Video youtube.com/watch?v=bipTWWHya8A http://www.youtube.com/watch?v=bipTWWHya8A Ask each team: 1. What do engineers do? (Solve problems!) 2. What steps do you think engineers use to solve problems?(Have table groups brainstorm) 3. Present the Engineering Design Process from the Next Generation Science Standards Appendix I Define the Problem Develop Solutions Optimize Solutions What do you notice about the arrows on this poster? (Arrows go both ways) 4. Get ready to read the story: “So, we have a systematic process for solving problems…this is how engineers do their work, but it’s powerful way for you & me to approach problems, too. Figure 1 Engineering Design from NGSS problem do you think the man in this story is going to face?” a What Allow students to share a few ideas, but don’t verify. Read the story; consider using some of the questions during the first reading, especially if you’d like students to predict what’s coming next (and why they think that). Post-Reading 1. Select & use some of the questions listed later in this guide. 2. Use “Another Question” later in this guide, to compare how Fookwire and the squirrels used the 3 components of Engineering Design. 3. Check out the online videos to generate additional thinking and conversation about the problem-solving / design process. 4. Use the Those Darn Squirrels Worksheet to allow students to identify criteria and constraints on p. __ of the book 5. Conduct the Marshmallow Challenge as an extension to the story. See Marshmallow Challenge sheets on p.___ of this guide Literacy Connections 4 (TBA) About Scientific Problem-Solving —Questions to Use with the Story: In the text & pictures… A) Pg.14—Fookwire’s new birdhouse design. [Do you think it will work? Why / why not?] B) Pg.18-19—Fookwire’s third version. [Wow, that’s a complicated system!...What is each part supposed to do? Why do you think this might solve Fookwire’s problem?] C) Pg.20-21—Squirrels engaged in problem-solving. [The squirrels didn’t give up, just like Mr. Fookwire. What parts of the Problem-Solving Process are they using? Do you think their plan will work?] D) Pg.26-27—The squirrels are focusing on a new problem. [What problem do you think the squirrels are working on now?] E) Pg.29—Fookwire at the door. [What do you think Old Man Fookwire sees? Why do you think that?] Another Question: Compare Old Man Fookwire’s problem-solving approach to the squirrels’ problem-solving approach. [Which parts of the process did they both use? What is different about them?] Online Resources Engineering for The Real World (video) What is engineering? http://www.youtube.com/watch?v=bipTWWHya8A (video 2min.)

A. Defining and delimiting engineering problems involves stating the problem to be solved as clearly as possible in terms of criteria for success (goals), and constraints (limits). B. Designing solutions to engineering problems begins with generating a number of different possible solutions, then evaluating potential solutions to see which ones best meet the criteria and constraints of the problem. C. Optimizing the design solution involves a process in which solutions are systematically tested and refined and the final design is improved by trading off less important features for those that are more important. 6 Those Darn Squirrels (Teacher PD) Use the image from the book Those Darn Squirrels to think about Engineering Design Define the problem the squirrels are attempting to solve: Identify constraints (limits): Identify criteria for success (goals): 7 Develop some other solutions than the one pictured above: We know that this solution did not solve the problem. What might the squirrels do to optimize their solution? 8 Birdhouse Images for use in an Optimizing the Solution Task… 9 Marshmallow Challenge Name(s) (Marshmallowchallenge.com) A. Define the Problem Create the tallest free-standing structure using 20 pieces of spaghetti, 1 meter of tape, 1 meter of string, and 1 marshmallow. The marshmallow MUST BE on top of the structure. Constraints: Things that limit your design 20 pieces of dry spaghetti 1 meter of tape 1 meter of string 1 marshmallow 18 minutes Stable structure Free standing As tall as possible Marshmallow mush be on top of structure Criteria: The Goals for your design B. Develop Solutions Explore Ideas (Brainstorming) All Group Members Participate Plan Summary Which idea above did you pick? Write a sentence describing what you will do.

Optimize Solutions Test solutions Make observations and/or measurements to produce data to test a design solution Revise solutions Test two different models of the same proposed object, tool, or process to determine which better meets criteria for success Make a claim about the merit of a solution to a problem by citing relevant evidence about how it meets the criteria and constraints of the problem Can redefine the problem or generate new solutions to replace an idea that just isn’t working out Arrives at an optimal design 17 Those Darn Squirrels by Adam Rubin, Illustrated by Daniel Salmieri Teaching Engineering Design TRAIT Evidence C.
