  1. Work Sample: Engineering Design Grades 3-5

  2. Engineering Design:Background for the Instructor How do engineers solve problems? • Defining and Delimiting an Engineering Problem • What is the design for? • What are the criteria and constraints of a successful solution? • Developing Possible Solutions • What is the process for developing potential design solutions? • Optimizing the Design Solution • How can the various proposed design solutions be compared and improved? 2

  4. The Engineering CycleHow do engineers solve problems? First of all, help students understand the Engineering Cycle • THINK IT! • First describe the problem or need you want to solve • EXPLORE IT! • Make a list of possible ways to solve the problem • SKETCH IT! • Draw a picture of your idea • CREATE IT! • Build your prototype and be sure to write down each step • TRY IT! • Perform experiments to find out how well your prototype works • TWEAK IT! • How can you improve on your prototype or model? 4

  5. Scoring Domain 1:Identifying and Defining a Problem to Be Solved Based on observations and scientific principles, formulate the statement of a problem or need that can be addressed through the process of engineering design. Scoring Guide: Uses design criteria and constraints to clarify the problem

  6. Identifying and Defining a Problem to be Solved The design constraints and criteria* should reflect the needs of society or the end-user and address such things as: • The product’s or system’s function (students need to identify what job it will perform and how) • Availability or cost of materials (provide students with an example of a Bill of Materials, a budget, and/or a cost analysis sheet) • Aesthetics • Its reliability and durability • Limits on its size * Help students understand the terms - constraints and criteria. A constraint is a limitation or condition that must be satisfied by a design. A criterion is a standard or attribute of a design that can be measured. 4

  7. Students need to be able to…- Explain the problem they need to solve.- Specify how they will solve it. Third Grade Expectations Teacher gives students a problem to be solved, design criteria, and constraints. Note: The problem should be related to the science curriculum previously studied.

  8. Students need to be able to… Fourth and Fifth Grade Expectations • Identify a testable engineering problem that they could solve. • Specify how they will solve it (design criteria and constraints). • Link their problem and solution to prior knowledge, observations, or scientific principles. Note: The problem should be related to the science curriculum previously studied.

  9. Instructional Scaffolds • Discuss current world or community problems that could be solved through engineering (pollution, oil spills, building new bridges, better school designs). • Provide examples of problems that have been solved through engineering (inventions). • Bring in everyday objects and discuss the problems they were designed to solve (hammer, can opener, tape dispenser, stapler) . • Create sentence frames such as “A _____ solved the problem of ____.”

  10. Scoring Domain 2:Generating Possible Solutions Select an engineering solution and evaluate that solution using criteria and constraints. Scoring Guide: • Proposes a testable engineering solution to the identified problem • Evaluates (Communicates – grade 3) the proposed solution in terms of design criteria and constraints

  11. Components of Effective Possible Engineering Solutions • More than one possible solution • Evaluate the proposed solution to see if it would work • Evaluate constraints of problems. i.e. “What is important? What is not?” • Justifies a solution for testing.

  12. Scaffolding:Generating Possible Solutions • Review real life engineering problems and solutions: Failed inventions, oil spills, and historical events • Provide current research examples of problems and solutions • Start with whole class activity (Gradual Release) • Provide models and modeling

  13. Understand cause and effect Materials Prototype Defined Sequencing Solution needs to directly relate to the problem Understand how to evaluate- evaluate a solution Have to perform a solution that is testable Define testable Solution connects to the problem Sentence Frame/Graphic Organizer How to use and list available materials Examples of a prototype “working model” Act it out, arrange a sequence, graphic organizer Speech to verbally justify solution Rubric, science checklist, defend their solution Guidelines for design Instruction - Scaffolding

  14. Scoring Domain 3:Testing Solutions and Collecting Data: Test solution by collecting, organizing, and displaying data to facilitate the analysis of test results. Scoring Guide: Designs and builds a prototype that addresses the problem and can be tested with appropriate tools, materials, and resources. Records the results from testing the solution. Presents the results in a format that facilitates analysis (Uses a teacher provided data table - grade 3)

  15. Scaffolds Create a student friendly checklist that students need to follow Use the Gradual Release of Responsibility model for instruction Provide sentence frames to support students development of ideas

  16. Scoring Domain 4:Analyzing and Interpreting Results Select an engineering solution and evaluate that solution using criteria and constraints. Scoring Guide: Proposes an engineering solution to the identified problem Evaluates the proposed solution in terms of design criteria and constraints

  17. Steps for Analyzing and Interpreting Results • Summarize the results • Was the problem solved? • Can the problem be solved? - without being too expensive? - without hurting people or the environment? - by matching its appearance to its intended purpose? • List possible problems created by the design • What happens if the design doesn’t work?

  18. Scaffolding Skills and Sentence Frames Summarizing • The problem began when __________. • The ___________ tried to __________. • After that, ________________. • Then, __________________ • The problem was finally resolved when __________________. Cause and Effect • If ____ is ____, then ____. • One possible outcome of ____ might be ____. • Because ____ is ____, the result will be ____. Making Judgments • I think ________ are ____________. • I think that ________ is important to ________ because __________. • In my opinion ___________decided to __________.
