Designing Like an Engineer!

1. Designing Like an Engineer! http://www.cartoonaday.com/rube-goldberg-machine-cartoon/

2. Engineer Design Challenge #1 Using the materials provided, work as a team to create something that will solve a problem within the classroom. One box of spaghetti and one cup of mini marshmallows.

3. Vocabulary Engineer: Someone who uses his or her creativity and knowledge of math and science to design technologies that solve problems. Green engineer: An engineer who works to lessen environmental impacts of all kinds of engineering projects. Technology: Anything designed by people to help solve a problem or meet a need. Insulation: A material that slows the movement of energy. R-value: The measure of the heat resistance of a material.

4. Ask - Define the problem. • Imagine - Brainstorm. • Plan - Design. • Create - Build. • Improve - Test, Evaluate, Redesign. • Present - Share solution. Engineering Design Process Simple Descriptions

5. Communication The Four C’s Collaboration Creativity/Innovation Critical Thinking

6. Scientific Method and Engineer Design Process Scientific Method (TESTING A HYPOTHESIS) Ask a question => => => Hypothesis => => Lab Procedure => => Test the Hypothesis, Analyze the results => Draw conclusions => => Communicate results => => Engineer Design Process(TRYING TO SOLVE A PROBLEM) Ask Imagine Plan Create Improve Present

7. Reflection Think back to the initial challenge, using the marshmallows and spaghetti. Which steps of the EDP did you use? What steps could you have included to make the challenge more successful? Give at least one example of how your group used any of the four C’s.

8. ASK What is the problem? How have others approached it? What are your constraints? ASK: This is the problem that needs a solution.

9. Create a model for an energy efficient home built out of a shipping container. ASK

10. Criteria and Constraints are used throughout the design process to determine which of many possible designs should be implemented. • Criteria: rules or directions that must be followed; they are the requirements that must be met. • Constraint: a limitation or condition that must be satisfied by a design. What are criteria and constraints?

11. Examples of Criteria and Constraints Criteria: What your solution needs to do. The end result. The answer to the question which is the ask step of the EDP. This is what you need to accomplish. Constraints: Ways you are limited Amount of time given to complete a task. Materials that you are limited to using. Methods that you can use or not use.

12. What do you need to know to create a solution? Criteria Create a model of a Container home with the most effective insulation against heat. Constraints • Temperature will be measured at the beginning and 5 minutes later. • Can only use the included materials. • Stay within a budget of $1000

15. IMAGINE What are some solutions? Brainstorm ideas. Choose the best one. IMAGINE: This is the time to let your mind come up with as many ways you can create the insulation for your container home. Make sure you are following your criteria and constraints.

16. Time to Design: Complete the “Imagine” Section of your paper Criteria Create a model of a Container home with the most effective insulation against heat. • Constraints • Temperature will be measured at the beginning and 5 minutes later. • Can only use the included materials. • Stay within a budget of $1000 • Materials • Sun lamp • L-Bracket • Thermometer • Poster board • Box Template • Aluminum Foil • Foam Sheets • Felt Sheets • Construction Paper • Bubble Wrap • Cotton ball bag (6 per bag) • Transparency Sheets • Sand bag (½ cup per bag)

17. PLAN Draw a diagram. Make lists of the materials you will need. Label your diagram. PLAN: In your group, have each member explain their best solution for their container home. Work together to combine the best elements of each design for the plan.

18. Time to Design: As a team complete the “PlAN” Section of your paper Criteria Create a model of a Container home with the most effective insulation against heat. • Constraints • Temperature will be measured at the beginning and 5 minutes later. • Can only use the included materials. • Stay within a budget of $1000 • Once you have a plan get your plan approved and start building! • Materials: • Sun lamp • L-Bracket • Thermometer • Poster board • Box Template • Aluminum Foil • Foam Sheets • Felt Sheets • Construction Paper • Bubble Wrap • Cotton ball bag (6 per bag) • Transparency Sheets • Sand bag (½ cup per bag)

19. CREATE Follow your plan and create something. Test it out! CREATE: Use your plan to implement your solution - well insulated model container home. Stick to your plan and make only minor changes.

20. IMPROVE What works? What doesn’t? What could work better? Modify your designs to make it better. Test it out! IMPROVE: Did your plan do what it was supposed to do? Make changes that make it work, work better or any improvements that would add value to the project.

21. Present Share the original design, improvements and final product. PRESENT: Go through the steps that you took to come up with the solution that you have. Include the beginning steps of the EDP and the improvements that were needed.
