1. Designing Like an Engineer!

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.
The spaghetti and the marshmallows are just a suggestion. Any simple STEM challenge will work. We are giving them minimal information, so that they will see the usefulness of the Engineer Design Process. (EDP) The idea behind solving a problem in the classroom is so they can come up with different solutions to the challenge. Some might find a way to “contain” pencils, others might find a way to support something… It just has to be an opportunity to design something without the process.

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

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
This is the link to the downloadable unit from Engineering is Elementary: Start filling out the EDP template with this slide.

10. What are criteria and constraints?
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.
The Set up for the testing apparatus is here:

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
Possible materials are listed on Page 23 of the Engineering is Elementary Unit: Here Comes the Sun. You can adjust this list to the materials that you have available to you. The following can be used in your constraints: Come to a consensus on the following questions in order to help standardize the experimental procedure: • How far should the sun lamp be from the insulation? We recommend about 5 inches. • How long should insulation be under the sun lamp? We recommend about 6-10 minutes. • How thick should the layer of insulation be? We recommend 1/8 of an inch. • How often should we take temperature readings? We recommend every 1-2 minutes. • Should we have a control? If so, how would we set it up and gather data on it? Yes, it should be the same as the other insulation tests, but with no insulation. Just the thermometer under the sun lamp.

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.
. Tell youths that their challenge will be to explore insulation for a new type of home being built by people all over the world: shipping container homes. Ask: • Has anyone heard of shipping container homes? What do you know about them? It is fine if youths have not heard of shipping container homes. They may know shipping containers are used to transport goods on cargo ships. People have started re-purposing old shipping containers as homes.

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
