The Engineering Design Process is central to engineering.   I think it is important to stress and guide the process. 

 I found that making  the comparison to cooking was a good connection for the process. A new recipe for cookies is good story line. 

Define:  "Create a new kind of cookie?  
Research:  think about your favorite cookies, talk to people, cookbooks, on-line research.  Look at ingrediants and details of portions and cooking temperatures.  
Brainstorm:   What kind of cookie do we want to create?  Ingredients, tools, equipment needed?   Based on our research, what proportions, temperature, size of individual cookies. 
Build:  Develop a recipe 
Test:  Make the cookies
Prototype:  Your first cookie results
Communicate:  Taste the results!   Too soft, hard, flat, burnt, raw?   What was good, what needed improvement?  Share that info.
Redesign:  Modify and refine your recipe which leads back to Define the Problem.  Why didn't our cookies rise?

Criteria:   Taste, texture, size, perhaps cost
Constraints:  Budget,  size of oven,  allergies


Suggestion
 A lot of time kids want to jump into building without much thought or planning.  This often leads to a lot of wasted time and material wasted and sometimes frustration leading to a "giving up" attitude.     When teaching in a classroom I tried to develop guided hands-on activities which helped develop some basic understanding principles like center of gravity,  friction, air resistance, especially if it would be cumbersome or difficult to research the topic.
