Engineering Design Process Steps

DEFINE: What is the problem? Who are you solving for?

Based on the video and images you saw, what problem(s) are these areas facing?

Summarize Article:

With your group, create a chart of the parts, people, and interactions in the article.

Parts	People	Interactions
Island of Maiana Seawater Freshwater Soil Salt Fruit crops	Teraiman Rubo	Freshwater interacts with seawater and makes soil dry. Salt dissolved in freshwater kills fruit crops. Seawater + Freshwater = Dead crops

EXAMPLE

Choose a User:

Engineers design solutions with a user in mind.

With your group discuss:

Who’s problem would you like to solve?
Why are you interested in solving that person’s problem?
What are the parts and interactions related to that user?

Topic: Defining Problems

Answer the reflection questions below:

What problem(s) did you observe in today’s lesson?
What do you think might have caused the problem(s)?
Why do you think it is important for engineers to define a problem and choose a user before they come up with a solution?
Who do did you choose as your user? Why did you want to solve their problem?
Do you know of any other users who might be facing similar problems? Explain
