Engineering LessonsQuarter 3
Do Now: In your engineering Journal remember to RTQ and put in the date. Use the back of the paper.◦What different things can we measure?◦Do you think measurement is difficult or
easy? Explain.◦Why is it important to have a standard
unit of measurement?

Do Now: ◦ In your Engineering Journal
What do engineers do? Engineers make improvements to products to make
them better Why are engineers important?
Engineers make our lives easier. Have you ever had a problem with something you
bought and thought of a way to change it to make it better? Explain.

Objective Agenda
Understand the design process.
Do Now Notes on The
Engineering Design Process
Practice with the Engineering Design Process
Reflection
During the engineering design process you will jump around between steps and not always work in order. This is called iteration.
Engineering Design Process
Ask questions about the problem you observe◦What is the problem or need?◦Who has the problem or need?◦Why is it important to solve?
Who needs what because of why?
1. Define the Problem
Learn from others and research users and customers or existing solutions.
2. Do Background Research
Find the requirements you must follow for your product ◦How much time do you have?◦What size must it be?◦Are there any extra things you need to
make sure you add?
3. Specify Requierments
Try to think of as many solutions to your problem that you can, no matter how outrageous they may be.
4. Brainstorm Solutions
Look at all of your solutions and pick the solution that best fits your design requirements.
5. Choose the Best Solution
Keep improving the solution. This will continue through the design process.
6. Develop the Solution
This is a model of the final product but is not as polished.
7. Build a Prototype
Test your product and make changes
This will continue through the design process
This is the most important step.
8. Test and Redesign
Communicate your results to others so that others can repeat what you did.
9. Communicate the Results

You work for the Beats company. Many people have been writing to you complaining that their Beats head phones have not been working because of the cold weather. ◦ Define the problem ◦ Brainstorm Solutions ◦ Pick a solution ◦ Sketch a prototype
Think about this:
Do Now: ◦ In your Engineering Journal
What do you think it means when Mrs. Burke says you will be graded on “Lab Skills”?
What are some important Lab skills you would need to remember in the classroom?
What are some important skills you need to use while you are working with a group of people?
