1. Warm Up #7
Think about a simple object, like a can opener, eyeglasses, a pen, scissors, a spoon, etc.
What is something you wish the object would do or would do better?

2. Technology and the Design Process
Lesson 3: The Design Process

3. Essential Questions What is the design process?
How can different solutions be tested and compared?

4. Creativity and Design Factors
Creativity – the ability to make new things or to think of new ideas
Plays a large role in designing products
Engineering, appearance, cost, and efficiency are other factors
Efficiency – the ability to achieve a desired result with as little effort and waste as possible
Why is creativity an important design factor?
How can creativity affect the design of a product?

5. Creativity and Design Factors
Creativity leads to original and imaginative ideas that can help solve a problem or meet a need, while others can’t
Engineering turns an idea into a product that works well, is durable, reliable, and easy to maintain
Appearance is important to the purchaser
Everyone has slightly different ideas about why is attractive, which is why products often come in different designs

6. Designing Products
Why can old ideas be improved?

7. Designing Products Why can old ideas be improved?
Old ideas can be improved because advancements have been made in science and technology
Design process – a series of steps used to find solutions to specific problems

8. Improving on Old Ideas ACTIVITY
Discuss how this product was used
How did this product benefit society at the time?
What are some problems in this design?
What are some things that were done to improve on this product?

9. Designing Products Identifying a problem or a need
Clearly define the problem, which must be specific enough that a solution is possible
Problem statement – a statement that clearly defines a problem to be solved
Poorly worded statements result in wasted time and effort
Criteria and constraints
Criteria – the standards by which the product will be evaluated
Constraints – limitations put on the design of the product from outside factors, such as cost, efficiency, environmental impact, or availability of materials

10. Designing Products Research information and develop solutions
Researching solutions that have been tried, failed, and worked is a great starting point as it could save you time and get you a better solution
Brainstorming – a problem-solving technique that involves individuals contributing ideas without the fear of being criticized
Pugh charts
Used when people need to pick between multiple objects
Pugh chart – a method used to compare options or solutions

11. Warm Up #8
Why is a prototype important?

12. Pugh Chart Activity Compare and Contrast the 2 items with each other.
Put your criteria into a pugh chart
What was some of your criteria?

13. Designing Products Construct a prototype
Prototype – a full-scale model that is used to test a new product
The prototype is tested and changes are made based on tests
Testing and evaluating solutions
The design is tested and reviewed throughout process
Allows engineer to find and correct problems
Redesigning your solution
Does the product work the way it should?
Does it meet the criteria and constraints?

14. Designing Products Communicate results Full-scale production
Results must be communicated no matter what
Reports are made, presentations are had
Full-scale production
Once all problems are resolved, the new product is manufactured
During this process careful evaluation and testing occur with everything

15. The Design Process Why is it important to test a solution?
What happens in the design process if a new solution is proposed?
Why is communicating results an essential part of the design process?
Why is it important to continue the evaluation process after full-scale production begins?

16. Review
Copy and fill in the graphic organizer to list the steps in the design process.
Solve the problem of a river flooding annually by putting the following steps in order:
Investigating the river’s source and its geography
Build a model dam
Create several designs of dames
Write a problem statement
Test the model
Select the most promising dam design
Redesign the model
