Why is it important to use the scientific method to investigate a claim?

To test and see if the claim is actually true

EDP

100

What does EDP stand for?

Engineering design process 

200

Is the design process ever final?

no- it is a continuous cycle

300

What are the steps in the engineering design process 

1. Identify the problem

2. Brainstorm 

3. Design 

4. Build 

5. Test and evaluate 

6. If successful; share solution. If not- redesign, rebuild, retest 

400

Criteria or constraints?

- Needs to be 100 ft tall with an observation deck

Understand the problem needing to be solved

200

A prototype should be constructed

•  A. In order to test a model of the design solution
•  B. With model proportions that are the exact same size as they are in real life
•  C. Using precise details and color
•  D. Answers A. and B.

A & B
