Question

engineering design process
match the step to the real - life example.

1. identify the problem
2. brainstorm/research
3. choose the best solution
4. design
5. build
6. test and evaluate
7. re - designing
8. re - build
9. re - test and re - evaluate
10. share solution/conclusion

a. he decided to first try diluted vinegar.
b. instead of using the store - bought products, he decided to try some other household products that he had around his house. he looked through his cabinets and came up with a number of ideas for products that he could try using.
c. after applying that to the stove top and scrubbing for a little bit, the grease was removed.
d. he ended up writing an email to all of his friends about what had worked in case they were having the same problem themselves.
e. he mixed the 2 tablespoons of baking soda with a tablespoon of water in a small dish.
f. the cleaners that reid bought from the store just never seemed to clean the grease on his stove very well.
g. he took a spray bottle and filled it up halfway with vinegar and the other half with water.
h. after that he decided to try making a paste of water and baking soda.
i. he sprayed the stove top, dried it off and determined that it still did not take off the grease as well as he wanted.
j. with the materials he had available, he decided a spray bottle would be best to use for the mixture.

Explanation:

1. The problem of store - bought cleaners not cleaning stove grease well is identified in F.
2. Looking through cabinets for alternative household products is brainstorming/research in B.
3. Deciding a spray bottle is best for the mixture is choosing the best solution in J.
4. Mixing baking soda and water is part of the design in E.
5. Filling a spray bottle with vinegar and water is building in G.
6. Spraying and checking if the grease is removed is testing and evaluating in I.
7. Deciding to try making a paste after the first attempt is re - designing in H.
8. No clear re - build example.
9. No clear second re - test and re - evaluate example.
10. Telling friends about what worked is sharing the solution in D.

Answer:

1. F
2. B
3. J
4. E
5. G
6. I
7. H
8. None
9. None
10. D
