This is the step of the Design Process that comes between "Plan and Build" and "Redesign?"
What is "Test and Improve?"
Early communication of sending letters was affected by this.
What is transportation?
(using horses, stagecoaches, and later trains)
Engineers use this with their knowledge of math and science in order to solve practical problems.
What is engineering?
Which two models are the best in durability?
Models A and B
This is one criterion that should be included in the design of a prosthetic knee.
Sample answer:
It should bend like a natural knee so he/she can walk easily.
These are the standards that help engineers determine how well a design is doing its job.
What is criteria?
Any device or item that people use to meet a need or solve a problem is this.
What is technology?
This is another tool that scientists use that is similar to a prototype.
What is a model?
What criteria are being tested according to this data table?
"Range of remote opener" and "time for the door to open"
A wheelchair ramp is not an example of a prosthetic because it does not replace one of these.
What is a body part?
An engineering team needs this in order to test a new design.
What is a prototype?
Washing machines, door knobs, and cell phones are examples of this.
What is technology?
This is set to determine whether the design achieves the purpose.
What is the criteria?
Engineers who have recorded data about different cars' miles driven per gallon could communicate their results by making one of these.
What is a bar graph comparing miles per gallon?
Crutches are an example of biotechnology because they are a product used to benefit these.
What are living things?
This is step 4 of the design process.
What is Redesign?
Technology has many risks and benefits. This is a physical risk of using a cell phone and driving.
What is distracted driving?
Two friends want to make a better scratching post for their cat. What are two questions they should ask themselves before they begin designing one?
Sample answers:
How tall it should be
What materials they should use
Later, the engineers discover that "Model B" doesn't clean the dishes well, so what should they do next?
Evaluate what is wrong with model B and work to REDESIGN it. (Step 4 of the Design Process)
Pumping blood to the lungs and body is something that bio-engineers will want this to be able to do.
What is an artificial heart?
This process can best be described by explaining that it uses math and science to solve practical problems.
What is the Design Process?
When communicating results, you should include conclusions you have drawn and take notes about the ___________ of your design and whether the criteria was met.
What is a prototype?
Engineers need to test fabric for a ship's sail. Stressing the fabric with wind and weather over time could help engineers determine this.
What are the design flaws of the fabric for the sail
Each letter stands for a model of a dishwasher. They wanted to develop a more efficient dishwasher that used less water in less time. Which model met their criteria best?
Model B
An of example of this is a walker because it assists a damaged body part.
What is a prosthetic?
