Scale the following object by a factor of 2/3: Length = 6cm Width = 9cm
What is 4cm (length) by 6cm (width)?

Name the step described in the following scenario: John runs a series of speed and collision tests on the car he is designing. He collects data and makes observations so that he can improve his original design.
What is Test and Evaluate?
200
At which point in the design process do you need to consider the constraints and criteria of your project?
What is test and evaluate?

Scale the following object by a factor of 6.5: Length = 5cm Width = 8cm
What is 32.5cm (length) by 52cm (width)?
300
Name the steps depicted by the following scenarios: A. Suzy creates a poster for her science project that shows her hypothesis, materials, procedure, data, and conclusion. She presents her poster at the science fair. B. Barbara notices that the soles of shoes ware out really fast, but thinks that they should last longer. C. Zach runs a series of tests on his plane prototype to see how well it can fly.
What is A: Communicate the Results B: Identify the Problem C: Test and Evaluate
300
What do we call limitations and guidelines of engineering projects?
What are constraints (limitations) and criteria (guidelines)?

Scale the following object up by a factor of 3.5 AND down by a factor of 3/5: Length = 6.25cm Width = 4.75cm
What is: 21.88cm(length) by 16.63cm(width) AND 3.75cm(length) by 2.85cm(width)

Put the following steps of the scenario in order: A. Bob and his friends build the new lock. B. Based on their tests, they decide that they should put a rubber tube around the outside of the chain to make the chain more durable in different climates, so they build a new model of their chain and lock. C. Bob gets together with a few other people to think of how they can prevent bike thefts. They think of creating a bike alarm system, creating thicker chains with locks on them, and using combination locks instead of locks with keys. D. Bob and his friends present their idea for a new bike lock at the town meeting. E. To see how well the new lock works, Bob and his friends try cutting through the chain with different tools, and they write down their observations. F. Many bikes have been stolen in the neighborhood because the bike locks are easily broken. G. They decide to create a bike lock with a thicker chain and a combination lock.
What is F, C, G, A, E, B, D?

This step is not always a part of the design process.
What is re-design?

Scale a triangle with the following dimensions by a scale factor of 7/8: Side 1 = 9cm Side 2 = 7cm Side 3 = 5cm
What is 7.88cm(side 1) by 6.13cm(side 2) by 4.38cm(side 3)?
