The board is lighter, thinner, and smoother, and the wheel attachment is less bulky.

Open Ended

How does the last skateboard differ from the previous two?

The board is lighter, thinner, and smoother, and the wheel attachment is less bulky.

​The board now has a curved-up

​edge; the wheels are different.

​The shape and material of the board

​has changed.

The board is lighter, thinner, and smoother, and the wheel attachment is less bulky.

The shape of the board and the

​footpads make it more comfortable

​and easier for the skater to grip.

​The material is less bulky and more

​responsive.

Imagine a normal bicycle. Now think of ways it could be modified to work better in different environments.​

Open Ended

​The engineers at an appliance company have developed a new dishwasher. It looks very different from previous models. The controls look different and work differently. The part of the machine that heats the water has been completely redesigned. Now that the plans are completed, should the company start producing thousands of these dishwashers? Why or why not?​

​No; They need to build and test prototypes first. They need to see if people like the new look. They need to find out if the controls are easy to use. They need to make sure the controls and the water heater work the way they are supposed to work.
