Green Clean Chemical Company has developed a product that can be used to recycle garbage. In order to test the manufacturing of the product, Green Clean needs to

  1. Build a model of the product
  1. Create a prototype of the product
  1. Build a pilot plant to manufacture some of the product
  1. Perform a series of experiments on the product

#2

You designed and tested a solar stove, and now you are ready to make your prototype. What criteria would best help you evaluate how well your prototype works?

  1. The location of the test
  1. The cost of the prototype
  1. The size of the stove
  1. The time it takes to cook food

As part of a class project, Jamal wants to design a bicycle that will reach speeds of 50 km/h. He will be using new light-weight material for the frame and a new, more powerful system of gears. Over the entire bicycle, he will install an aerodynamic covering. What kind of prototype should he make?

  1. A full-scale model using the new framing material, the new gears, and the cover
  1. An existing bicycle with the new gears and the aerodynamic covering
  1. A half-scale model with less expensive material, gears, and covering
  1. A full-scale model with less expensive material, gears, and covering

#4

What is the purpose of building a prototype?

  1. To test the product and make sure that it is the best solution to the problem
  1. To make sure that the product is in compliance with government regulations
  1. To test the product before large amounts of money are spent building manufacturing facilities for it
  1. To determine the design constraints for the product

#5

What is a prototype?

  1. A half-scale model which will be shown to customers for feedback
  1. A full-scale model upon which future products are based
  1. A full-scale model that will be tested extensively for design flaws
  1. A scaled-down version of real manufacturing facility

About two percent of Earth’s water is stored in solid form such as icebergs and glaciers. Ice reflects a large portion of the Sun’s energy that enters Earth’s atmosphere, keeping Earth’s surface temperature in balance. If the solid forms of water began to melt due to global warming, how might Earth be affected?

  1. The ozone would become depleted, allowing increased amounts of UV radiation to reach Earth’s surface.
  1. The level of CO2 in the atmosphere would increase
  1. Air pollution from factories, power plants, and automobiles would harm sensitive tissues of many organisms
  1. Sea levels would rise across the surface of Earth, which could affect coastal cities

#7

An unintended consequence of transporting oil by ships across oceans is

  1. An increase in oil prices
  1. An oil spill that can harm water birds
  1. Corrosion to large ocean-going ships
  1. Loss of habitat for the American bald eagle

#8

What is a benefit and a consequence of using salt on icy roads?

  1. Salt roughens the surface of roads but turns creeks and lakes salty.
  1. Salt melts snow and ice on roads, but causes nicks and dents in cars.
  1. Salt melts snow and ice on roads, but corrodes cars and bridges.
  1. Salt freezes the surface of roads, but causes potholes.

#9

Which technological innovation caused the brown pelican to disappear from Louisiana and most of Texas in the early 1970s?

  1. A new pesticide
  1. Larger propellers on boats
  1. Increased air traffic near water
  1. A new fertilizer

#10

A battery manufacturing plant is having problems with a robotic arm in the assembly line. The engineers need to design a new arm. Look at the steps below. What belongs in step #4?

  1. Develop a pilot plant.
  1. Create a one-half scale model of the best solution.
  1. Develop a prototype.
  1. Perform experiments on the different solutions.
