1. During which step of an investigation would
a scientist publish a report in a scientific
journal?
A. develop and use a model
B. communicate information
C. analyze and interpret data
D. use data to design a solution
2. For which purpose is a life-cycle analysis of
a resource most effective?
A. to decide how to best obtain a resource
B. to decide whether a resource is useful to
humans
C. to analyze the features of a resource
compared with other resources
D. to figure out the total cost of producing,
using, and disposing of a resource
3. Which of these would be a constraint of a
design problem?
A. The design should be lightweight.
B. The design should be easy to open.
C. The design should be under 1 meter in
length.
D. The design should be environmentally
friendly.
4. Bill conducts an experiment in which she
changes the release height of a steel ball and
measures the distance the ball travels from
the ramp before falling to the ground. The
diagram shows Bill's experiment.
ramp
steel ball
release height
path of ball
location where ball
strikes the floor
distance
Based on this procedure, which question is
Bill investigating?
A. How much force does the ball exert when it
strikes the floor?
B. How is the speed of the ball affected by the
release height from a ramp?
C. How does the release height of a ball on a
ramp affect the amount of time that passes
before the ball hits the floor?
D. How does the release height of a ball on a
ramp affect the distance the ball travels
from the ramp before falling to the floor?
5. Why would an engineer choose to use
repeated testing during the design process?
A. to improve the quality and usefulness of a
design
B. to try very different ways to solve a design
problem
C. to reduce the amount of time it takes to
develop a design
D. to make sure that the first solution to the
design problem is the best one
