The Nature of Technology: Design and Systems
Grades 6-8, page 51
All technologies have effects other than those intended by the design,
some of which may have been predictable and some not. In either case, these
side effects may turn out to be unacceptable to some of the population
and therefore lead to conflict between groups.

Evaluate completed technological designs or products. Students should
use criteria relevant to the original purpose or need, consider a variety
of factors that might affect acceptability and suitability for intended
users or beneficiaries, and develop measures of quality with respect to
such criteria and factors; they should also suggest improvements and, for
their own products, try proposed modifications.

Scientific inquiry and technological design have similarities and differences.
Scientists propose explanations for questions about the natural world,
and engineers propose solutions relating to human problems, needs, and
aspirations. Technological solutions are temporary; technologies exist
within nature and so they cannot contravene physical or biological principles;
technological solutions have side effects; and technologies cost, carry
risks, and provide benefits.

Technological solutions have intended benefits and unintended consequences.
Some consequences can be predicted, others cannot.

Evaluate the solution and its consequences. Students should test any
solution against the needs and criteria it was designed to meet. At this
stage, new criteria not originally considered may be reviewed.
