Implementing proposed solutions. Children should develop abilities
to work individually and collaboratively and to use suitable tools, techniques,
and quantitative measurements when appropriate. Students should demonstrate
the ability to balance simple constraints in problem solving.

People have always had problems and invented tools and techniques (ways
of doing something) to solve problems. Trying to determine the effects
of solutions helps people avoid some new problems.

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.
