Use of the technological/engineering method should be based on the understanding that this method is concerned with the phenomenon of the human-designed world and with obtaining artifacts and solutions to problems. The phases include

identifying the need or opportunity for an engineering solution
defining a design problem
identifying the constraints of a design problem
researching potential solutions to a design problem
generating multiple solutions (brainstorming) to a design problem
sketching solutions for a design problem
evaluating potential solutions to a design problem
choosing the optimal solution to a design problem
implementing the solutions to the design problem
testing the solution
evaluating the test results
improving the initial solution
communicating the solution to stakeholders.

Science practices include

identifying a problem
researching
forming a hypothesis
planning an experiment
performing an experiment
analyzing data
forming a conclusion
communicating results.
