APPLICATIONScience, Technology, and Society
Transfer and apply abilities in science and technological design to develop solutions to societal issues
Application
• Technological Design Process
• Criteria for Success
Fact First Questioning
Application Scenario Guidelines
Application scenarios describe a technological design process students use to solve a problem. The problem must be one that involves a
Life Science System*
• Write out the steps of a technological design process.
Glossary DefinitionTechnological design process: A
sequence of steps used to define and solve a problem. The steps may include: defining the problem in terms of criteria and constraints, gathering information about the problem through research, generating ideas for possible solutions, synthesizing or selecting of one or more promising ideas or solutions, constructing a plan or model to test the proposed idea or solution, redesigning if needed and communicating the results
