Science Coordinator ESD112 APPLICATIONWork with other members of a team to apply the full process of technological design and relevant science concepts to solving a problem.

Science, Technology, and Problem Solving

Application

• Technological Design Process

• Problem Solving

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 physical,

Earth/space, or living 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

Problem: Lift a heavy stump out of a hole.

Explore Ideas: Use a long lever to lift the heavy stump. Pull the stump up a ramp. Lift the stump with a pulley. Get more people and all lift the stump at once.

Using some or all of the materials shown, describe how you would design a way of lifting an even heavier stump.
