Defining Science Science: Systematic knowledge of the physical or natural world gained through observation and experimentation. Focuses on how and why things happen. Scientists answer questions.

Defining Technology Technology: Application of knowledge to solve practical problems or to change/manipulate the human environment. Focuses on making things happen. Engineers solve problems.

The Scientific Method The Scientific Method is a linear method for conducting an investigation that involves making an observation and performing an experiment to test a hypothesis. Make an Observation Propose a Hypothesis Design an Experiment Test the Hypothesis Accept or Reject the Hypothesis Revise the Hypothesis or Draw Conclusions Technology: Application of knowledge to solve practical problems or to change/manipulate the human environment. Focuses on making things happen. Engineers solve problems.

The Engineering Design Process The Engineering Design Process is a systematic, iterative problem- solving method that produces solutions to meet human needs and wants. Systematically applies mathematics and science to produce tangible products that meet human needs or wants.

The Engineering Design Process (12 Steps) Step 1. Define Problem Step 2. Brainstorm Possible Solutions Step 3. Research Ideas/Explore Possibilities Step 4. Specify Constraints and Identify Criteria Step 5. Consider Alternative Solutions Step 6. Select and Approach Step 7. Develop a Written Design Proposal Step 8. Make a Model/Prototype Step 9. Test and Evaluate Step 10. Refine and Improve Step 11. Create/Make Product Step 12. Communicate Results
