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
ConclusionsTechnology:
• 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

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
