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

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
