Scientific method and Engineering Design process

Front

What is the Scientific Method?

Back

A systematic process used for scientific investigation, involving observation, hypothesis formation, experimentation, and conclusion.

Front

What is the Engineering Design Process?

Back

A series of steps that engineers follow to come up with a solution to a problem, including defining the problem, brainstorming, designing, building, testing, and improving.

Front

What are qualitative observations?

Back

Observations that describe qualities or characteristics and cannot be expressed in numbers.

Front

What are quantitative observations?

Back

Observations that involve measurements and can be expressed in numbers.

Front

What is an independent variable?

Back

The variable in an experiment that is deliberately changed or manipulated by the scientist.

Front

What is a dependent variable?

Back

The variable in an experiment that is measured or observed to see how it changes in response to the independent variable.

Front

What is a control group?

Back

A group in an experiment that does not receive the treatment and is used as a benchmark to measure how the other tested subjects do.

Front

What is a hypothesis?

Back

A proposed explanation for a phenomenon, which can be tested through experimentation.

Front

What is the purpose of the Engineering Design Process?

Back

To create or improve products and solutions to meet specific needs or solve problems.

Front

What is the first step in the Scientific Method?

Back

Making observations and asking questions about a phenomenon.
