Understanding Engineering and Scientific Principles

Front

What is the role of engineers?

Back

Engineers design, build, and maintain machines, structures, and communities.

Front

What is the engineering design process?

Back

A structured process used by engineers to create solutions to problems, starting with identifying a problem or need.

Front

What is the first step in the engineering design process?

Back

Asking questions to clarify what needs to be addressed.

Front

What are constraints in engineering?

Back

Limitations such as time, materials, or budget that engineers must consider.

Front

Why are clear procedures important in scientific inquiry?

Back

They ensure that experiments can be replicated and similar results can be achieved, forming accurate conclusions based on evidence.

Front

What is an independent variable in an experiment?

Back

The variable that the experimenter changes, such as the type of music played to a baby.

Front

What is a dependent variable in an experiment?

Back

The variable that is measured, like the time it takes for a baby to fall asleep.

Front

What is the scientific method?

Back

A method involving formulating a hypothesis and testing it through experimentation, similar to the engineering design process.

Front

What is the importance of brainstorming in the engineering design process?

Back

It is essential for generating possible solutions during the imagine step, encouraging creativity.

Front

What is a series circuit?

Back

A circuit where all devices must be 'on' for electricity to flow.
