Scientific Experimentation Review

Constants

Factors that don’t change in an experiment

Variables

Independent + dependent (x,y)

Independent (manipulated) variable

“manipulated variable”- deliberately changed in an experiment done by you.

Dependent (responding) variable

Responding variable- changes as the result of independent.

Control

Remain constant (don’t change and are used to compare) and allows us to measure change.

Quantitative data

Numerical

Qualitative data

Descriptive

What are some important aspects of a formal hypothesis?

A formal hypothesis should be detailed with your own personal educated guess on the outcome/testable.

Why do scientists repeat experiments?

Scientists repeat experiments to set it as accurate as possible.

Why do scientists use controls in their experiments?

Scientists use controls in their experiments to help them measure the change in their data.

Why do scientists use constants in their experiments?

Scientists use constants to make sure the experiment is fair.
