The dependent variable is the variable that

is measured during the experiment.

Replication of experiments is necessary because

the more "like" results obtained, the more valid they are.

an attempt to answer a question or problem.

attempts to explain something that you observed.

Why do scientists construct models?

To study something too big, small or complex.

can be qualitative or quantitative.

It depends on the number of trials .
Yes, that is the standard for comparison.

attempts to explain something that you observed.
attempts to explain what may happen in the future.
9
Why do scientists construct models?
To find the independent variable.
To study something too big, small or complex.
Because they can't afford the real thing.
Because scientists like to build models.

Observations
can be dangerous so you always have to wear safety glasses.
