answers
A __________ model may involve a formula that describes the passing of
mechanical waves through materials. Ans✓✓✓-mathematical
A group of scientists studies the nature of earthquakes by passing mechanical
waves through various materials in a lab. Which type of model are the scientists
are using? Ans✓✓✓-Physical
A physical model Ans✓✓✓-explains current observations and predicts new ones.
computer model Ans✓✓✓-more detailed and complex models
conceptual model Ans✓✓✓-used to visualize things that cannot be seen such as
atoms.
control variable Ans✓✓✓-The variable that scientists do not wish to study that
needs to either be eliminated or kept constant
controlled experiment Ans✓✓✓-a scientist intentionally changes one quantity
and observes how another quantity changes.
dependent variable Ans✓✓✓-The outcome factor; the variable that may change
in response to manipulations of the independent variable.
