The factor that is deliberately changed or manipulated is

• A theory

• The dependent variable

• The data

• The independent variable

Scientific models are

• Representations of objects or processes that are not easily observable

• Fashion models who are also scientists

• Testable ideas or explanations that lead to scientific invstigation

• Dependent upon the dependent variable

If a scientist's hypothesis is not supported by the data they collect, the scientist should

• fix the hypothesis to match the data

• fix the data to match the hypothesis

• form a new hypothesis and experiment

• repeat the experiment 10 more times

A scientific theory may change because

• the public doesn't like it

• new evidence is found

• an important scientist says it isn't true

• theories never change

The correct sequence of steps in the scientific method are

• collect data, analyze data, draw conclusions

• plan an experiment, analyze results, form a hypothesis

• draw conclusions, plan an experiment, collect data

• perform an experiment, ask a question, collect data

Graphs are important because

• they show data in a visual way

• they prove the results of an experiment

• they make the data more interesting

• they really are not important

In an experiment testing the effect of different colored lights on plant growth, the dependent variable is

• the colors of the lights

• the type of plant used

• the amount of light the plants receive

• the amount of growth of the plants

A control group

• is used to measure the results found in the experimental group

• is not important and can be skipped

• is the only group that has the independent variable

• the group that shows the results of the independent variable

Observations that deal with a number or amount are called

• qualitative

• quantitative

• inferences

• evidence

Using one or more of your senses to gather information is called

• Inferring

• Observing

• Predicting

• Hypothesizing
