What type of science describes natural structures and processes as accurately as possible through careful observation and analysis of data?

• observational (discovery science)

• scientific method

What other method of "doing science" is a series of steps to collect information or solve problems - it involves observation, hypothesis, experimentation, data analysis and conclusion?

• observational (discovery science)

• scientific method

Students in a science class placed ice cubes in a cup. They were studying variables that affected how long it takes the ice to melt. Select the variable that would most likely NOT affect the time it takes the ice to melt.

• Number of students

• Temperature of the room

• Size of ice cube

• Size of cup

What is the correct order of the steps in the scientific method.

• Ask a question, analyze results, make a hypothesis, test the hypothesis, draw conclusions, communicate results.

An experiment that tests only one factor at a time by using a comparison of a control group and an experimental group is?

• a dependent variable

• an independent variable

• a theory

• a controlled experiment

In an experiment, the one variable that is changed is called the

• dependent variable

• controlled variable

• experimental variable

• independent variable

In an experiment, the factor that we measure is called the

• conclusion

• independent variable

• dependent variable

• controlled variable

A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is?

• the incubator

• the male alligators

• the gender of the alligator

• the temperature
