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
