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

making a hypothesis
interpreting data
making observations

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
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 dependent variable is?
the size of the baby alligators
the incubator
the gender of the baby alligators
the temperature
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the independent variable is?
the number of plants in the water
the temperature of the water
the amount of salt in the water
the water
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the dependent variable is?
the number of plants in the water
the temperature of the water
the amount of salt in the water
the water
In science, an educated guess is called a/an
observation
question
hypothesis
conclusion
When you decide whether or not the data supports the original hypothesis, you are
forming a hypothesis
asking questions
making observations
drawing conclusions
When a scientist shares her findings with other scientists, she is
making a hypothesis
communicating results
experimenting
analyzing data
In which step of the scientific method do we want to use graphs
communicate results
make a hypothesis
analyze data
asking questions
The final part; a summary of reasonable inferences is a/an
conclusion
controlled experiment
hypothesis
