In a controlled experiment, there is only one factor that can change at a time. This tested factor that might affect the outcome of the experiment is called this.
What is the independent variable?
100
These six steps are found in the scientific method.
What are observation, problem, hypothesis, experiment, results, and conclusion?
100
The step of the scientific method during which the scientist notices something that makes her want to conduct an experiment.
What is the observation?
100
The curve of a liquid in a graduated cylinder. You read the bottom of this curve to measure the liquid's volume.
What is the meniscus?
100
The axis that represents the independent variable and runs left to right on the bottom of a graph
What is the x axis?
200
A second factor measured by scientists in an experiment, this factor results from changes to the independent variable.
What is the dependent variable?
200
This is the step of the scientific method where the biology students see alligators living in the creek across from the school.
What is the observation?
200
The step of the scientific method during which the scientist revisits her hypothesis and says whether it was right or wrong and why.
What is the conclusion?
200
This is the SI unit for mass.
What is a gram?
200
This is the variable that the y axis represents.
What is the dependent variable?
300
This is the group in an experiment exposed to the factor being tested.
What is the experimental group?
300
This is the step of the scientific method where the Biology students bring the alligators into the classroom and continue to monitor alligators in the creek. Both groups are given the same food and water.
What is the experiment?
300
The alligators' location/habitat is an example this component of an experiment. (Go back to our alligator experiment example where we wondered if bringing alligators into the classroom would make them die sooner...Think about what those 5 components of an experiment are...)
What is the independent variable?
300
A unit of measurement that is used by scientists all around the world so that they can communicate their experiments and results with each other and so they can repeat experiments
What is an SI Unit?
300
This is the graph you would use when the order of your information on the x axis does matter and when you are graphing something to do with time.
What is line graph?
400
In an experiment, this group is used for comparison.
What is the control group?
400
This is the step of the scientific method where the students determine on average that the alligators in the classroom died 5 years earlier than the alligators in the creek.
What are the results?
400
The number of days or years that the alligator survived is this type of component of an experiment. (Go back to our alligator experiment example where we wondered if bringing alligators into the classroom made them die earlier. Think about our 5 components of an experiment...)
What is the dependent variable?
400
This is the lab equipment used to swirl and mix liquids
What is an erlenmeyer flask
400
These are the three things that every graph needs.
What is a title, axis, and range?
500
In an experiment, this is a factor that remains constant or fixed between the control and experimental group while the independent and dependent variables change.
What is the controlled variable?
500
This is the group that the alligators in the creek belong to.
What is the control group?
500
The alligators who are in the classroom are an example of this component of an experiment. (Go back to our alligator experiment example where we wondered if bringing alligators into the classroom would make them die sooner. Think about the 5 components of an experiment...)
What is the experimental group?
500
The SI unit used to measure volume of a liquid
What is liter?
500
This is the graph you would use if you were graphing the types of sports that people liked most.
