A certain plant is tested to see if it can grow with different types of fertilizer. What is the independent variable?
The different types of fertilizer.
What is the dependent variable in the above sample?
Whether the plant grows or not.
What is the controlled variable in the above sample?
The certain type of plant.
What is the experiment group in the above example?
The certain types of plants being tested with the fertilizer.
What is a hypothesis?
A prediction before an experiment.
Give an example of a hypothesis.
Plant A will grow larger than Plant B because Plant A will be getting more of the same sunlight, water, and fertilizer than plant B.
What’s the difference between independent and dependent variables?
Independent variable don’t rely on something to change and a dependent variable does.
What’s the difference between a control group and an experiment group?
A control group is the original thing. It’s the thing not being experimented on, but it’s being compared while the experiment group is being tested on AND compared.
