Each pot will receive a different type of soil, but will get the same type of seed, water amount, and sunlight amount.What is the Independent Variable in this story?
Amount of sunlight
How tall the plant will grow
Amount of water
Type of material the plant is growing in
What do you measure for results (outcome)?
Dependent variable
Hypothesis
Experimental Group
Constants

Why do many experiments include several trials instead of a single trial?
Repetition of trials increases the accuracy of the results
Repetition of trials decreases the sample size of the experiment.
Repetition of trials makes data easier to analyze.
It is not necessary to repeat trials
Quantitative data can be
seen
measured
manipulated
heard
How is a hypothesis different from a theory?
A theory has evidence to back it up and a hypothesis is an educated guess as to what is going to happen.
They are both the same. They both are guesses as to what happens in the natural world.
A theory is an opinion about how something works but a hypothesis has scientific evidence to support it.
A hypothesis is used in science and a theory is used in society.

Which of the following statements about a controlled experiment is true?
All variables must be kept the same.
You should only test one variable at a time.
Controlled experiments must be completed within a lab.
The whole purpose of experiments is to prove your hypothesis was right. We collect data to support our hypothesis.
