What's the difference between a hypothesis and a theory?
"Theory" is another word for "fact". "Hypothesis" is another word for "guess".
Hypotheses cannot be proven correct; theories can be proven correct.
Theories have been confirmed through doing fair tests, hypotheses have not been confirmed.
Theories contain many hypotheses; an hypothesis contains only one theory.
Place the following steps in the sequence when following the scientific method: A) Recognizing a problem; B) Testing a hypothesis; C) Making inferences
A, B, C
C, B, A
B, A, C
C, A, B
What must you do before you make a hypothesis?
Do an experiment
Make an observation
Form a theory
Make conclusions
If you were running an experiment to determine the temperature at which beans germinate fastest, what would be the independent variable?
The time taken for the bean seeds to germinate.
The number of bean seeds used.
The type of soil you planted the bean seeds in.
The temperature you kept the bean seeds at.
You should run three or more trials of the same experiment to make sure your results are consistent. What does "consistent" mean?

Perfect
Always being about the same
Testable
Which of the following is a testable hypothesis?
Roses are more beautiful than violets.
A plant needs at least 5 hours per day of sunlight to grow.
Ice cream is very nice.
Humans will someday land on Mars.
What should you do if you test a hypothesis multiple times and the data doesn't support your prediction?
Change the data so that it supports your hypothesis.
Keep running the experiment until you get the results you are looking for.
Conclude that your hypothesis cannot be proven correct.
Re-think you hypothesis.
