Why might a scientist repeat an experiment if she did not make a mistake in the first one?
Scientists who repeat experiments make the most money
It helps ensure the results are consistent and repeatable.
Repeating ensures the expected results match the hypothesis.
It helps find portions that can be skipped with the same results.
Which question is NOT scientifically testable allowing a conclusion to be made based on scientific evidence?
Does water boils at 100°C?
Are cats are quicker than mice?
Is swimming more fun than skating?
Does salt has a higher melting point than sugar?
What is scientific investigation?
a graph created based on data
a question posed to a question
the results to a formal procedure
a journey to find answers to a question
A scientist is making observations. She is watching a variety of cat species. She is looking to see how cats benefit from their use of camouflage. Which would NOT support a scientist's observations about camouflage?
a puma hunting at night
a black housecat hiding under the bed
a lion sunbathing during the day in the desert
a white bengal tiger running through the Siberian tundra
Scientist A believes she has discovered a new procedure that is better than a procedure currently in use by physicians. She tests her procedure on several occasions and achieves excellent results. Her procedure could be accepted as the best when a community of scientists
accept Scientist A’s procedure automatically because of her credentials.
carry on further discussion, using many trials if experimentation is needed.
carry on further discussion, using only a few trials if experimentation is needed.
reject Scientist A’s procedure; once a procedure is put into place, it can’t be altered with new evidence.
When is evidence really scientific?
After trying to change what has already proven to be correct
When it can be repeated
After proving yourself by a hypothesis.
After you try it and get a different response
Reaching a conclusion based on evidence and reasoning
This is a wrong answer
Explanations that are based on opinion rather than evidence are not scientific.
You should always associate the dependent variable with
What format do you structure a hypothesis
My hpothesis is...
The hypothesis I created...
If and then..
