Discuss why experimental results must be reproducible in order to be considered valid?
If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.
Who must draw conclusions based on the results obtained from an experiment?
Intelligent investigators.
When an experiment is repeated and the new results are different from the original results what may likely be inferred?
The first must be inaccurate because you are sure the second results are correct.
What are the basic principles of scientific approach?
Science proceeds via experiments, and the basic principal of the experiment is that the results of any experiment must be able to be reproduced in any laboratory, any where in the World, at any time (under constant conditions known as STP - standard temperature and pressure).
Why must at least two successive mass readings be equal before finishing the experiment?
In order for experiment results to be trusted, they must be both precise and accurate. Successive instrument readings help guarantee both of these.
How is a control useful in a scientific experiment?
A control experiment provides a benchmark against which to compare the results of the main experiment. For example, to know if heating a material changes its resistance, you must be able to compare the results of the heated experiment to a copy in which the material was left unheated.
What is the results of an experiment must be?
reproducible!
Why do experiment need to be repeated?
Your experiment must be able to be repeated so you can conduct multiple trials, thus eliminating errors. It must also be able to be replicated so other scientists can repeat it themselves.
What must a hypothesis have to be considered scientific?
To make your hypothesis considered scientific it must have testable and measurable results. Example: If you do an experiment and the results are testable and measurable another person would be able to do the exact same project and come out with the same results.

What must a spices be able to do in order to survive and reproduce?
A species must be able to find food, shelter, and water in order to survive and reproduce. Until a species is able to meet its essential needs, it is not able to reproduce and survive.
To be a valid scientific experiment the results must be?
Repeatable
Why do scientist use control groups in experiments?
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.

If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.
Who must draw conclusions based on the results obtained from an experiment?
Intelligent investigators.
Is it true that an experiment must follow sound scientific principles for its results to be interpreted?
no
What does a valid experiment must include?
a control group and statistical analysys of the resultsalso, to be considered valid, the results of a scientific experiment must be repeatable and still proven correct.
