Want this question answered?
Be clear about the purpose of the experiment.
A new question in an experiment would be a revised hypothesis.
no you would have a purple baby
The question would be "Why did the author write this?"
The same answer as your purpose in asking such a dumb question
That would depend on who was asking the question, in what circumstances and for what purpose.
It would help if the question was completed before posting it!
A good experiment with light would be to use different wavelengths and to see which ones the chlorophyll reacts to the most actively.
The difference between a general interest science question and a testable question would be: A general question would be like "Whats your favorite TV show. And a testable question would be like "Will my experiment work or not?
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
Known as the Michelson and Morley experiment, this was an experiment to measure changes in the speed of light. Supposedly, as Earth travelled through the Ether, light would go faster in one direction than in the other (because of the relative velocities). The experiment didn't produce the expected result - the speed of light was found to be always the same. Today, this is an accepted fact - that the speed of light is the same for all observers - and is one of the bases for the Theory of Relativity.
