Hypothesis on finding if the dissappearance of a particular fish species from a lake in the northwestern united states is due to acid rain resulting from industrial air pollution
What do you think? Is the disappearance due to acid rain -- or not?
I would say maybe, it could be due to the water temperature, against other lakes should betested as well. What would you say. I would also test against other lakes that have acid rain via non acid rain lakes as well.
It sounds like your hypothesis is:
The disappearance of XXXX species of fish from YYYY Lake is due to acid rain.
sientists do their experimental tests more than once, so they can reduce the effects of chance errors.This is called conducting?
