The ecologist could then test the hypothesis and prediction by carefully recording numbers of birds and their insect prey over several spring seasons.

If you observe closely you will notice air is flowing into the first hole allowing the pressure inside of the bottle to increase and water to flow out of the second hole. Then, based on predictions made from the hypotheses, we will describe the information we need to decide which belief is true that is, if the predictions are accurate.Some of the worksheets displayed are Hypothesis work 2 name underline the iv what is the, Work on hypothesis tests, Name writing a hypothesis work remember to step 1, Hypothesis practice, Writing a hypothesis, Variables hypothesis work, Hypothesis generation work, Research question and hypothesis work.
