Weegy: hy how may i help you? User: describe how scientists and biologists study the world Weegy: By means of the scientific method. First we observe the behavior of the universe. We observe that plants grow at different speeds. [ We observe that some objects in the sky stay still relative to each other while others seem to move around. Then we imagine what physical processes might explain that behavior. We imagine that some factor of a plant's environment might affect its growth. We imagine that some objects in the sky might be very far away, while others might be very close. We select some of those postulated processes that seem the most likely and try to devise a way to test those hypotheses. We suspect that water is an environmental factor that affects plant growth, so we get two plants and water them differently, hoping to attribute any difference in growth to that difference. We suspect that motion of allegedly nearby objects might correspond to a simple Newtonian formula and so see whether the formula, if solved for a future point in time, predicts the location of the object. Then we operate those experiments to see whether what we expect to happen, based on the prediction of our hypothesis of cause-and-effect, actually happens. If it doesn't, then we reject that hypothesis and try another one. If it does, we consider that to be the prevalent theory until we make observations that don't fit it. Then we extend or refine the hypothesis to account for those new observations and repeat the testing and verification process. We keep doing this essentially forever. Our ability to make better and better observations as time passes helps us refine the correctness of our understanding of physical law. ] (More)
