1.) The controlled scientific experiment carried out in the Hubbard Brook Experimental Forest
2.) Science is an effort to explain how the physical world works by making observations and measurements, and carrying out experiments. It is based on the assumption that events in the physical world follow orderly cause-and-effect patterns that we can understand.
Carrying out experiments involves the scientific process. The first step in the scientific process is identifying the problem. There must be a problem worth studying in order for the scientific process to be needed. The second step is to find out what is known about the problem in order to conduct a correct and relevant experiment. The third step is to develop a question for the experiment to be based off of.

A model is an approximate representation or simulation of a system.
A scientific hypothesis is a possible explanation of what scientists observe in nature or in the results of their experiment. A scientific theory is a well-tested and widely accepted scientific hypothesis. The Scientific Law (Law of Nature) is a statement based on repeated experimental observations that describes some aspect of the universe.
Peer review involves scientists openly publishing details of the models and methods they used, the results of their experiments, and the reasoning behind their hypothesis for other scientists in their field (their peers) to evaluate. Its important because scientific knowledge advances in this way, with scientists continually questioning the measurements and data produced by their peers.
Scientific theories are not to be taken lightly because they are tested widely, supported by extensive evidence, and are accepted as being useful explanations used by most scientists. The term “theory” is often used incorrectly because they do not understand how rigorously scientific theories are tested before they become widely
