Systematic observation by nature is structured. Unlike unstructured observation, systematic observation includes recording the phenomenon of interest (i.e. behavior) across different settings and over a significant period of time. The results from such an activity leads to the gathering of meaningful data. This in essence means that the observer can interpret the data to explain and reveal specific patterns of behaviors. Researchers always form hypothesis before entering the field to record events or behaviors, so it is of paramount importance for observers to use a theoretical model to help guide the interpretation of the recorded behaviors or events. Unstructured random observation, in contrast, does not allow anyone to make meaningful interpretations or find meaningful patterns of behaviors.
As for experiments, they are the most important tool that scientists use to produce new knowledge. Experiments involve the manipulation of variables (anything that can take different values). Perhaps the most important feature of experiments is the presence of a control group used for comparison reasons against the experimental group. The control group and the experimental group are identical in every respect, but differ only on the independent variable which is of course the variable the experimenter manipulates. This way, any recorded differences between the two groups could be attributed to the independent variable and not some other confounding variable. Through experiments, researcher can identify causal relations, that is, what causes what. This is the only method that could be used to determine causation in most scientific disciplines.

An explanation from observations and experiments?
thesis
Repeating observations or experiments to confirm prior conclusions?
replication
Information obtained from experiments observations or measurements is called what?
data.
What is the name for a generalization base on many observations and experiments?
scientific method
What is science and what science is not?
Science is the systematic, reasoned study of the physical world through observation and experiment. Efforts to explain the world that presuppose an answer are outside the realm of science, as are explanations that disregard contradictory observations and experiments. oh yea it is.

How is the validity of scientic theory tested?
Scientific Theory is tested by observations and experiments predicted by the theory. If the observations confirm the theory the theory is validated if not the theory is not validated. Experiments themselves need validation, often there are errors in the experiments or observations, e.g Michaelson and Morley Aether experiment and red shift observations.
What did galileos observations confirm?
He made many experiments and observations in the field of physics in general.
What can be made in the field or in the labortatory?
observations...i think Observations and Experiments can be made in lab and field.
What is an explanation based on a observations from repeated experiments?
It is a theory.
Explanation based on observations from repeated experiments?
theory
What is the difference between controlled and uncontrolled observations?
controlled experiments are conducted in the laboratory environment whereas uncontrolled experiments observations data collected over a period of time
Why so important that the scientist must be logical and systematic?
if they are not they could mess up their experiments and make the it useless. science is all about the facts. why does this happen, when does this happen, and what effects it.
Did controlled experiments or multiple observations lead to the generalization that all organisms are composed of cells?
controlled experiments!
How did Louis Pasteur make observations and collect results?
he did experiments

What do most astronauts do in space?
do observations, try experiments and more
