For example, consider the idea that cells are the building blocks of life. In fact, we do observe this our actual observation , so evidence supports the idea that living things are built from cells. Summing up the process Putting the pieces together: The hard work of building arguments. The core of science page 1 of 5 previous next. The core of science: Relating evidence and ideas.
Testing ideas with evidence from the natural world is at the core of science. Scientific testing involves figuring out what we would expect to observe if an idea were correct and comparing that expectation to what we actually observe.
Scientific arguments are built from an idea and the evidence relevant to that idea. Scientific arguments can be built in any order. Sometimes a scientific idea precedes any evidence relevant to it, and other times the evidence helps inspire the idea.

Climate change is one example. Scientific evidence is information gathered from scientific research, which takes a lot of time and patience!
Research needs money to pay for laboratory equipment, field surveys, and materials - not to mention the wages of all the people involved in the project. The majority of researchers have to constantly apply for funds to carry out their research.
These funds can come from different places, usually government bodies such as the Australian Research Council ARC , academic or research institutions, non-profit organisations or even industry bodies.
Mostly, funds are distributed fairly. This means using proved or appropriate ways of collecting and analysing the data and ensuring the research is conducted ethically and safely. Control scenarios may also be necessary when testing for effects or impacts — such as when developing new products such as medicines , or evaluating management actions such as farmland pesticide use. The control scenario represents the opposite of the scenario being tested. This is so the results that are seen in the test scenario are guaranteed to be from the tested product or impact, and nothing else.
If the scenario involves environmental processes of some kind, the test and control should ideally be carried out under natural conditions or in an environment where these processes normally occur. Take the recent neonicotinoid issue. Animal research can be useful, and can predict effects also seen in humans. However, observed effects can also differ, so subsequent human trials are required before a particular effect can be said to be seen in humans. Tests on isolated cells can also produce different results to those in the body.
A case report is a written record on a particular subject. Though low on the hierarchy of evidence, they can aid detection of new diseases, or side effects of treatments. A case series is similar, but tracks multiple subjects. Both types of study cannot prove causation, only correlation.
