 Science NetLinks: Spontaneous Generation
Because of these experiences, students should already know that results of similar investigations are seldom the same, and that this could be due to differences in the things being investigated, in the method being used, or the circumstances under which the experiments are carried out.
In middle school, students should come to understand that scientific knowledge is stable (meaning that there is a core body of knowledge that's stable) and always subject to modification (due to research that slowly corrects and extends the boundaries of science).
Experiments and observations often have a hypothesis, or an idea that comes first, even if the idea is that the current thought may be wrong.

Because the knowledge, research, and equipment needed to develop biological agents into weapons were initially scarce or expensive, during the first half of the century the use of biological warfare was generally practiced only at the state-sponsored level.
Scientifically advanced biological weapons development: The advancement of scientific knowledge about infectious agents and disease vectors, as well as the wide availability of requisite equipment, meant that biological agents could be developed using relatively inexpensive means and with potentially devastating effects.
Historical incidents of biological warfare or biological agent use with the intent of causing harm in the 20th century are roughly grouped on the timeline.

The History of Science and Technology is a field of history which examines the entire spectrum of human experience relating to science and technology, including the development of theories, change between theories, disciplinary and institutional history, and the cultural, economic, and political impacts of science and technology.
In the shadow of the first war to employ chemical weapons, and as the war machines were again gearing up in preparation for another world war, the role between science, technology, and warfare was becoming more interesting to scholars and scientists.
Internalist histories of science often focus on the rational reconstruction of scientific theories and showing the development of science as being a process taking place wholly within the scientific world.

According to accepted scientific dogma, the discovery of the viroid was not supposed to happen.
The scientific dogma in 1971 was that an organism with no protein wasn't supposed to be able to replicate itself, even with a host cell's help.
Diener spent the next 5 years isolating and characterizing the viroid, verifying his experiments, filling in the holes, preparing to meet the skepticism that generally greets proposals of new, “impossible” concepts.

 [No title]
It is a poor example, however, because within a few years Galileo was one of the most honored scientists in Italy, and held in high regard by the Jesuit astronomers of the Collegium Romanum—who were using telescopes with enthusiasm.
They claim that theories developed and tested by following the currently accepted principles of scientific investigation closely, as Galileo did, are generally accepted however surprising they may be, whereas ideas that make yet unproven and seemingly unjustified assumptions are termed pseudoscience.
The first report, which received extremely intense press coverage, caused many physicists to attempt to reproduce the experiment (a necessary process in science); these first attempts resulted in many complete failures, at least three widely reported claims of success that were later withdrawn, and no clear and reproducible successes.

Serious droughts and other unusual weather since 1972 increase scientific and public concern about climate change, with cooling from aerosols suspected to be as likely as warming; journalists talk of ice age.
Scientific opinion tends to converge on global warming, not cooling, as the chief climate risk in next century.
This is a reference list of miscellaneous significant developments that don't fit into any of the other essays: scientific-technical matters that arose altogether independently of the scientific fields covered, and are not included above in the list of major "milestones," but that did have a significant influence on climate change studies.
