Lobsters They really do look like big sea bugs. They have a kind of crustacean spring break, in which lady lobsters wait their turn for a brief fling with whichever local male has proven dominant.
We should all be so lucky as to have a partner who brings us food they know we like just because they love us. And it is quite cute—until you learn that the only real goal here is for the male to mate with the female spider before she eats him.
He sometimes just makes a fake present with nothing inside—or worse, wraps the gift, but gets hungry on the way and eats it himself—just so he can have sex. Bowerbirds Enough with the blue already, Damian! Pixabay Male bowerbirds famously build little shrines—called bowers—to entice females to come mate with them. They fill the bowers with shiny things and hop around trying to display their goods as best they can.

Find you a mate who you like as a person, not for their stuff. And stop anthropomorphizing birds. Giraffes You want me to carry a baby for how long??? Pixabay No PopSci animal mating article would be complete without a little giraffe sex. Just something to consider before buying your partner a cute necklace. These birds take ages to reach sexual maturity and even longer to start breeding, allowing for plenty of time to practice their mating dance, which they learn by watching older birds court each other.
Young albatrosses dance with several partners, testing out various pairings, but eventually choose just one partner to dance with forever. They literally have their own special dance that they only do with each other, and then they settle down into a little family for life.

These theories, in turn, can explain bodies of data and predict outcomes of experiments. They are also tools for further development of the subject.
An important component of science is the knowledge of the limitations of current theories, that is, an understanding of those aspects of a theory that are well tested and hence are well established, and of those aspects that are not well tested and hence are provisional and likely to be modified as new empirical evidence is acquired. The process by which scientific theories are developed and the form that those theories take differ from one domain of science to another, but all sciences share certain common features at the core of their problem-solving and inquiry approaches.
Chief among these is the attitude that data and evidence hold a primary position in deciding any issue. Thus, when well-established data, from experiment or observation, conflict with a theory or hypothesis, then that idea must be modified or abandoned and other explanations must be sought that can incorporate or take account of the new evidence. This also means that models, theories, and hypotheses are valued to the extent that they make testable or in principle testable precise predictions for as yet unmeasured or unobserved effects; provide a coherent conceptual framework that is consistent with a body of facts that are currently known; and offer suggestions of new paths for further study.
A process of argumentation and analysis that relates data and theory is another essential feature of science. This includes evaluation of data quality, modeling, and development of new testable questions from the theory, as well as modifying theories as data dictates the need.

Finally, scientists need to be able to examine, review, and evaluate their own knowledge. Holding some parts of a conceptual framework as more or less established and being aware of the ways in which that knowledge may be incomplete are critical scientific practices. The classic scientific method as taught for many years provides only a very general approximation of the actual working of scientists. The process of theory development and testing is iterative, uses both deductive and inductive logic, and incorporates many tools besides direct experiment.
Modeling both mechanical models and computer simulations and scenario building including thought experiments play an important role in the development of scientific knowledge.
Different Perspectives on the Process of Science Those who study the nature of science and the learning of science have a variety of perspectives not only on key elements of scientific practice and skills Stanovich, ; Grandy and Duschl,but also on Page 28 Share Cite Suggested Citation: The committee recognizes that these different perspectives are not mutually exclusive and that, in considering how best to teach science, each can identify certain elements that need to be given their due attention.
We summarize the key elements of a number of these viewpoints. Among psychologists, this view was pioneered by the work of Inhelder and Piaget on formal operations, by the studies of Bruner, Goodnow, and Austin on concept development, and by investigations by Wasonof the type of evidence that people seek when testing their hypotheses.
The image of scientist-as-reasoner continues to be influential in contemporary research Case and Griffin, In this view, learning to think scientifically is a matter of acquiring problem-solving strategies for coordinating theory and evidence Klahr, ; Kuhn,mastering counterfactual reasoning Leslie,distinguishing patterns of evidence that do and do not support a definitive conclusion Amsel and Brock, ; Beck and Robinson, ; Fay and Klahr, ; Vellom and Anderson,and understanding the logic of experimental design Tschirgi, ; Chen and Klahr, These heuristics and skills are considered important targets for research and for education because they are assumed to be widely applicable and to reflect at least some degree of domain generality and transferability Kuhn et al.
Science as a Process of Theory Change This view places emphasis on the parallel between historical and philosophical aspects of science Kuhn, and the domains of cognitive development Carey, ; Koslowski, in which domain-specific knowledge evolves via the gradual elaboration of existing theories through the accretion of new facts and knowledge normal science, according to Kuhnpunctuated, occasionally, by the replacement of one theoretical framework by another.
The science-as-theory perspective places its emphasis less on the mastery of domain-general logic, heuristics, or strategies and more on 1 Page 29 Share Cite Suggested Citation: In this view, at critical junctures, as evidence anomalies build up against the established theory, there can occur wholesale restructurings of the theoretical landscape—a paradigm shift, according to Kuhn Nersessian provides a good example of the semantic changes that occur when motion and force are examined across Aristotelian, Galilean, and Newtonian frameworks.
This view focuses on the nature of scientific activity, both in the short term e. Science as practice suggests that theory development and reasoning are components of a larger ensemble of activity that includes networks of participants and institutions Latour, ; Longino, ; specialized ways of talking and writing Bazerman, ; modeling, using either mechanical and mathematical models or computer-based simulations Nersessian, ; and development of representations that render phenomena accessible, visualizable, and transportable Gooding, ; Latour, ; Lehrer and Schauble, They received the Nobel prize in medicine in for their discovery of the bacterial origins of stomach ulcers.
Untilthe prevailing view was that gastric ulcers were caused by lifestyle and stress. When Marshall and Warren suggested that ulcers were caused by the bacterium Helicobacter pylori, their claim was viewed as preposterous Page 30 Share Cite Suggested Citation: The reasons for both the initial and final positions in the field clearly involve important social mechanisms that go beyond simple evidence-based reasoning processes.
However, to acknowledge the influence of situated, social, and noncognitive factors in the process of scientific discovery is not to deny the existence of an external physical reality that science attempts to discover and explain see, e. Language of Science In science, words often are given very specific meanings that are different from and often more restrictive than their everyday usage.
A few such cases are important to discuss before we proceed further in this report.Rethinking infidelity ... a talk for anyone who has ever loved - Esther Perel
It is also important for teachers to be aware of the confusion that can arise from these multiple usages of familiar words, clarifying the specific scientific usage when needed. Through those tests and the resulting refinement, it takes a form that is a well-established description of, and predictor for, phenomena in a particular domain. A theory is so well established that it is unlikely that new data within that domain will totally discredit it; instead, the theory may be modified and revised to take into account new evidence.
What is the Science term for a give and take relationship
There may be domains in which the theory can be applied but has yet to be tested; in those domains the theory is called a working hypothesis.
Scientists use and test hypotheses in the development and refinement of models and scenarios that collectively serve as tools in the development of a theory.
One alternative use of the term comes from psychological research.
