∙ 11y agoIn the scientific community, knowledge is not considered static. Our understanding of how life works changes with new knowledge. Hypothesies are ideas about how something works (to be a true scientific hypothesis, it must be able to both be proven and disproven) and almost always change rapidly with new experimental data. A theory is a hypothesis that is well-proven, backed by very many different experiments. A law is a theory that has been in effect for a looong time, and still holds up to evidence. So, as new scientific evidence comes into human knowledge which counteracts a given law, theory, or hypothesis, scientists rethink and go back to more experiments. They'll examine the perameters and room for errors (example: prior to the 2012 phenomenon, particles were found to go faster than the previously-veiwed fastest speed available, the speed of light, but the evidence was disregarded due to large margin for errors granted by machinery). Hypothesies are always changing, but theories and laws rarely are disproved, and, when they are, MUCH effort goes into making sure everything is legitimate

Can models be used to collect data and make predictions?
when models chave been validated with evidence
When do scientific models need to be changed?
Scientific models are continually refined through experimentation. When experimental results, which violate the model, have been confirmed by a third-party then scientists seeks to change the model such that the results can be explained.
What could be used by a student to better understand scientific principles and concepts?
Physical evidence, mathematical models, and computation tools
Why was the scientific model developed?
Well if we didn't have any models and so we would not have any models
What is the difference between history and science?
Science investigates models of natural law using repeatable experiments as the ultimate arbiter. In contrast, history investigates past events by considering physical evidence, documentary evidence, and eyewitness testimony.
Can models be changed after they are created?
Yes, they certainly can. Modification of intellectual models in the light of new evidence is one of the cornerstones of the scientific process.
When can models be used to collect data and make predictions?
when models chave been validated with evidence
How do scientist study evidence for the formation of rodinia?
They use computer models to show how this new evidence supports formation of a supercontinent long before Pangea.
Explain why diffusion is evidence for particle models?
Diffusion is evidence for particle models because it causes diffusions
How does a scientific theory change?
Scientist are always testing their models to get new information or results, but other times learning evidence makes scientist have to change their models so scientist can change their models in theory.
When can models be used to collect and make predictions?
when models chave been validated with evidence

What is the main criterion by which scientist judge the usefulness of a model?
The usefulness of a model is based on the models ability to explain a set of facts. In light of new evidence and new facts within the models reported domain, if it can continue to explain these new facts, its robustness lends even more to its 'usefulness'.
Are jaguars affected in global warming?
There is no evidence that shows jaguars are being affected by climate change.
Can a zygote be affected by chlamydia when fertilized?
There's no evidence that the zygote is affected by chlamydia at the time of fertilization.
Where can one hire models from new faces?
You can hire Models from New Faces directly from the New Faces Website. You can also look for Models online from New Faces from the official Models Website.
How do you prove perjury in West Virginia?
The same as you do anywhere else. You must present evidence or proof that refutes the perjured item, or testimony. If the perjury affected the outcome of a judicial action, you will have to file a motion to re-open the case based on new evidence.
