A prediction is a statement about what may happen in the future. A prediction will be deduced from a hypothesis. For example, we can predict that if you leave a plant in a cupboard with no water or light. It will die. A prediction and a hypothesis are slightly different. The hypothesis of tis same example would be that all plants need water and light to survive.

For example, Theory A states that all woolly mammoths are extinct. Theory B states that there are still woolly mammoths alive today. Theory A is a scientific theory, because it could be disproved if a woolly mammoth was found. Theory B is unscientific because it can never be proved that there are no woolly mammoths anywhere.

The usual test for a statement of fact is verifiable —that is, whether it can be demonstrated to correspond to experience. Standard reference works are often used to check facts.

"a thing that is accepted as true or as certain to happen, without proof."
- Part of the hypothesis phase
In natural sciences assumptions are necessary
Science operates on the assumptions that:
-  There are natural causes for things that happen in the world around us.
- Evidence from the natural world can be used to learn about those causes.
- There is consistency in the causes that operate in the natural world.
These assumptions are important, they form much of the basis for how we interact with the world and each other everyday.

"a regular and intelligible form or sequence discernible in the way in which something happens or is done." 
-general patterns give us knowledge 
-Math is a good example because if an answer keeps recurring then that shows that it works is evidence for it being the right answer.

Anastasija

Convention is an agreement that we make in order to allow certain social activities to take place smoothly.  There are many conventions observed in the natural sciences in order that science can take place as a shared social activity. One of examples is the units that we use like metre second, kilogram and standard units. This means that scientists who work in different parts of the world can work together, because they have the same understanding of how we should measure various aspects.  Without convention we would not have standard ways of comparing and communicating the science that we do all around the world. 

This is an issue, because not all conventions are true and not everybody agrees on a particular convention. For example, biological organisms have an official scientific name. Scientific names come in two parts , the first part the genus and the second part the species. The genus names is always capitalized, and the species name is never capitalized (even if it is a proper noun!). The genus and species names are always italicized or underlined. Recent changes in the nomenclatural code also requires family names to be italicized, but this practice is not universally adopted.

It means that some of the measurements we take or the results we receive may not be accurate, since observing may have affected the thing being measured. 

For example, to "see" an electron, a photon must first interact with it. This interaction will change the path of that electron, therefore changing what is being measured.

Sense perception is the empirical way of knowing- it is more about physical knowledge (how to knowledge). It relates to the five traditional senses; hearing, sight, taste, touch and smell. As well as this there are theoretical senses (such as a sense of movement, a sense of hunger) which is debated about. 

An example is listening to music, or watching a movie. These senses are the basis of 'how to knowledge'

It is one way that a theory can be incorrectly 'proven', based on judgement and interpretation of results.

An example would be someone who believes that the earth is flat seeing that the earth looks flat from where they are standing, and taking that as evidence that the earth is flat, while disregarding evidence otherwise.]]> 2016-10-14 10:41:23 UTC https://padlet.com/b_bouwman/5yxznh62d89f/wish/130689208 Theory Ladenness https://padlet.com/b_bouwman/5yxznh62d89f/wish/131150627 Theory ladenness is]]> 2016-10-17 14:16:05 UTC https://padlet.com/b_bouwman/5yxznh62d89f/wish/131150627 Models and Prediction https://padlet.com/b_bouwman/5yxznh62d89f/wish/132120543 Daryll Netscher
Models and Predictions are a controversial topic within the natural sciences for their various effects on our theories and such. What is meant by this is that their are countless amounts of factors that affect the outcome of our experiment and therefore we cannot rely on one model to predict and/or confirm our answer. This leads us to the issue of proving theories correct as well because if we do not know whether the model is correct, then how do we know that an answer is correct. Therefore a theory remains correct until proven wrong. ]]> 2016-10-20 15:50:55 UTC https://padlet.com/b_bouwman/5yxznh62d89f/wish/132120543 1420341 https://padlet.com/b_bouwman/5yxznh62d89f/wish/132544012 Chady, Agniv&Daryll]]> 2016-10-23 14:49:27 UTC https://padlet.com/b_bouwman/5yxznh62d89f/wish/132544012 Observer effect - Jeanine jeanineros https://padlet.com/b_bouwman/5yxznh62d89f/wish/132634144 2016-10-24 09:30:23 UTC https://padlet.com/b_bouwman/5yxznh62d89f/wish/132634144 Convention https://padlet.com/b_bouwman/5yxznh62d89f/wish/134054109 Eminovic
