What methods are used in the study of natural sciences?

Methodology –

Science is a way of thinking more than it is a body of knowledge. Carl Sagan When you cannot measure, your knowledge is meagre and unsatisfactory. Lord Kelvin

Scientists try to “map” the natural world. This map tries to describe, predict and explain different essential aspects of the natural world. To produce knowledge about the natural world, scientists currently use a particular method: the scientific method,

This method is based on observation and hypothesis, which is tested (through experimentation). Scientists may formulate a law and/or a theory, both of which explain things about the natural world. A scientific law “predicts the results of certain initial conditions” (Matt Anticole at TEDed). In short, it predicts and explains what will happen.

A scientific theory, on the other hand, “provides the most logical explanation as to why things happen as they do”. In short, it explains why things happen. Sometimes scientific laws stand the test of time, whereas theories don’t. Kepler’s laws of planetary motions, for example, are still used today, whereas his theory of musical harmony has now been replaced with the theory of gravity to explain why the planets move the way they do ( see TED ed, theory versus law ).

  • To verify the reliability of your hypothesis, you (and others) should ideally be able to repeat your experiments.
  • Repeating experimentation may help us accept that something is right.
  • In theory, this seems feasible within the natural sciences, because the natural world can arguably be verified empirically.

However, some great scientific hypotheses cannot be tested through experiments based on observable data. Our sense perception is not perfect, and despite the enormous advancements in technology, we cannot observe as much as we would like to. It is also practically impossible to repeat experiments infinitely.

In that sense, Popper proposed that scientists try to falsify (prove wrong) each others’ ideas and findings. For example, if a scientist claims that metals expand when heated, other scientists are invited to actively prove that this is not true. They could look for situations in which metals do not expand when heated.

This process of falsification aims to ensure the validity of scientific knowledge. It may also lead to the improvement of scientific knowledge, as theories can be refined, for example. Nevertheless, the processes of falsification as well as verification are limited.

This is partly due to problems with induction, reasoning and observation, which all play an important role within the scientific method. Reason and observation (through sense perception) are very much key to the scientific method. We use inductive reasoning to come up with a hypothesis. We observe things around us and pick up patterns.

From these patterns we may form a hypothesis that explains what happens or even why things happen. We need reason to do this. We can evaluate the validity of scientific knowledge by verifying whether the rules of mathematics and reason have been respected.

  1. We can also verify whether findings are empirically correct.
  2. But sometimes empirical data contradicts a theory and vice versa.
  3. In a way, it is very difficult to offer ultimate proof of scientific knowledge.
  4. This is especially the case if we want to create knowledge about things that cannot easily be observed.

Sometimes we have to observe the effects of something rather than the thing we want to observe, sometimes the tools we use to observe (such as is the case of fMRIs) are quite far removed from a simple act of observing. Extensions such as telescopes and magnifying glasses are arguably mere extensions.

  • But there is more at hand with fMRIs.
  • In addition, sometimes observing is not as passive as what may appears to be the case.
  • If we were to stick with what was easily observed and verified, our scientific knowledge would be limited.
  • In addition, by relying merely on reason and sense perception, we may well be able to explain what happens, but we would probably be less successful at explaining why this happen.

Revolutionary breakthroughs in the natural sciences show that scientists sometimes had to take “a leap of faith”. On occasion, observable evidence was not available yet, In that sense, the leap of faith relates to going beyond available evidence. For example, 100 years after Einstein predicted their existence, we now have evidence of gravitational waves.

  1. Sometimes scientists have to overcome the limits of our current frame of understanding things.
  2. They have to look at things from a different perspective and offer a more original theory than the ones that fit within the worldview at the time.
  3. In this context, it is worth remembering that imagination plays a much bigger role within the scientific method than may appear at first sight.

Helen de Cruz and Johan de Smedt argue that (progress in) science is in fact a form of structured imagination, whereby analogies with knowledge in other fields drive scientific discoveries. In fact, our intuitions about the natural world are often not very scientific at all.

For example, children across the world intuitively feel that earth is flat. If no one told you that the earth travelled around the sun, your intuition would probably tell you it was the other way around. By transferring distant analogies, we can overcome these intuitions and make scientific progress through what de Cruz and de Smedt call ‘structured imagination’.

By using good reasoning skills combined with imagination, great thinkers such as Copernicus made important breakthroughs in the natural sciences. Re​flection: Can we still call a discipline a natural science if we take away its scientific method?

Is the natural world studied in science?

Science asks questions about the natural world. – Science studies the natural world, This includes the components of the physical universe around us like atoms, plants, ecosystems, people, societies and galaxies, as well as the natural forces at work on those things. Anything in the natural world — from exotic ecosystems to urban smog — can be the subject of scientific inquiry. Photo credits: Flickr user Christian Collins and Flickr user Jay Peeples, Science can investigate all sorts of questions:

When did the oldest rocks on earth form? Through what chemical reactions do fungi get energy from the nutrients they absorb? What causes Jupiter’s red spot? How does smog move through the atmosphere?

Very few questions are off-limits in science, but the sorts of answers science can provide are limited. Science can only answer in terms of natural phenomena and natural processes. When we ask ourselves questions like “What is the meaning of life?” and “Does the soul exist?” we generally expect answers that are outside of the natural world — and hence, outside of science.

Why do we study the natural world?

The benefits of study – The value of field study is vast: field experiences not only contribute to better science, but also create better scientists, citizens, and people, thereby substantially affecting the human-nature relationships that form the basis for sustainability.

  • Observing nature is the touchstone for understanding how life works, and thus field studies serve quite literally as the grounding for the biological sciences.
  • At the same time, field experiences often force observers to question and to re-evaluate their assumptions about how the natural world operates.

Accordingly, field observations can lead to re-calibration of research strategies for exploring biological phenomena, explanations for which are often subsequently tested using information collected by observational approaches in the field. Field observations reveal patterns, and these often lead to the development of formal hypotheses.

  1. Theoretical models are only as solid as the field natural history foundations on which they rest.
  2. Field-based education is particularly critical to the biological sciences, providing fundamental training for key disciplines such as behaviour, ecology, evolution, systematics, and conservation science.

Field studies underlie the conceptual and technical bases for these disciplines and are required to ensure their healthy growth. Now, as society struggles to respond appropriately to losses of biodiversity, range shifts due to climate change, and emergence of new human pathogens, the decline in opportunities for field study means that subsequent generations of biologists will be increasingly divorced from the primary setting – the natural environment – in which the phenomena that they study occur.

As the capacity to modify biological systems expands – from genomes to ecosystems to global cycles – it is imperative that scientists and the broader public can critically evaluate the outcomes of these changes in the context of complex natural settings. Within academia, this need also applies to the educators charged with training future generations of problem solvers.

Field studies are an essential component of every scientist’s training. Field education also promotes the development of place-based understanding. Students who engage in field experiences have greater opportunity to cultivate the critical connections to real places that transform abstract concepts into tangible realities.

  1. This outcome extends to the cultural, social, and political settings in which field studies occur.
  2. A sense of place can be a powerful motivator for learning and stewardship and thus individuals who become strongly connected to a specific setting, tend to become more effective advocates for all elements of that environment.

On an individual level, field studies often spark a “sense of wonder” that can launch students on a path of discovery-based science, resulting in a life-long commitment to careers in natural, environmental, and medical science. Field experiences – in particular, residential and other immersive experiences – also provide unparalleled opportunities for development of intra- and inter-personal skills that are critical to effective leadership.
