7. Science constructs laws and theories. A theory explains a phenomenon and
the relationship among natural phenomena. Laws describe the causes and
effects within a specific phenomenon. An example of this can be found in
comprehending the theory of evolution and the laws of motion. The theory
attempts to explain the phenomena, but laws are mathematically calculable
predictions of natural phenomena.
8. Democracy has no place within science. The observations and inferences
made cannot be legitimised by votes. A phenomenon either exists or it does
not. All theories are falsifiable. This means that one single piece of contradictory
evidence can disprove a theory. An explanation that has been disproved will
never be accepted no matter how many people ‘believe’ it is true.

Science is embedded in a socio-cultural milieu (context) that is influenced by
the culture and society in which it is practiced. The values will influence how
science is conducted, interpreted, accepted and used. The ethical and moral
guidelines of society have an influence on research that can be conducted. The
debate around the use of embryos in stem cell research is one such example.
6. Science relies on observation and inference. We
observe phenomena through using the five external
human senses. Inference is the interpretation
(meaning-making process) of these observations.
Having many scientists observing the same phenomenon would lead to multiple
perspectives that enrich the body of knowledge. The ability to reason causally
is essential to making inferences. An inference is a conclusion that is reached
on the basis of evidence and reasoning

3. Creativity and innovation are needed. Logical reasoning, with the assistance
of human creativity, gives rise to scientific knowledge. Creativity can be seen
as our ability to create new knowledge by rearranging the connections of known
elements. In science we often re-evaluate a theory when new evidence is
discovered. By using creativity, we often find new ways to reason about the
existing evidence and then create new possible explanations.
4. Science is subjective: Presently accepted scientific theories and laws
influence and drive the questions, investigations, and interpretations regarding
phenomena in the natural world. Scientists conduct their work based on these
accepted theories. Their own values, agendas and prior experiences have an
influence on their work. It is nearly impossible for a person to remove all of their
biases and, therefore, all scientific work has a small element of subjectivity

1. Science is tentative: The knowledge obtained is subject to change. New
discoveries and observations are often made that challenge the existing and
accepted hypotheses of the time. This leads to reinterpretation and adaption of
the existing hypothesis. In other words, the theories can change if new evidence
is provided that shows a contradictory explanation.
2. Science relies on empirical evidence without which a
hypothesis remains speculative. Evidence is a series
of facts that are deduced from observations that are
interconnected and presented in such a way as to
support the explanation of a natural
