What is science?

• Science is the study of the natural world ( vs engineering which is about solving human needs)

• Science aims to explain and understand

The knowledge that is built by science is always open to question and revision. No scientific idea is ever once-and-for-all "proved." Why not? Well, science is constantly seeking new evidence, which could reveal problems with our current understandings. Ideas that we fully accept today may be rejected or modified in light of new evidence discovered tomorrow

• Science works with testable ideas

Only testable ideas are within the purview of science. For an idea to be testable, it must logically generate specific expectations — in other words, a set of observations that we could expect to make if the idea were true and a set of observations that would be inconsistent with the idea and lead you to believe that it is not true.

• Science relies on evidence

• Science is embedded in the scientific community

• Scientific ideas lead to ongoing research
