How science works
Scientific observations can be made directly with our own senses or may be made indirectly through the use of tools.
See Science Shorts
Scientists test their ideas (hypotheses and theories) by figuring out what expectations are generated by an idea and making observations to find out whether those expectations are borne out.
All scientific tests involve making assumptions, but these assumptions can be independently tested, increasing our confidence in our test results.
