Document Summary
~observation- act of viewing the world around us. ~experimentation- disciplined and controlled way of asking and answering questions about the world in an unbiased manner. ~variable- put into a test group to see if there is an effect. ~control- does not include the variable, expected no change in group. ~scientific method- deliberate and careful way of asking questions of the unknown. ~theory- general explanation of the world supported by a large body of experiments and observations. ~living organisms: complexity, with precise spatial organization on several levels, but still subject to basic laws of chemistry, the ability to change in response to the environment, the ability to reproduce, the capacity to evolve. ~universe as a whole contains oxygen and silicon with aluminum, iron, a(cid:374)d (cid:272)al(cid:272)iu(cid:373), i(cid:374) earth s (cid:272)rust there is o(cid:454)(cid:455)ge(cid:374), (cid:272)ar(cid:271)o(cid:374), a(cid:374)d h(cid:455)droge(cid:374).
