Write scientific reports; an assigned topic will be researched and presented in scientific format. The (cid:862) (cid:272)ie(cid:374)tifi(cid:272) method(cid:863) is the idea that e(cid:448)e(cid:396)yo(cid:374)e sta(cid:396)ts (cid:271)y (cid:373)aki(cid:374)g observations and then subconsciously makes a hypothesis. Over time they will test the hypothesis and suggest whether it is correct or not. Eventually a theory is developed but testing never stops. If all the tests are passed, we can make predictions for an end result. One that is always successful is reworded into a law.
