Document Summary
The scientific method (for increasing the body of scientific knowledge; a systematic method of building on what we know) A systematic method of building on what we know. Et: consider jumping frog with four legs removed not responding to verbal order to jump. Lavoisier: when ch4 burned in air, the ch4 disappeared, and there was no change in total mass. If universally consistent (i. e. , patterns or trends are identified), the observations can be stated as a law. Lavoisier"s law of conservation of mass: in a chemical reaction, mass is neither created nor destroyed, equivalent to, in a chemical reaction, matter is neither created nor destroyed. A hypothesis is an explanation of an observation; the explanation must be testable. Frog hypothesis: when frogs have their legs amputated, they become deaf. Lavoisier hypothesis: when ch4 combusts, it combines with components of air. New experiment: combust ch4 in air and analyze products for co2 and h2o.
