How can I design a replicable scientific investigation?
reputable source - research site that is trustworthy (e.g. Digital
Library of Earth Science Education, National Science Digital Library,
hypothesis/prediction - an educated guess of what you think is going to
happen in a situations
procedures - a specific sequence of ordered steps
data - the information gathered from observations of an experiment.
conclusion - states whether the data supported the hypothesis.
source of error - a source that affects the results of an experiment
(human error-spilled something, not following directions exactly; environmental
error-impurities in chemicals; instrumental limitations-how specific your
measurement is; trial/sample size-testing to little)
fact - something that can be proven through observation
law/principle - a fact that has always been observed to be true (Law of
Gravity says that when an object is released it will fall and has always been
proven to be true)
theory - an explanation of why something happens that is well-supported
by evidence (plate tectonics is a well supported piece of evidence that
explains continental drift and seafloor spreading)
