| inductive reasoning is _________. | Using creative thinking to combine isolated facts into a cohesive whole, to come up with a hypothesis. |
| hypthesis - | possible explanation for a natural event |
| deductive reasoning - | use4d to test a hypothesis using if, then, logic |
| experimental design - | manner in which a scientist intends to conduct an experiment. |
| control group - | goes through all the steps of an experiment but is not exposed to the factor being tested. |
| conclusion - | whether or not the hypothesis is true or false. |
| experiments and observations must be... | repeatable by any scientist, to get the same result |
| scientific theories - | concepts that join together well supported and related hypothesis. |
| principle (or law) - | theory, but is trusted by a ton of scientists. is accepted as true. |
| independent variable - | factor of the experiment being tested. |
| dependent variable - | result or change that occurs due to the independent variable. |
