| experimental group | "AKA the guinea pigs" -- the real test group in an experiment |
| observation | something noted in an experiment or noticed about the world around you using your senses |
| control group | part of an experiment treated "normally" -- used to compare experimental results |
| hypothesis | untested idea, an educated guess why one variable effects another |
| theory | an idea in science with at least some evidence or observations supporting it, useful in making predictions |
| direct observation | an observation made on something you can see or measure "firsthand" |
| indirect observation | observation about something you can't see or measure "firsthand" -- you must observe HOW OTHER THINGS ARE AFFECTED |
| law | idea in science proven correct repeatedly without exception |
| inference | a conclusion or explanation based on observations made about something |
| scienctific method | steps often used in solving problems in science (can be helpful in solving any problem) |
| experiment | used to test a hypothesis |
| procedure | something DONE in an experiment |
| science | search for the true nature of the world and how it works based on our observations of it |
| prediction | a statement on how one variable effects another |
| dependent variable | AKA the responding variable |
| dependent variable | the variable that changes in response to a change made to the independent variable |
| independent variable | AKA the changing variable |
| independent variable | the variable that is changed in a experient |
| variable | a condition that one change change or alter in an experiment |
| qualitative observation | observations based on only your senses and they are not measurable (i.e. no numbers) |
| quantitative observation | observations are made with instruments such as rulers, balances, graduated cylindars. These are measurable (i.e. have numbers) |
