Science - "the search for knowledge", the systematic knowledge of the physical or material world gained through observation and experimentation; science is dynamic - in a state of change as new discoveries are made quantitative observation - use numbers or measurements to describe with one or more of your senses; senses may be enhanced with specialized instruments qualitative observation - describe with one or more of your senses using the qualities of something like color; senses may be enhanced with specialized instruments inference - logical process by which new statements are derived from known and observed facts; may or may not be true procedure - steps used in the experiment analysis - using math to make meaning of the data controlled variables - keeping all the other variables the same except the independent variable control - having a treatment in which nothing was done as a comparison for other treatments in an experiment conclusion - a statement about your discoveries in the experiment theory - a well supported explanation in science in which some aspects are still not fully understood hypothesis - an educated guess or prediction that can be tested in science scientific method - the logical process or series of steps by which scientist gather and verify information scientific law - facts or a process well documented and understood in science independent variable - manipulated variable - controlled by the scientist - graphed on the x-axis dependent variable - responding variable - measured by the scientist - graphed on the y-axis technology - using science to make useful things
