Chemistry - The study of atoms and molecules, their structures, and their interactions to form substances computer model - A detailed, complex model calculated by a computer conceptual model - A model used to visualize things that cannot be seen, such as atoms control variable - The variable(s) you don't want to study, need to be either eliminated or kept constant Controlled Experiments -Scientists perform a controlled experiment when they want to find out how changing one thing causes something else to change. dependent variable - The variable that changes because of an independent variable Earth science - The study of the Earth's structure and composition, and processes that change Earth essential attributes of science - Studies the natural world Uses testable ideas Relies on data from observations/experiments Presented for evaluation by other scientists Leads to further questions/research hypothesis - A testable statement about how something in nature worksindependent variable - What you change in an experiment on purpose law - A concise statement that is supported by scientific evidence and repeated experiments, describes a widespread pattern in nature (what) mathematical model - A model that treats physical objects/phenomena using mathematical methods observational studies - field studies, which are done outside a laboratory setting.
