scavenger: type of detritivore that feeds on carrion (dead animal remains). examples: vultures, sharks, maggots, hyenas, etc.
scientific method: series of steps scientists use to determine the unknown: (Q, R, H, E, A, C, C) = Question, Research, Hypothesis, Experiment, Analysis, Conclusion, Communicate.
shape: the structure of an organism.
single displacement/replacement: 1 of 5 chemical reaction types we'll explore, this one is identifiable by presence of one lone element on both the reactant and product sides; left alone after one bond is broken and a new partnership is made; "one partner switch" (ex. AB + C > AC + B).
solid: state of matter, definite shape and definite volume.
solubility: the ability to dissolve.
soluble: able to dissolve.
solute: substance that is dissolved into another.
solution: a homogeneous (evenly distributed) mixture of two or more substances uniformly dispersed.
solvent: substance that is already present; the solute is applied to this substance.
speed: distance an object travels per unit of time.
sublimation: phase change, from solid to gas.
subscript: lower number in a chemical formula; indicates the number of atoms of a particular element that are present. (ex. N2O, there are 2 atoms of Nitrogen and 1 atom of Oxygen in this molecule)
support (hypothesis): conclusion made if, your data "agrees" with your hypothesis.
surface tension: force that acts on the surface of a liquid and that tends to minimize the area of the surface.
suspension: mixture with particles of its material that are mostly evenly dispersed throughout a gas or liquid.
symbiosis: relationship between two organisms that live close together.
synthesis: 1 of 5 chemical reaction types we'll explore, this one is identifiable by the LARGE product and two or more smaller reactants; the product is built and in one piece (ex. A + B > AB ).
