| A | B |
|---|
| Product | A substance that is produced by a chemical reaction. The final result |
| Properties | Used to identify and group matter (same as characteristics) |
| Chemical Change | A process in which the physical and chemical properties of the original substances change as new substances with different physical and chemical properties are formed |
| Physical Property | Any characteristic of a material that can observed without changing the identity of the material |
| Viscosity | Resistance to flow |
| Matter | Has mass and takes up space |
| Exothermic | Type of chemical reaction in which heat is produced |
| Reactant | A substance that enters into a chemical change |
| Controlled variable | A factor or condition that stays the same |
| Quantitative | Observations involving number |
| Qualitative | Observations involving your senses |
| density | mass divided by volume |
| Chemical Change | A change where new substances are formed which has new properties different from the original substances |
| Endothermic | Type of chemical reaction in which heat is absorbed or taken in |
| Physical changes | A type of change that is reversible (the new substance is the same as the original substance) |
| Solid | State of matter that has a definite shape |
| Gas | State of matter that can be invisible |
| Manipulated variable | factor or condition that changes or is altered on purpose by the scientist |
| Responding variable | factor or condition that changes (or does not change) in response to the manipulated variable |
