| Science | to study |
| Chemistry | study of matter and changes it undergoes |
| Matter | Anything that has mass and takes up space |
| Organic | Carbon Chemicals ex; Pharmaceuticals, plastics |
| Inorganic | Non-Carbon Chemicals Ex; Studying metals in simiconductors, minerals |
| Physical-Changes of | Matter and energy Ex; Reaction rates |
| Analytical | Componits of composition of matter Ex; Food nutrients, quality control |
| Biochemistry-Chemicals in | Living things Ex; Meabolism, Fermentation |
| Step 1 | State the problem form of a question detailed and can be answered scientifically |
| step 2 | Research, Gather innfo and plan |
| Step 3 | Hypothesis , educated guess prediction; |
| step 4 | Experiment-test hypothesis |
| Independant Variable | Monipulated Variable; Changed by the scientist |
| Dependent Variable | Changes as it reacts to the independent Variable; What is measured |
| Constant Variable | Any variable that doesn't cfhange. |
| Control group | Used as a conclusion; Only independent variable is different from experimental group |
| Step 5 | Analyze Data, Data is organized in order to find a pattern, Avoid dias ( Expectations affect results) must be repeatable |
| Quantative data | Numerics data; Ex. Formulas |
| Qualititative data | Non numeric data Ex. Unit of measure ment (gathered with the senses) |
| Step 6 | Conclusion; States specially what was found, it can be made into a law |
| Scientific model | Visual, verbal or mathematical representaion of data |
| Theory | Explanation that has been supported by many, many experiments; Still can change with new info. Ex atomic theory , evolution |
| Scientific law | If no exception of the theory is found, it can be made into a law Ex. Gravity |
| pure Reaserch | Research to gain knowledge for the sake of knowledge its self |
| applied research | Research to solve specific problem, chance discoverable, unexpectedly discovering a new conclusion |
| applying science | technology, practical use of scientific info. |
| macroscopic | can be seen with the naked eye |
| microscopic | can be seen with a microscope |
| submicroscopic | too small to even be seen with a microsope |
