| Observation | The process of gathering information about events or processes in a careful, orderly way. |
| Data | The information gathered from observations. |
| Inference | A logical interpretation based on prior knowledge or experience. |
| Hypothesis | A proposed scientific explanation for a set of observations. |
| Spontaneous Generation | The idea that life could arise from nonliving matter. |

| Microscope | Devices that produce magnified images of structures that are too small to see with the unaided eye. |
| Compound Light Microscope | A device that allows light to pass through a specimen and uses two lenses to form an image. |
| Electron Microscope | A device that uses beams of electrons to form an image. |
| Cell Culture | A group of cells. |
