| science | the investigation and exploration of natural events and of the new information that results from those investigations |
| life science | the study of all living things |
| earth science | the study of Earth, including Earth’s landforms, rocks, soil, and forces that shape Earth’s surface |
| physical science | the study of chemistry, physics and of the interactions of matter and energy |

| scientific method | a series of steps that scientists use to answer questions and solve problems |
| observation | the use of the senses to gather information |
| inference | an interpretation of an observation that is based on evidence or prior knowledge |
| prediction | a statement about what will happen next in a sequence of events |
| hypothesis | a possible explanation or answer to a question made by info you already know or info gathered from observations; an educated guess |
| variable | any factor in an experiment that can have more than one value |
| independent variable | the factor that is changed or that you want to test |
