| Data | "The facts or information that I gather during an experiment; for example, I measure the height of plants every day." |
| Variable | "The factors that can change in an experiment." |
| Scientific Inquiry | The way that scientists ask questions about the natural world. |
| Inference | "I interpret my observation and make a judgment; for example, polar bears may have white fur because they live in a snowy habitat." |
| Manipulated Variable | "The variable I control; for example, how much fertilizer a plant gets." |
| Controlled Experiment | "An experiment where only one variable is changed." |
| Scientific Theory | A well tested concept that explains a wide range of observations. |
| Constant | The parts of the experiment that stay the same. |
| Responding Variable | "The variable that may change; for example, the height the plants" grow. |
| Hypothesis | "A possible explanation for a scientific question; the format is: If… then…" |
| Observation | "I use my senses to gather information; for example, I notice polar bears have white fur." |
| Science | A way of learning about the natural world. |
