| Observation | Using one or more of your senses to gather information about the world |
| Most basic skill in science | Making and recording observations |

| Qualitative Observation(s) | are descriptions that do not use numbers; For example: colors, smells, tastes, textures or sounds |
| Quantitative Observation(s) | do include numbers; Counting objects, or measuring something with a standard unit; Often made using tools |
| Inferring | Making an inference, or inferring, is explaining or interpreting an observation or statement; It is based on observations and prior knowledge; Inferences should be reasonable (logical),one that makes sense, given what a person knows about the topic and be based on accurate evidence; • An inference may be unreasonable if it concludes too much from the evidence and should be avoided; |
| Predicting/Making a hypothesis | Predicting is making an inference about a future event based on current evidence or past experience; It is not a guess. One way to make a prediction is to look for a pattern. Because a prediction is an inference,it may not always be correct. • Predictions can be tested by observation and/or experimentation. |
