On your sheet of paper divide it in half. Observation Definition: Inference Definition:

Observations Any information collected with the senses. Quantitative – measureable or countable »3 meters long »4 marbles »50 kilograms »35 degrees Celsius Qualitative – describable, not measureable »red flowers »smells like fresh baked cookies »Tastes bitter »Heard a loud “pop” The skill of describing scientific events

Inference Conclusions or deductions based on observations. The process of drawing a conclusion from given evidence. Practice: Observations: I hear people screaming I smell cotton candy, popcorn, and hamburgers I see a lot of people Inference = ?

Write 3 observations and 3 inferences under the appropriate column.
