Observation

Observation: when studying something describe only facts that you can see, touch, smell and hear. You are not making any guesses. THIS IS NOT AN OPINION!!

Ohh… This liquid is green and it is leaking from a brown can. I also smell it.

Observations• Any information collected with the senses.

» 3 meters long» 4 marbles» 50 kilograms» 35 degrees Celsius» red flowers» smells like fresh baked cookies» Tastes bitter

• The skill of describing scientific events

Inference

Inference: using your observations to make a guess about an object or an outcome

THIS CAN BE A SCIENTIFIC OPINION

Based on my observations, I think that this can is old and is leaking a toxic substance.

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 = ?
