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
