Observations
How we look at things in science
What is observation?
• Observations are made in science. They are made by using:
• Senses • Tools
– increase accuracy & precision • Facts not opinions.
Two types of Observation
• Qualitative
• Quantitative
Qualitative Observations
• Hard to measure• Describes the qualities of something
– Color– Taste– Sound
Quantitative Observations
• Can be expressed in numbers• Can be counted or measured
– Amounts– Temperature– Mass – Length
• Allow us to communicate specifics• Tools are used to communicate data• Observations are collected in data tables
Inferences
A statement based on your interpretation of the facts
Look at the chart above and say the COLOR of the word, not the word
itself.
Because the right half of your brain
is trying to say the color, while the left side of your brain
is trying to say the word.
Why is it so difficult?
Inference
• Drawing a conclusion based on data and observation
• 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 = ?
