Observation & Inference

Observation Power Point

http://rpdp.net/adm/uploads/science/763Observation&Inference.ppt#266,1,Slide1

Is Seeing Believing? Observe black and white and colored

pictures with naked eye, hand lens, and microscope.

Penny Observation

Draw a picture of a penny from memory

Observe a penny for 1 minute and then draw a picture of the penny Use a hand lens

Observe a penny with unlimited time. How did your drawing change each

time?

ObservationsAny information collected with the senses.

Quantitative – measurable or countable 3 meters long 4 marbles 50 kilograms 35 degrees Celsius

Qualitative – describable, not measurable red flowers smells like fresh baked cookies Tastes bitter

The skill of describing scientific events Information collected is evidence or data

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 = ?

Look at these two sets of animal tracks.

Observation / Inferences Piecing Information Together

Read a small section of a cutup book. What facts can you state? What inferences can you make? How would your confidence change if

you viewed more of the book? How does this resemble the work of a

scientist?
