Discovery Science n n Descriptive Observes and collects data that describe natural structures or processes

What do you observe? Similarities/Differences?

Examples of Discovery Science n n n Mapping of the human genome Accidental discovery of antibiotic penicillin by Alexander Fleming Identifying new species of plants and animals

Type of Data Discovery Science collects n Two types Qualitative – observations in form of descriptions- color , shape, behavior n Quantitative – observations based on measurements, collection of numbers n

Qualitative vs. Quantitative data. Hold up 1 finger for qualitative and 2 for quantitative n n n You measure the blood pressure of a rat Jane Goodall studies the behavior of chimpanzees Condition of an organism How something smells p. H of a substance Growth of an organism 10

Qualitative vs. Quantitative data Answers You measure the blood pressure of a rat Jane Goodall studies the behavior of chimpanzees Condition of an organism How something smells p. H of a substance Growth of an organism Items in red are best displayed using qualitative data 11

Closure Activity n Now YOU think of another example of Discovery Science. Explain your reasoning.
