What is a Researcher? By Karin Patzke (with lots of help from and thanks to Dr. Daniel Calleri at University Of Chicago Lab School)
Research is…. • Explore the world • Ask questions • Observe, Collect Data, Present Evidence. • Identify a problem or something interesting in the world that you want to know more about • Communication and Collaboration • Context – what else is going on? • Situate knowledge in a particular time and place • Alternatives – how can we explain what we see? • Results: Finding and Communicating solutions to problems in the world
Research and Theory A theory accounts for many facts and attempts to explain a great variety of phenomena. Any theory has a large body of evidence (from several disciplines) to support it. And a theory allows you to make predictions which then you can test. A theory can be composed of one or many hypotheses. Shorter definition: how we arrange our research (our facts!) to make sense of our observations (the world!). Theory of Gravity, Heliocentric Theory, Theory of Plate Tectonics, Quantum theory Atomic theory, Evolutionary Theory…… Thanks to Dr. Daniel Calleri for this slide!

What is theory and research for Darwin? 23 years to publish his theory
Darwin From simple Questions: “I wonder why these creatures no longer exist?” “Why such beauty when no one can see?” To more complex: “If the globe has undergone such profound changes in it’s history (geology), surely all living creatures must have changed with it – to adapt to their new conditions?” Questions!
Darwin’s contributionsto evolutionary theory: • Rejected the notion of a constant world: things werechanging (speciation) • Multiplication of species: organisms (living & extinct) descended from ancestral species • Natural Selection provided a mechanism for evolutionary change in populations • NS is a theory that accounts for all the evidence. Darwin hypothesized that is took thousands and millions of years, others have since claimed it happens much faster (or much slower…). Thanks to Dr. Daniel Calleri for this slide!
