 “Vast body of saline water that occupies the depression of Earth’s surface.”  >97% of all water is oceanic  <3% is contained in lakes, groundwater, land ice, etc. What is an ocean?

 “Science interprets raw information by constructing a general explanation with which the information is compatible.”  It all starts with a question. Start at the root of it all: Science

 Question  Hypothesis  Experiment(s)  Repeat  Theory  Law Scientific Method

 Most famous for Origin of Species and work with theory of evolution  HMS Beagle  Marine biologist  Natural selection Charles Darwin

 Sir John Murray  Inspired by Darwin’s discoveries  Mission: to prove Edinburgh professor’s theory that life below 1800 feet was impossible  Discovered over 4,000 new species!  Thus marine biology was born HMS Challenger

 On a piece of paper write down a question you have about the ocean. Follow the question with your hypothesis and an experiment that you may use to test your hypothesis. Homework
