4. Types of Scientific Investigations
Pure research is research to gain knowledge for the sake of knowledge itself.
Scientists Molina and Rowland were motivated by curiosity when they conducted their research on CFCs and their interactions with ozone.
No environmental evidence at the time indicated that there was a correlation to their model in the stratosphere.

5. Types of Scientific Investigations
Applied research is research undertaken to solve a specific problem.
Scientists continue to monitor the amount of CFCs in the atmosphere and the annual changes in the amount of ozone in the stratosphere.
Scientists continue to conduct research to find replacement chemicals for CFCs that are now banned.
Chance discoveries occur when scientists obtain results that are far different from what they expected.
Example: Alexander Fleming’s discovery of Penicillin.
