Questions and Answers
  • 1. 
    Match to the best fit:The Greeks believed that the world was made up of elements: earth, air, fire, and water.
    • A. 

      1. The underlying assumption in science is that the universe has an independent, external reality accessible to human senses and amenable to human reason.

    • B. 

      2. Scientists use deductive logic when they use a general theory to predict a specific experimental result.

    • C. 

      3. Scientists use inductive logic when they use a specific experimental result to form a general theory.

    • D. 

      4. Improved instruments or new technology have often been drivers of new discoveries.

    • E. 

      5. A new theory can radically change how essential concepts are understood and cause a paradigm shift in how the world is viewed.

    • F. 

      6. Science becomes pseudoscience when it lacks supporting evidence, does not have a theoretical framework, is not done rigorously or in a clear manner, or is not testable and hence falsifiable.

    • G. 

      7. New models in science are being created using powerful computers or complex mathematical equations.

  • 2. 
    Match to the best fit:Beecher came up with the idea that phlogiston was the reason that these four elements have different properties. When something burned, phlogiston went into the air until air could not hold any more phlogiston.

  • 3. 
    Match to the best fit:Lavoisier (the father of Chemistry) used experiments and measuring mass to destroy the idea of phlogiston. He showed air contained different types of air with different properties. More importantly he showed burning took something out of the air 2Hg + O2  --> 2HgO by mass increase and this reaction was reversible 2HgO --> 2Hg + O2. He named this new element oxygen. This paradigm shift opened the way to discover more elements..

    Match to the best fit:Rutherford shot radiation through atoms to discover that a hard dense positive center existed called the nucleus. It was thought the electrons were travelling in orbits.
