Name, Term, or ConceptDescription/Definition
counter-example an example that contradicts a conclusion
hypothesis an educated guess that attempts to explain an observation or answer a question
theory a hypothesis that has been tested with a significant amount of data
scientific law a theory that has been tested by and is consistent with generations of data
True or False: Science can never prove anything. True
True or False: Heavier objects fall faster than lighter objects. False
air resistance refers to the fact that air actually slows objects as they fall (Sir Isaac Newton)
True or False: In the absence of air, ALL objects, regardless of weight or shape, fall at the same rate. True
What does it take to destroy a scientific law? A single counter-example.
Steps of the Scientific Method 1. Make observations 2. form a hypothesis 3. perform experiments to confirm the hypothesis 4. hypothesis is now a theory 5. perform many experiments over several years 6. theory is now a law
What are the three limitations of science? 1. it cannot prove anything 2. it is not 100% reliable 3. it must conform to the scientific method.
Percival Lowell hypothesized that the criss-crossed line observed on Mars were actually canals used for water distribution.
superconductors substances that conduct electricity without reducing its energy as it passed through
Heike Onnes Dutch scientist who discovered low-temperature superconductivity
Bednorz and Muller German scientists who discovered high temperature superconductors and refined Onnes' theory
Is the existence of Halley's comet a theory or scientific law? a scientific law: because it has been observed many times throughout history by many different scientists.
Can any subject be studied by science? Yes, as long as the scientific method is used.
observation Allows the scientist to collect data
What was the experiment that confirmed Halley's hypothesis? The experiment to confirm the presence of the comet again in 1758.
If a hypothesis does not agree with the experiment designed to confirm it, what two choices do you have? You can either discard the hypothesis or modify it to become consistent with the data.
If a theory does not agree with the experiments designed to test it, what two choices do you have? You can either discard the theory or modify it to become consistent with the data.
