Scientific Methods • There is more than one way to test a hypothesis, such as through a/n experiment or a/n observational study • In order for a controlled experiment to be valid, it must consist of several parts such as a/n independent variable, (also known as a test variable), the dependent variable (also known as a outcome variable), constants, and possibly a control group. • When the results of an experiment are not what was originally expected, we say the results do not support the hypothesis. When the results are as expected, we say the results support the hypothesis. • When the results of an experiment fail to support the hypothesis, the results are still valuable because they lead to further investigation • Replication is repeating another scientist’s experiment to verify results • Repetition is repeating your experiment to verify results
Scientific Methods • Both replication and repetition are important because they make an experiment valid. • Models can be used when something is too big, small, dangerous, expensive etc. • Give an example of technology that is used from science: drones, robots, computers, calculators • The word empirical means from data experiments or observations • An example of scientific knowledge changing in history is: atomic model, def. of planets, solar system (helio vs geocentric) • A law is a rule that describes a pattern of nature. Laws do not change. • A theory is an explanation of observations or events that is based on knowledge gained from many observations and investigations. Theories can change with new information. • Give some examples of scientific laws you have learned: Newton’s Laws, Kepler’s Laws, Law of Conservation of Mass, Thermodynamics • Give some examples of scientific theories you have learned: Big Bang, Continental Drift, Evolution
