BIO 10 Lecture 1. HOW SCIENTISTS VIEW THE WORLD. Which of the following statements best describes SCIENCE?. Science is a collection of facts about the Universe and how it behaves Science is a collection of theories that have predictive power
HOW SCIENTISTS VIEW THE WORLD
Scientific factsare irrefutable statements about nature such as “The Earth is spherical, not flat.”
Although it certainly appears to the casual human observer that the Earth is flat, we now KNOW, as a fact, that this is not true.
At one time, the idea that the Earth was a sphere was merely a THEORY based on certain observations. For example:
Sailors observed that the tops of mountains and buildings come into view above the horizon before objects nearer to the ground
Scientific theories the shadow of Earth on the Moon during the partial phase of a lunar eclipse is circular.are sets of general principles, supported by facts, that have predictive power.
“The Universe started with a Big Bang.”
Although the theory of the Big Bang has a great deal of explanatory power, it cannot be directly observed, and it still cannot explain some of the key observations in physics …
My husband produces the smelly substance in his urine after he eats asparagus but lacks the ability to smell it.
Evidence against spontaneous generation: 1. Unsealed – maggots on meat 2. Sealed – no maggots on meat 3. Gauze – few maggots on gauze, none on meat
1. How is science different from other methods of gathering information? (E.g. casual observations, book-learning, listening to parents, teachers, or friends, reading the Bible)
2. State a hypotheses that cannot be subjected to scientific analysis.
3. Does science ever prove anything? Give one example.
