*Chunk notes and develop at least 3 questions that can be answered using your notes.
Aristotle (384-322 BC) was an ancient Greek philosopher- intellectual; lover of wisdom. o
Made many contributions to field of science. o
“Authority” in science and many other fields- what o he spoke as truth was taught in society and universities for over 1,000 years
Logical thinking, made conclusions based on observations
“How did the maggots get on the meat?”
o o o o
Maggots appear on decaying meat if left in
Maggots do not appear on meat that is in a sealed container.
Spontaneous generation- maggots are formed when decaying meat mixes with the air.
Because of Aristotle’s powerful influence, this was accepted as truth.
Problem- Aristotle never performed scientific experiments to support his ideas. He created
“Laws of the Universe” from simple observation and creative reasoning.
Francesco Redi (1626-1697)- Italian biologist who challenged the idea of spontaneous generation. o
Conducted experiments to test Aristotle’s idea. o
Results from scientific tests showed o o maggots would form on mesh lid of jar if meat was decaying inside.
Disproved Aristotle- maggots do not spontaneously generate from meat.
Maggots hatch from eggs laid by flies.
Science is not just a body of knowledge- Science is a process in which we develop tests to gain sufficient evidence to support our claims!
