*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

Evidence-

Maggots appear on decaying meat if left in

 the open.

Maggots do not appear on meat that is in a sealed container.

Claim-

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

Evidence-

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.

New Claim-

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!
