- believe questions can be answered
Steps of the Scientific Method. Answer: 1) Make an Observation
2) Ask a question
3) Form a Hypothesis ("if, then" statement)
- accept (agree with conclusions)

- has been developed/tested/scrutinized/challenged/ reviewed, etc.
, - generally accepted by whole scientific community
- ie: theory of gravity, atomic theory of matter
pH. Answer: - measures acids and bases
- scale from 0-14
-acids ( H+ ions): range from 0-6/7
-neutral : 7
- basic (OH- ions) 7/8-14
- most of what we eat or drink is acidic; household cleaners, etc. are
most likely basic

experiment
- tested whether life could arise spontaneously
- living things vs. biogenesis (came from life)
- took 4 different animals and used a control group (covered it from
flies)
- findings were not accepted at first; idea of spontaneous life did not
