Understanding Concepts Pg. 50-51 Questions 1-9

1. I believe that blood circulating through your body is a definite science. This is dueto the fact that in the definition of science is: looking at and learning about the

natural world and producing a body of knowledge about nature; a process based

on observations, explaining observations, and testing the explanation, we are partof this natural world. Furthermore the observations and stuffy of the body have

their own branch of science called Anatomy.

2. The methods of science that were missing in reaching the conclusion of the true

production of eels were observation of the event, experimentation to demonstratethe truth or falseness of the hypothesis, and a conclusion to validate the

hypothesis. The knowledge I possess today that would lead me to reach such a

conclusion is based on the fact of knowing how reproduction works and that

reproduction can only happen with the sexual or asexual process.3. The formal hypothesis Fleming might have stated If the mold Penicillium killed

a bacteria growing in glassware, then the chemical alone, without the mold, mayalso kill bacteria.

4. The prediction Fleming offered based on his hypothesis, was that the chemical

alone without the mold should also kill the bacteria.

5. I would test Flemings hypothesis by having glassware with the same bacteria ineach and have three test groups; the first being the control group, which would

just have the bacteria; the second group, which would have the bacteria and just

the chemical from the mold; and the final group, which would have the bacteria,and the chemical and mold. Of course all of these groups would have replications

to further test their how valid they are.6. If Fleming had explained his observations stating that the mold sent out evilspirits that caused the death of the bacteria, this explanation would not hold up at

all. It is missing any observations showing the evil spirits killing the bacteria and

no scientific proof therefore, it is a farce.7. Flemings findings showed the relationship between science and technology

because with science he figured out that the mold kills bacteria and with

technology he figured out how to grow the mold in a liquid medium thus making

a relationship between the,8. Flemings explanation was not a law but was a theory. This was because it does

not always kill bacteria and can not have the same effect every single time.

9. It would be a problem if a scientist hurried through his research and was notcareful in reporting and analyzing his data and conclusions in a paper because due

to him rushing he might make errors in the paper making his hypothesis wrong.

Also if others wanted to repeat the experiment they would have a hard time due tothese errors and their conclusions would not be accurate.
