Question

introduction to the scientific method worksheet
long ago, many people believed that living things could come from nonliving things. they thought that worms came from wood and that maggots came from decaying meat. this idea was called spontaneous generation. in 1668, an italian biologist, francesco redi, did experiments to prove that maggots did not come from meat. one of his experiments is shown below.

redi placed pieces of meat in several jars. he divided the jars into two groups. he covered the first group of jars with fine cloth. he left the second group of jars uncovered. redi observed the jars for several days. he saw flies on the cloth of the covered jars, and he saw flies laying eggs on the meat in the uncovered jars. maggots appeared only on the meat in the group of jars left uncovered.
questions

1. which is not a step in the scientific method?

a. problem or question
b. research
c. ask other people for their opinion
d. arrive at a conclusion

1. what was the problem in redi’s experiment?

a. how do maggots appear in meats?

Explanation:

Question 1

The scientific method typically includes steps like identifying a problem/question, conducting research, making observations, forming hypotheses, testing hypotheses (experiments), analyzing data, and arriving at a conclusion. Asking other people for their opinion is not a standard step in the scientific method as scientific conclusions are based on evidence from research and experiments, not opinions.

Redi's experiment was designed to investigate the origin of maggots in meat. The common belief at the time was that maggots spontaneously generated from meat, but Redi wanted to test if they actually came from fly eggs. So the problem (question) he was addressing was how maggots appear in meats (specifically, do they come from spontaneous generation or from fly eggs).

Answer:

c. Ask other people for their opinion
