Redi and the Scientific Method

What was the name of the theory that living things could come from non-living things?

• Biogenesis

• Spontaneous Generation

• Abiogenesis

• Astral Seeding

Every hypothesis at MMS should include the following format:

​ (a)   I do something​ (b)   something will happen ​ (c)   for this reason.

• If
• Then
• because
• beleive
• think

What might Redi use as the BECAUSE of his hypothesis:

IF I place meat in an open jar, THEN maggots will appear on the meat BECAUSE

• The flies can reach the meat to lay eggs

• It is fresher

• It smells worse

• Maggots don't come from flies

In Redi's Experiment, what was the Independent Variable

• Temperature of the environment
• Duration of the experiment
• Whether the jar had a lid or not

• Type of jars used

What would be the dependent variable in Redi's Experiment

• They type of meat

• The type of lid

• whether there were maggots or not

• The size of the jar

Which would be an example of Quantitative Data?

• The fish is red

• there were 5 petals on the flower

• The patient looked sick

• The plant smelled like rotting meat

Sort the data into the correct categories

Groups:

,

(b) Qualitative

• The plant grew 13 cm in 2 weeks

Which type of data would Redi have collected?

• Qualitative

  The smell of the meat

• Quantitative

  The number of flies

• Quantitative

  The number of Jars

• Qualitative

  the color of the gauze

Why would Redi use 5 jars? Isn't 1 jar enough?

• He had a lot of extra meat to get rid of

• He only had five jars

• His lucky number is 5

• The more trials you do of an experiment the more reliable your results

It is okay if your data does not support your hypothesis

• Yes it is

• No it is not
