Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it?
MERGE exists and is an alternate of. What did Francesco Redi show in his experiment? Francesco Redi found out in his experiment of were maggots came from that they came from flies and not dead meat.
But you can do a descriptive study that presents all the facts. For example, you can talk about the gravitational attraction between the earth and moon, and about the orbiting of the moon around the earth.

|Related eponyms||Francesco Redi disproved spontaneous generation for large organisms by showing that maggots arose from meat only when flies laid eggs in the meat. Spontaneous generation for small organisms again gained favor when John Needham showed that if a broth was boiled presumed to kill all life and then allowed to sit in the open air, it became cloudy.|
You could look at the overwhelming amount of data supporting the moon-tide link, or see if anyone has ever proposed another explanation for tides. What you end up with, essentially, is a perfect correlation between tidal events and the movement of the moon.
Maybe you could explore when and how correlations like this really do provide a strong argument for cause and effect.
That might be an interesting thing to explore!. Just had another thought. You could take a piece of cloth completely soaked in water and demonstrate that if you suspend it and leave it untouched, the top of the cloth will dry before the bottom does. You start by assuming the gravitational attraction between the wet cloth and the earth, but you demonstrate that the water will act independently, and not stay stuck where it is on the cloth.
It will take some reading and thinking to figure this one out. His experiment was designed to disprove spontaneous generation. It was to answer whether or not Spontaneous generation is possible or not. The theory for spontaneous generation refers to the idea that lifecan produced from nonliving things.
Lazzaro Spallanzani proposed inhis experiement that air was necessary for spontaneous generation. What experiments show that sulfuric acid is dibasic?
Can anyone give the method and calculations to this titration experiment please?
I personally reckon that this is your AS chemistry planning exercise lol Do it yourself!!! He believed in the concept of abiogenesis a-not-bio-life genesis-origin Experiment that shows how a substance is made up of other substances?
For example, it could be shown that water is made of other substances by electrolysis, that separates it into oxygen and hydrogen. Describe an experiment to show air has mass? Pump it up and weigh it again. Its weight will be greater with air in it.
If you increase the air pressure, it will weigh even more. Blow up two balloons. Tie one balloon to each end and hang the ruler from a string so that it balances. The end with the full balloon will go down. What did the experiments of griffith Avery and Hershey and chase show?
The culmination of experiments proved DNA contains hereditary information. Not until Griffith first recognized a "transformation principle" during his work with viruses was DNA considered to contain hereditary information.
Very few biologists however believed from his work alone that DNA contained hereditary information. Later Hershey and Chase took a radical approach with radio-tagging phosphorous and sulfur molecules in viruses to determine which of the two were passed on to offspring.
What kind of experiment was the Truman Show? It was an experiment by Hollywood to see if they could push a severly average film past lots and lots of people, making huge amounts of money off the back of a duff film.
What experiment shows how pH affects enzymes? For the control, take one of the paper slips, using the tweezers, and dip it into the catalase, then place the catalase covered slip at the bottom of a beaker filled about halfway with hydrogen peroxide.
You cannot simply drop the slip into the beaker, you must stick the tweezers into the beaker so that they reach the bottom, and then release. When the catalase contacts the hydrogen peroxide the hydrogen peroxide will release oxygen as a reaction, these oxygen bubbles in the liquid will push the paper to the top.
Start the stop watch precisely when the strip enters the hydrogen peroxide, to measure the rate of reaction, and stop it again when the slip reaches the top.What were the possible conclusions reached from Spallanzani’s experiment?
Why were his conclusions not accepted? -After boiling the broths no bacteria was present. Although his experiment was successful, his conclusions were not accepted because he had deprived the sealed flasks of air by melting their glass necks and it was thought that air was necessary for spontaneous generation to occur.
American graduate student, Stanley Miller, and his professor, Harold Urey, set up an experiment using Oparin's hypothesis What did Miller and Urey make?
Miller and Urey made an apparatus with a chamber that contained the gases Oparin assumed were present in the Earth's atmosphere. Spallanzani's Experiment Lazzaro Spallanzani, also an Italian scientist, reviewed both Redi's and Needham's data and experimental design and concluded that perhaps Needham's heating of the bottle did not kill everything inside.
The second centenary of his birth also was celebrated by addresses published in Onoranze a Lazzaro Spallanzani nel II centenario dalla nascità (Reggio Emilia, ), the most notable being a detailed review of his travels by G. Pighini, “Lazzaro Spallanzani viaggiatore,” pp.
1– In the University of Pavia was host to a meeting of. SPALLANZANI, LAZZARO (metin2sell.comano, Italy, 12 January ; metin2sell.com, Italy, 11 February ) natural history, experimental biology, physiology..
Among the many dedicated natural philosophers of the eighteenth century, Spallanzani stands preeminent for applying bold and imaginative experimental methods to an extraordinary range of hypotheses and phenomena.
Q: Describe the experiment of spallanzani Question 1: what were the possible conclusions reached from spallanzani's experiment? why were his conclusions not accepted? Question 2: why would aristotle's thoughts on spontaneous generation be considered nonschientific reasoning?/5(K).
