His initial experiments, boiling broths within closed containers to prove that nothing grew within, was first to help disprove the theory of spontaneous generation. This led to a secondary discovery that micro-organisms were responsible for the spoiling of drinks like beer and wine. This lead to the process now known as pasteurization, which helped purify milk of most moulds and allowing it to keep for much longer.

Describ Mendel's first set of experiments?
In his first set of experiments, Mendel crossed purebred pea plants with different traits, such as tall and short plants. He observed the inheritance patterns in the offspring of these crosses over several generations. Mendel showed that traits are inherited independently and proposed the laws of segregation and independent assortment.
Describe mendel's second set of experiments?
he drew a table and decided to count the number of plants with each trait that turned up he thought it might help him to explain his results
Can a falsifiable hypothesis be tested?
Yes, a falsifiable hypothesis can be tested because it can be proven true or false through experimentation or observation. If evidence is found that contradicts the hypothesis, then it can be disproven. This process is essential in the scientific method to advance knowledge and understanding.
Compare and contrast a theory with a hypothesis?
A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of facts that have been repeatedly confirmed through observation and experimentation. A hypothesis, on the other hand, is a specific, testable prediction about what will happen in a given set of circumstances. In simple terms, a theory explains why something happens, while a hypothesis predicts what will happen.
How does a hypothesis help scientist understand the natural world?
A hypothesis helps scientists to answer questions they have in this world which technically helps them to understand the natural world we live in.
What do scientists perform after making a hypotheses?
They set out to test a hypothesis by using experiments and controls. They then adjust the experiments and run the tests again until they either prove or disprove it.
A scientific explanation for a set of observations that can be tested in ways that support or reject it?
A scientific hypothesis is a proposed explanation for a set of observations that can be tested through experiments or data collection. If the collected data supports the hypothesis, it is considered valid; if not, the hypothesis is rejected or modified. This process helps scientists understand natural phenomena and develop theories that accurately represent the world.
What are the first four steps to scientific method?
The first four steps of the scientific method are: Observation - Noticing and describing a phenomenon or a set of data. Question - Formulating a specific question based on the observations. Hypothesis - Proposing a testable explanation or prediction that addresses the question. Experimentation - Designing and conducting experiments to test the hypothesis and gather data.
What is a scientific explanation for a set of observations that can be tested in ways that support it or reject it called?
A scientific explanation for a set of observations that can be tested in ways that support it or reject it is called a hypothesis. A hypothesis is a proposed explanation for a phenomenon that can be tested through experiments or observations to determine its validity.
Why is a possible explanation for a set of observations called a hypothesis?
A hypothesis is your first guess at how something/ your experiment is going to turn out. If the results you get match your hypothesis you can declare that it provides evidence to suggest that your hypothesis is true.
Why would a scientist change their hypothesis?
In the face of evidence. A Hypothesis is an idea about how something works or will work. Once a test is performed (normally an experiment or a set of observations) then the hypothesis might need to be "refined" or changed to explain the new data. Once a Hypothesis survives all the experiments that people can throw, by correctly predicting their outcomes, then it becomes the "Accepted Theory" for the problem.

Is a scientific hypothesis set in stone?
No, a "hypothesis" is a geuss. In an expirement, a scientist will come up with a hypothesis, and then see if it is true. Therefore, a hypothesis is NOT set in stone until proven.
Why do scientists use experimenting as a method of research?
Experiments can be used to test a hypothesis. For example, an ecologist may set up an artificial environment in a lab to imitate and manipulate conditions that organisms would encounter in the real world. Scientists use experiments to manipulate variables until they find the answer to their question. This is all part of the scientific inquiry.
What are the 5 steps in designing an experiment?
In this order: -State the problem/ ask question -Form a hypothesis -Set up a controlled experiment -Record results - Analyze results -Draw a conclusion -Publish results
Is it necessary for every reserche project to have a set of hypothesis?
yes it is necessary for every research project to have a set of hypothesis
What is a a possible explanation for a set of observations or answer to a scientific question?
In the scientific world that could be a theory, hypothesis, qualitative observation, prediction, or an inference. You can choose one.
