During the next week each lab group will collect data in tables. Once the data is collected your group will have to summarize the data and represent the results using a table and figure.
Step 1: Introduction material before beginning an experiment. Refer to page 4 of your lab manual for a description of the experiment. Notice that page 4 includes introductory information that explains the underlying hypothesis of spontaneous generation. What is the general question addressed by Procedure 1? This step is not included in a formal lab report introduction section. What background information is required to explain your formalized hypothesis?
For the formal lab report you need to find appropriate cited sources to support your hypothesis. Read the procedure on page 4 of the lab manual to determine the independent and dependent variables. Write a formalized hypothesis. Include the dependent and independent variables. Read procedure II on page 5 of the lab manual to determine the independent and dependent variables. Are the independent and dependent variables the same for both procedures?
Are the hypotheses for procedure 1 and procedure II the same? If not what relationship does procedure II test? Experimental Design: Follow the instructions on page 4 and 5 of your lab manual. The following tables are meant to aid in collecting the raw experimental data.
Do not use these tables in the final lab report; follow the example table in the handout on how to write a results section.

A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study. For example, a study designed to look at the relationship between sleep deprivation and test performance might have a hypothesis that states, "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived.
In the scientific method, whether it involves research in psychology, biology, or some other area, a hypothesis represents what the researchers think will happen in an experiment.
The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. It is only at this point that researchers begin to develop a testable hypothesis. Unless you are creating an exploratory study, your hypothesis should always explain what you expect to happen. In a study exploring the effects of a particular drug, the hypothesis might be that researchers expect the drug to have some type of effect on the symptoms of a specific illness.
In psychology, the hypothesis might focus on how a certain aspect of the environment might influence a particular behavior. Remember, a hypothesis does not have to be correct. When conducting an experiment, researchers might explore a number of factors to determine which ones might contribute to the ultimate outcome. In many cases, researchers may find that the results of an experiment do not support the original hypothesis.
When writing up these results, the researchers might suggest other options that should be explored in future studies. In many cases, researchers might draw a hypothesis from a specific theory or build on previous research. Popper eventually became unhappy with both Marx and Freud and their followers because he felt that they were both too quick to "explain away" any evidence that contradicted their ideas. For instance, Marx had predicted that the communist revolution would begin in a highly industrialized country, like Britain or Germany.
Instead, the communist revolution occurred in Russia, which was hardly industrialized at the time, and never spread to the industrialized nations. Marx's followers explained this by claiming that it was due to "unforseen historical accidents" and Marx wasn't actually wrong.
Popper also noted that Freud often used essentially the same explanation to explain vastly different behavior - a brutal murderer was acting under the same influences as a generous philanthropist. Einstein said, in effect among other things , "If you look at stars near the Sun during a total eclipse, you should observe a specific behavior.
If this doesn't happen, my theory is wrong. Popper felt that this was the essence of a real scientific hypothesis. Note that it is very easy to prove Hypothesis C wrong if it were , but it is impossible to prove it correct! Since Hypothesis C states that any pair of objects behaves in a certain way, in order to prove it correct, all possible combinations of objects that exist or have ever, or will ever exist must be tested. This is clearly not possible.
As we test Hypothesis C more and more, we can get more and more confident in its truth, but we can never be absolutely sure. Someone could always come up with 2 objects tomorrow which don't behave exactly as Hypothesis C says they should, and this would make Hypothesis C incorrect. Actually, this almost happened. Just a few years ago a group of physicists published a paper claiming that careful reanalysis of some experimental data published at the turn of the century which confirmed Hypothesis C actually showed that things made of large, heavy atoms fall very slightly faster than things made of small, light atoms.
This "fifth antigravity force" idea caused quite a stir for a short while, but no one has so far been able to confirm this effect. If other physicists had been able to observe it, Hypothesis C would have been proven wrong. It sometimes bothers people that scientific facts, hypotheses, laws, and theories generally can't be proven to be true. This statement gives a possibility if and explains what may happen because of the possibility then.
The statement could also include "may. Notice that all of the statements, above, are testable. The primary trait of a hypothesis is that something can be tested and that those tests can be replicated, according to Midwestern State University. An example of untestable statement is, "All people fall in love at least once.
Also, it would be impossible to poll every human about their love life. An untestable statement can be reworded to make it testable, though. For example, the previous statement could be changed to, "If love is an important emotion, some may believe that everyone should fall in love at least once. A hypothesis is often examined by multiple scientists to ensure the integrity and veracity of the experiment. This process can take years, and in many cases hypotheses do not go any further in the scientific method as it is difficult to gather sufficient supporting evidence.
Then once you collect the data you analyze it to see if your hypothesis is supported or not.
