Scientific Method
The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What does results mean for science projects?
This is the outcome, the data you got from your project. For instance, if you did a project comparing different fertilizers for use in growing flowers, your results would be how high (on average) your flowers grew in each different fertilizer.
Why isn't a luck-based hypothesis considered to be science?
"Luck" is actually a core element of science. Although, perhaps written in a different light.
Everything is based on statistics. For any occurrence, there is a statistical probability that it will and will not occur. In many senses, a toss of a coin.
In a sense, this is akin to luck.
People create a confidence interval to describe this aspect. Something doesn't have to happen all the time. In fact an occurrence can be quite rare. One just has to have a 95% confidence that one's experimental variable is related to confirm a hypothesis.
Consider smoking for example.
Not all smokers develop lung cancer. Actually those that develop lung cancer are in the minority.
And, some non-smokers will develop lung cancer.
However, smokers develop lung cancer at a higher rate than non-smokers. And, this is a statistical difference.
One can isolate some genes that will predispose one to develop lung cancer, in effect increasing the risk. And, these genes plus smoking will make it more likely to occur.
But, when it comes down to it... it all hinges on luck. A coin toss... A roll of the dice... on whether or not one gets the cancer. One may take actions to weight the dice against oneself, but it still hinges on a roll of the dice.
Discuss why experimental results must be reproducible in order to be considered valid?
If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.

The scientific method uses observations and wich other process to answer questions?
Observations, erecting a hypothesis, and then experimentation to answer questions in science.

What are the characteristics of all scientific theory?
A scientific theory is either (1) an explanation of why or how something happens in nature (physical sciences), or (2) an accepted body of statements that is all we know at present about something (mathematics).
Most theories in the physical sciences involve technical knowledge, such as a mathematical description of things, and\or statements of laws. (But laws are not theories, they are patterns of occurrences in nature.) In the physical sciences, a scientist trying to explain something may make one or more hypotheses, as educated guesses; these hypotheses are then tested in some relevant way to try to refute them. The one that passes the most tests becomes the reigning theory.
Other features of theories are that they explain the largest amount of relevant data, and that they explain it parsimoniously or "prosaically." This means that they obey "Occam's Razor:" they explain the data without needlessly postulating new entities or processes in the world. (It's named after William of Occam, a British philosopher of the 14th century A.D. who thought it up.)
Most theories are tested by making "testable predictions;" the theory or scientist makes predictions of events and\or entities that no one has detected yet, and a relevant test is made to see if the event or entity really does happen or exist.
Examples of Theories And Other Related Information:
(1) Relativity theory: This is the theory of Albert Einstein; it involves a mathematical description of the four dimensional manifold called "space-time," and the theory says that a gravitational field "warps" the space-time around a massive body; this is an explanation of gravity and its effects. Relativity was tested by measuring the positions of certain stars that were close to the sun, before and during an eclipse. Einstein had predicted that light-rays passing close to a massive body like the Sun would be bent by the gravitational field of the Sun. It was seen that the positions differed by amounts that were close to the predictions of the theory. The theory also accounted for an anomaly in Mercury's orbit, and it did away with the "luminiferous ether." (This was a substance thought to permeate all space in the universe.) So the theory explained a little more than Newton's, and it was more "prosaic" than its predecessor (Newton's theory could not account for everything about Mercury's orbit).
(2) Theory of Natural Selection: This is the theory of Charles Darwin that says that the advent of all species in nature is the result of Natural Selection. Darwin said that Natural Selection was analogous to the selection that people do when they breed animals and plants. Certain inherited features of organisms make them better adapted to their environment, and so those species stay long enough to leave progeny, while other species are maladapted to the environment, so they become extinct. Changes in the inherited characteristics, if allowed long enough to accumulate, lead to new species. The theory was tested against its rivals, and also tested in genetics laboratories. One testable prediction it made was about the age of the Earth. Darwin held out against the verdict of the physicists of his day; they said that the Earth can only be hundreds of thousands of years old, while Darwin, given what he knew about the pace of evolution, said it must be in the hundreds of millions of years old. He proved to be right- it's in the billions, 4.5 billion years old to be exact. The theory proved also to be more parsimonious: it eliminated the older theory of Lamarck, who said that acquired characteristics are passed on to an animal's progeny (e.g., if a giraffe tries really hard to reach the highest buds on a tree and its neck stretches, it passes the longer neck on to its offspring.), it eliminated the "scale of nature," which was the idea that we human beings are the pinnacle of creation, and it eliminated the older idea that evolution or creation is "trying" to make us human beings.
What hypothesis can you use for a middle school science fair project?
A hypothesis is your best educated guess on what the outcome of the science fair project is going to be. So you would first need to come up with the science experiment that you want to do before you can come up with your hypothesis. Example: if your science project was mixing baking soda and vinegar together to see what type of reaction you will get, your hypothesis is your guess on what is going to happen when you mix the baking soda and vinegar together. So my hypothesis for that experiment of mixing baking soda and vinegar together is that it will foam up and overflow from the container that I mixed them in. If that happens then my hypothesis was correct. So you need to have an experiment in mind before you can make your hypothesis for the experiment.
How is the scientific method important in scientific investigation?
The scientific method is important in scientific investigation because it helps to test predictions (hypotheses).
The scientific method has been very effective in advancing scientific knowledge. Scientists have learned a tremendous amount about our universe, by making use of it. Therefore, the scientific method has proved its value.
Who is the inventor of the Scientific Method?
Some of the earliest influences on what we now consider the scientific method were by the Greeks, notably Aristotle(384-322 BC) and Archimedes (287-212 BC).
During the "Islamic Golden Age", important contributions were made by Geber (Abu Musa Jābir ibn Hayyān al azdi, 721-815), Alkindus (Abū Yūsuf Yaʻqūb ibn Isḥāq al-Kindī, 801-873) and especially by the Arab scholar Alhazen (Ibn Al-Haytham, 965-1039).
Later Persian scientists expanded on experimental methodology, including Al-Buruni (Abū Rayhān al-Bīrūnī) and Avicenna (Abū Alī Sīnā).
The coming of the European Renaissance provided insights by Robert Grosseteste in the 12th Century, Roger Baconin the 13th, and Galileo (1564-1642).
Francis Bacon was the first to formalize the concept of a true scientific method, but he didn't do so in a vacuum. The work of Nicolaus Copernicus (1473-1543) and Galileo Galilei (1564-1642) influenced Bacon tremendously.
Francis Bacon
It grew gradually during the Renaissance, when it was realised that just saying 'God made things' was not sufficient explanation.

What are the Advantages of participant observation?
Participant observation allows researchers to gain an in-depth understanding of the subjects' behaviors and perspectives by directly immersing themselves in their social context. It also provides rich, detailed data that may not be captured through other research methods. Additionally, participant observation can help build rapport and trust with participants, leading to more authentic insights.
What is the negation and interchanging of the hypothesis?
When the negation of the hypothesis is switched with the conclusion, this is referred to as contrapositive. When the hypothesis and the conclusion are switched, this is called converse.

you need: your question, your hypothesis, materials, the procedure, your observations and a conclusion.
How do you make a homemade thermometer?
this is how to make the easyest homemade thermometer project
what you need: bowl, water, food dye, bottle of drink like coca-cola bottle,
play-doh and a straw.
building step:
step 1: add water into the bowl
step 2: add dye in the bowl of water
step 3: put some play-doh on the bottle hole and make sure that you put your play-doh around the straw and around the bottle hole
step 4: make sure that there is no air and water in the bottle and that the straw is not blocked
step 5: put your bottle part with the water part, but make sure that you don't put water in the bottle because the water will get upper when cold
step 6: put some ice on top of the bottle and wash your red liquid climb up with the ice on top of it.
important note: this project do not work like a normal thermometer because normal thermometer have liquid going up when hot and this project go up when cold, please do not frost the dyed water, only frost the top of the project.
i made this project at school and though to tell it to all of you
