Science class X Experimental projects [1], also known as investigatory projects, start with a question (AKA a hypothesis), use the scientific method to complete the research, and end with a report detailing the results and conclusions and an abstract.
The hypothesis of Andreas Cellarius, showing the planetary motions in eccentric and epicyclical orbits. A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. A scientific hypothesis must be based on observations and make a testable and reproducible prediction about reality, in a process beginning with an educated guess or ...
A warm little pond is a hypothetical terrestrial shallow water environment on early Earth under which the origin of life could have occurred. The term was originally coined by Charles Darwin in an 1871 letter to his friend Joseph Dalton Hooker.
This hypothesis was much criticized, as turbulence is a phenomenon associated with disorder and would not spontaneously produce the highly ordered structure required by the hypothesis. It also does not provide a solution to the angular momentum problem or explain lunar formation and other very basic characteristics of the Solar System. [5]
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one ...
Out of Asia theory of human origin – The majority view is of a recent African origin of modern humans, although a multiregional origin of modern humans hypothesis has much support (which incorporates past evidence of Asian origins).

The concept is also referred to using the German-language term Gedankenexperiment within the work of the physicist Ernst Mach [ 2 ] and includes thoughts about what may have occurred ...
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
