Using hypothetico-deductive reasoning is following a scientific process of forming various hypotheses about a topic, choosing one of these hypotheses to test, making predictions based on the chosen hypothesis, testing the correctness of the hypothesis through experimentation and observation, and then concluding whether the hypothesis is confirmed. The beginning of the process involves looking for a new problem that hasn't yet been explained by others.
Hypothetico-deductive reasoning can be used to solve problems ion such fields as chemistry and biology. When making predictions, the experimenter deduces what could result from observation or experimentation.
In addition to being used in science, this type of reasoning can be helpful for everyday life problems. For example, a person having problems with a music player not turning on may hypothesize that a battery replacement is needed and that the player will turn on after the battery has been replaced. After the person replaced the battery and the player switches on, the experimenter can conclude that his or her hypothesis was correct.Learn More
In 1803, John Dalton developed a hypothesis that atoms are a type of solid sphere. He has four primary statements in his theory, including that atoms are responsible for making up all matter, that atoms join to form compounds, that within the same mass, all atoms are identical and that atoms are indivisible.Full Answer >
Limewater can be used to detect the presence of carbon dioxide, or CO2. When air containing CO2 is blown directly into the limewater, it forms calcium carbonate. This turns the liquid cloudy, showing that the gas is present.Full Answer >
Starch would not give a positive Fehling's test. This test is used for testing the presence of sugars, such as fructose, glucose and maltose, with the exception of sucrose.Full Answer >
A Benedict’s test is used to determine the presence of reducing sugars such as fructose, glucose, maltose and lactose. It is also used to test for the presence of glucose in urine.Full Answer >
