The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
Science proceeds via experiments, and the basic principal of the experiment is that the results of any experiment must be able to be reproduced in any laboratory, any where in the World, at any time (under constant conditions known as STP - standard temperature and pressure).
In a controlled experiment, there is typically one independent variable. This is the variable that researchers manipulate to observe its effect on the dependent variable. Keeping all other variables constant allows for a clear understanding of the relationship between the independent and dependent variables. However, some experiments may include multiple independent variables, but each one must be tested in a controlled manner.
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.
You must wash your hands after an experiment so you don't contaminate yourself with anything harmful.
To ensure results are of optimal percent error, scientists must manipulate only one variable. Therefore, they use controlled experiments.
Experiments provide answers to scientific hypotheses. Experiments must be closely controlled in order to come up with an accurate result.
Controlled variables are things that must be controlled and kept the same during the experiments in order to prevent them from having an impact on results.
Light experiments are conducted in dark rooms to minimize external light interference. This helps in keeping the experiment controlled and accurate, as external light sources could affect the measurements or outcomes of the experiment. By conducting experiments in dark rooms, researchers can better study the behavior of light in a controlled environment.
The number of dependent variables in an experiment varies, but there is often more than one. experiments also have controlled variables are quantities that a scientist wants to remain constant, and he must be observe them as carefully as the dependent variables.
The organism controlled by nervous system must be vertebrate. The organisms without developed nervous system are capable only of vegetative reactions. (See the experiments of Luigi Galvani with the frog's leg.)
They must be repeatable
well, you must have a object that gets put under pressure by pistons or what not.
Yes, controlled experiments can be conducted on living things, such as plants, animals, and humans. Researchers can manipulate variables, apply controls, and observe the outcomes to draw conclusions about cause and effect relationships. Care must be taken to ensure ethical considerations are addressed when working with living subjects.
Vehicles traveling under normal conditions must adhere to the two-second rule.
The scientist must propose an idea and document it with experiments that prove it. The experiments must be repeatable by others and the same result must be obtained by them
