What controlled variables in science?
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.
What are the basic principles of scientific approach?
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).
Why do scientists repeat experiments?
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.
Why must we wash our hands after experiments?
You must wash your hands after an experiment so you don't contaminate yourself with anything harmful.
Why do you have to wear goggles in science experiments?
You must wear goggles in science experiments in case a mishap resulted in your eyes being sprayed and you eye-sight may be damaged.
Why do scientists use the data from controlled experiments?
To ensure results are of optimal percent error, scientists must manipulate only one variable. Therefore, they use controlled experiments.
Can fertilisers come under toxic chemicals?
Fertilisers are not toxic products; but, of course, fertilizers must be used only rationally and in controlled conditions.
Investigatory project in Chemistry?
Experiments provide answers to scientific hypotheses. Experiments must be closely controlled in order to come up with an accurate result.
What is the group that experiences no changes in the independent variable?
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.
Why it is important to use the same amount of saliva and starch solution in experiments?
So results are valid all controlled factors must be the same.
What are traits of an organism controlled by nervous system?
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.)
What controlled variables in science?

What must Experiments and investigations must be?
They must be repeatable
What conditions must be met to compress gas?
well, you must have a object that gets put under pressure by pistons or what not.
What makes a scientist right?
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
What are the basic principles of scientific approach?

How do experiments help scientists learn abut the world?
Experiments helps scientist test the ideas. Experiment is simply an act of performing a controlled test about an idea. Before an experiment is made, observations using senses must be deduced from the environment at first. Observations leads to the formulation of hypothesis.
