Why do scientists use density calculations to determine the kind of substance with which they are dealing?
so that they can have a better chance of finding the mass
When performing an experiment is it possible to test more than one variable?
In general it's better to only change one variable at a time. This may not be practical depending on exactly what you're working on. Astronomers, for example, can't just go change a star's mass and see what happens; they have to work with the data they can get. Dealing with more than one variable complicates matters, but may be possible if you've got a good grasp on the underlying theory (or at least a good working hypothesis) and take enough measurements; you'll wind up solving a system of simultaneous equations, which is a lot more complicated.
What is a madubla oblengoda?

Why is it important to control all variables exempt one?
That is simply not true.There are times when a number of factors can have an effect on the outcome of an experiment but it is not possible to conduct the experiment so that only one factor is allowed to vary while all others are controlled. It is far more efficient - in terms of experimental units - to design the experiment so that the interactions between variable factors can be estimated. Experimental design is the subject that deals with the problem of designing efficient schema for dealing with a number of interacting factors. You may wish to look at "Latin square design" and "Greco-Latin squares" as an introduction to design.

Can you control speed?

What is a independent varible?
An independent variable is the part of an experiment that you control. You can change it and make it anything. Such as an experiment dealing with the length of time it takes certain brands of chewing gum take to lose their flavor. The independent variable would be the brands of gum you decide to test, while the dependent variable would be the time it takes those brands to lose their flavor.

In scientific research What is the control?
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.the control is what you don't change in the experiment.Example: if i poured water on certain tapes (like duct tape and scotch tape) to see which one was the stickiest. My control would be how much water I poured on the tape. there can be more than one control and in this example the other two controls would be the length and the width of the tape.
