Question

Describe how you controlled other variables in your investigation so that they affected the results as little
as possible.​

Answer 1

Answer:

Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. Why just one? Well, if you changed more than one variable it would be hard to figure out which change is causing what you observe. one independent variable

You should generally have one independent variable in an experiment. This is because it is the variable you are changing in order to observe the effects it has on the other variables

I hope it helps.

Answer 2

Independent, dependent and control variables. Never heard of them? Well, grab yourself a cuppa, a biscuit or two, and prepare to feel confident enough to teach it to your young scientist standing on your head with a blindfold on! Working scientifically is a key area within the national science curriculum, from primary all the way up to A-level. This area of study concerns skills which relate to practical investigations, for example planning an experiment, carrying it out, writing up conclusions, as well as processing results mathematically. However, identifying variables in scientific investigations can be a cause of much confusion.
