Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.

What variables did Pasteur change in his experiment to test the hypothesis of spontaneous generation?
The shape of the flask!
What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
How many variables should you have when you test a hypothesis?
there should be atleast 1
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
Are all scientific experiments controlled?
hi my name is Chasity im a freashmen in high school. this is the answer: Control means a factor which remains the same and doesn't change while variable is the other thing which can vary according to situation. hope that helped.
How many variables can you test in an experiment?
one
How do the test variables (independent variables) and outcome variables (dependent variables) in an experiment compare?
The test variable (independent variable) controls the outcome variable (dependent variable).
A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
How many variables does a controlled experiment test?
As many as you need. You can't change more than one if you want accurate results.
What variables did Galileo test when he conducted his pendulum experiment?
he sucked balls and he was gay
A controlled experiment allows the scientist to isolate and test?
a conclusion
How many variables are generally tested in an experiment?
The trick to designing a good experiment is to figure out a way for it to test the effects of only one variable, and to avoid any effects of others.
When a experiment only has one variable that can change and all other variables are kept unchanged this type of experiment is an?
it is a fair test
What is the difference between a test and an experiment?
A test is used to determine the performance, reliability, or function of something, while an experiment is a controlled procedure undertaken to discover, test, or demonstrate something. In a test, variables are usually kept constant, whereas in an experiment, variables are intentionally changed to observe their effect.
What variables did Pasteur change in his experiment to test the hypothesis of spontaneous generation?
The shape of the flask!
How do hypothesis help in doing some experiment?
Because it will perform a test of how two variables might be related. This is when you are doing a real experiment.
What is it called when a scientist is conducting an experiment and and it has factors that can affect the results?
If they are supposed to affect the results in the experiment ie. they are what is being tested, they are the test variables. If they must be kept the same to ensure a fair test ie. the scientist is not testing with them, they are called control variables.
