A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
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.
How many variables do you need in a science experiment?
Ideally, an experiment should test only one variable (the independent variable) at a time. If you have two or more variables changing at the same time you have no way of knowing which variable is causing your results.
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.
A controlled experiment is designed to test a single factor called a?
Variable
A controlled experiment allows the scientist to isolate and test what?
to isolate and test single variables
How many variables do you test within one experiment?
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.
How many variables can you test in an experiment?
one
A test of the effect of a single variable by changing it while keeping all other variables the same?
controlled experiment
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).
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

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 variables did Pasteur change in his experiment to test the hypothesis of spontaneous generation?
The shape of the flask!
