He put gravy in a flask and boiled it and let it sit for a couple days to see if anything was living in it and there was small micro organisms inside. He said this proved his theory of spontaneous living.
A controlled experiment.
In Needham's experiment, the variables included the presence or absence of microorganisms, the method of heating used (whether the samples were boiled or not), and the type of sealed containers used to hold the broth. These variables were important to understand the effects of heat treatment and the role of microorganisms in the spontaneous generation of life.
A controlled experiment.
A controlled experiment. In a controlled experiment, one variable (independent variable) is changed or manipulated while all other variables are kept constant to observe the effect on the dependent variable. This allows researchers to determine the specific impact of the variable being tested.
The controlled variable for an electromagnetic experiment is the variable that is kept constant and unchanged throughout the experiment. This ensures that any changes in the results are due to the manipulation of the independent variable and not other factors.

A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
a controlled group is like an idea but an experiment that is controlled cannot be changed.
A controlled experiment is an experiment where there are limited or no variables other than the one you are testing for.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
