Is A Marble Of Glass More Heavier Than Water

it depends because u need to know the weight first to know witch one is heavier but an object float's when they are less dense than the liquid that they are placed into and the glass marble always sinks so the glass on it most be more dense than the liquid and also an object that is more dense can float due to the surface tension if that can help in anyway but u need the to know the weight to really know I guess

i believe the answer is:   psychological  experiment

in this experiment, wilhelm wundt became the first person that implement scientific method in analyzing the pyschological phenomenon.

due to this result, wilhelm wundt also able to make psychology to be acknowledged as a separate scientific field from biology.

well, there are a lot of places we get information about earth from. like science classes, websites, books, newspapers, etc.
