What is the control on the penny water drops experiments?
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
If one student tossed a chalkboard eraser horizontally so that the eraser hits the ground 5 meters away at exactly the same time another student drops an eraser which eraser hits the ground first why?
They hit at the same time.

How surface tension behaves?
for example, if drops of water are placed on the top of a penny, the surface tension is going to hold the drops on top of the penny. when the penny can hold no more, it will all overflow. make sense?
How many drops can you hold on a penny list one uncontrolled variable?

How many drops of water can fit on a penny research paper?
Alot of drops fit because if you keep the surface tension from moving then you could put as much drops as you can.] ==If you put a penny on a flat surface and keep its tension and keep the penny from moving you can put as much drops as you can till it leaks off. You cant put as much as you want cause the penny will overflow. its not a big object?

Is the variable alcohol when using water and alcohol to see how many drops can fit on a penny?
Yes, in this experiment, the variable "alcohol" refers to the liquid being tested to see how many drops can fit on a penny. By changing the type of alcohol used, you can observe how it affects the number of drops that can fit on the penny due to variations in surface tension and viscosity.
