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.

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?
How do water drops hold on to the penny?
Water molecules stick together because of the electrical charges in the water create a bond.
Drops of water on a cold can are?
condensation
Consider drops of water that leak from a dripping faucet As the drops fall they?
get farther apart
How many drops of water is equal to one liter?
"Drops" come in many different sizes (the biggest raindrops have as much water as a thousand of the smallest raindrops and the smallest raindrops are a million times as massive as the typical cloud or fog droplet). However, some old cookbooks reckon that there are 72 drops to a teaspoon and there are roughly 200 teaspoons to the liter, so 14,400 drops per liter is a pretty close answer. You could call it 15,000 and not be far wrong.
What is the control and independent and dependent variable in the 'how many drops of H2O can fit on a penny'?
The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.

how many drops of water can a penny hold? topic: crazy penny........
What property of water allowes so many drops of water to stay on a penny?
adhesion
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?
If you were to put little drops of water on a Penny how many would fit on it?

Why do you use a water bath in chemical experiments?
to control temperatures.
How many drops of water can a penny hold on its surface?
Water has a surface tension. When dropping water on a penny, people usually underestimate how much water the surface of a penny can hold. The surface tension of water is strong on a smaller surface, and when dropping water on the surface of a penny, towards 20 drops the water on the penny will look like it is bulging out a lot. It really depends, depending on which side of the penny you are using, it ranges from 6 to even 34 drops using a simple eyedropper. Because eyedroppers do not produce the exact same size of drops every time, the result is not very accurate. To be even more accurate, scientists use accurate distributing machines and a very new penny to determine how many drops of water it can hold without vibrations. There could be certain amounts of grime and dirt on a penny, depending on how old it is, which can affect how much water can be put onto it. Different types of water can also change how much a penny can hold. Tap water has certain amounts of chemicals in it, and that could also affect the weight and surface tension of the water on the penny. The height of which the water comes off from matters too, the more force of the water that comes down, the more likely the water on the penny is to splash and spill. The place the water lands on also has an effect on it. To be even more accurate, light has a mass. If light shines directly at the water on a penny, it could push it a tiny bit. This change is impossible to see, and it has basically no effect on the penny or water at all whatsoever. Remember, all tests may not be 100% accurate, and there may always be a chance that there is a better way to make a penny hold more droplets of water than the presumed "most advanced and accurate" way.
How many drops of water can fit on a US penny?
One large drop of rain, or as many as 20 average-sized drops of water from an eyedropper, given maximum surface tension. As many as 35 of the smallest drops can hold together atop the coin.
What is the world record for most water drops on a penny?
473
Why is water a good control in experiments?
Simply because it's stable, and it's pH neutral.
