GIVING 98 POINTS, DO NOT ANSWER INCORRECTLY

I am doing a lab experiement on how many drops with the penny hold? With plain water and soapy water.

So what would be the independent variable, dependent varible, and the constant?

I knew that the oil should have less surface tension than the water, but we had equal results – 23 drops for each. Soapy water had the least surface tension. We were only able to get 11 drops of soapy water on the penny.

Independant variable: the results with soapy water, since is not "original", it is what wants to be tested, in comparison to the clear water.

Dependant variable: the results with plain water, since it is our guide in the experiment.

Constant or control variable: the differences between the two.


Hope it helped,
