I'm starting out my first night of "fun" learning with a good bit 'o science. Science is my favorite topic so this should make this a bit easier for me and possibly a bit harder on all my imaginary readers. Instead of always calling them my Imaginary Readers I shall give them one single name to define them all. From this day forth my imaginary readers shall be known as Kalpita. I name you all Kalpita because it is an Indian name meaning "imaginary" which i found quite fitting. I'll stop rambling long enough to start talking a bit about what I';m going to learn about today.
Surface Tension
The all-knowing Wikipedia proudly tells me that Surface tension is a property of the surface of a liquid caused by cohesion of like molecules, which is responsible for many of the behaviors of liquids.
In Teenage terms surface tension is basically waters ability to hold itself together and stick to itself. It's like when you put two drops of water next to each other they tend to bond together into a larger drop of water instead of simply bumping up against one another like solids do.
Surface Tension can be measured by counting how many drops of water can be fit on a penny.
Surface Tension only applies to liquids. This should NOT be confused with Surface Energy which we will get to later. Maybe.
To make things funner (for me. not you.) I have a mission
Mission: Find out how soap affects the surface tension of water. At all costs.
Procedure: Count how many drops of soapy water can fit on a penny. Compare this with how many drops of normal water you can fit on a penny
Control: Counting how many drops of regular water can fit on a penny.
Independent Variable(The variable that changes.): Soapy water
Dependent Variable(the variable affected by the IV): How many drops of water can fit on a penny
It's midnight right now and my parents are sleeping. I must manage to go into the bathroom and perform my experiments without waking anyone. This should be pretty easy. I will report to you with my results later. Wish me luck.
