Properties of Water
Penny Experiment
In this lab we used a pipette to fill a penny and see how many droplets it took for the bubble to break.
Water property tested
In the penny lab the property of water that we had tested was surface. We know this because the bubble did not immediately break but let in the other water droplets
Cohesion is water molecules sticking to other water molecules. We know this was tested because the bubble that was on the penny could only have held together because this property of water.
The last property we proved was tested was abhesion. We know that this is a property of water that was tested because the water stuck to the penny and didn't just roll of.
Wax paper Experiment
In this experiment we made a water bubble on a piece of wax paper and tried to cut it in a half using a tooth pick
the water bubble did not separate it did not cut.
The main property that was tested was surface tension. The fact that the tooth pick couldn't cut through the water bubble and separate it into two bubbles proves that water has very low surface tension.
String Experiment
In the string experiment our goal was to get water from one end of the string to the other end and into the beaker in this experiment we won the challenge with a 22ft long string.
Property tested
In this experiment the main property that was tested was abhesion this is the property that allows water to stick to another object which in in this case happened to be the string
In Nature
In nature the properties of water are what allows plants to get water to there leaves and branches. Adhesion is what gets the water to the roots and keeps it on the tree and cohesion is how the water travels it sticks to each other and pulls one another through.
