Investigation Water Lab
Capillary Action: rolled up paper towel
We took a beaker full of blue liquid and placed one end of a rolled up paper towel in a full beaker and one end in an empty beaker.
Water's capillary action is important to plants and trees because it allows trees and plants to have water flow up the plant by having water climb on the walls of the xylem tubes and pulling more water up with it.

Adhesion: graduated cylinder
Water's property of adhesion is important to life because it attaches to the cells and walls of the tubes used to transport water throughout it's systems.

Surface Tension:paper clips on surface.
Water's property of surface tension causes light objects to float due water's hydrogen bonds. And when you add soap to the water it breaks that surface tension and causes the object to sink.

Surface Tension: water on para film
When water is dropped on the para film it beads up and rolls off.

Water Tension/Cohesion: water on a penny.
My penny was able to hold 26 drops of water and it was able to hold that many because of water molecules attraction to one another and that keeps it in a bubble by holding it together.

Evaporation Cooling: water and alcohol
The alcohol feels colder on the skin but the water would take more heat away from your body than the alcohol due to water's high specific heat allowing it to absorb more heat before it evaporates.
