Station #1:
Which feels cooler? I think that alcohol is much cooler.
In order to get rid of excess heat when you sweat. The sweat absorbs heat and evaporates away- taking with heat energy. Why is it beneficial that your sweat is water not alcohol based? I think because that alcohol vaporized in lower temperature and water has higher boiling point so that way water absorb more heat.

Station #2:
How many drops fit on the penny? How was your penny able to hold that many drops? 24 drops. Penny able to hold all that drops from cohesion and adhesion.

Station #3: The parafilm didn't absorbed any of the water because of surface tension.
Station #4:
How many you can get to float before they sink? - Three. If you add dish soap to the water, it will break the (hydrogen bonds) water and make the paper clips fall down.

Station #5:
Why the water line is not not straight line across in glass container? Because of adhesion.
Why the water property of adhesion be important in living system? Because when the sweat stuck to your skin because of adhesion, it cools you off.

Station #6:
Why would capillary action be important to plants and trees? Because tree and plant have to transfer the water from the ground from its root in order to survive.
