Station 1
In this station we had to test which feels colder. Alcohol or water. Well, in order to get rid of excess heat you sweat. The sweat acts as water to cool your body down from whatever you were just doing. The sweat then absorbs the heat and it evaporates. The end result was that the alcohol was colder than the water.

Station 2
Here in this station we will be testing how many drops of water can go on to the penny without it overflowing. If you have the right amount of drops on it then there will be a bubble sitting right on top of the penny. Before the experiment I predicted that it would take only four drops of water before it overflowed. It turned out being twenty one drops instead.

Station 3
Station three: This time we will be experimenting what water will do if we put it on wax paper. Keep in mind that the wax paper is very smooth and slippery. You can test this with water, corn syrup, or alcohol but in this lab we used only water. After putting drops of water on the paper the water slips right off the wax paper.

Station 4
In this experiment we tested how many paper clips we could make float at the surface of the water. You will need to get a cup and fill it with water first. Then get a bunch of paper clips and place them in very slowly and carefully. Next see how many you can put in without them sinking. You may get different answers each time. The amount that me and my partner could do before they sunk was only two but i have seen people that have done a lot.

Station 5
This station will be about adhesion. You will need a meniscus (a graduated cylinder) to repeat this experiment.
When you fill the water up the water line may not be straight. That's because the water sticks to the side of the glass. The water would have to make its way down to the surface but not all of it will fall down. One of the questions was why water property of adhesion would be important in living systems. The water property of adhesion is important in living systems because the water sticks to the glass due to adhesion.

Station 6
This is the last test we did in class. It is about capillary action. You will need two cups, one with water and one without water. Then you will need to put food dye in the water and roll up a long sheet of paper towel. After you roll the paper towel you put one side of the towel on the water side and the other in the empty part. You will see your result in a couple of days. Well, after one or two days of waiting your result has come. The colored water should have been all the way across to the other side. That is called capillary action.
