Properties of water lab

In this lab that we did, we had 3 parts in this lab.  In all three parts of this lab we used water, for our first blog we used pennies. We used the eye droppers to  see how much water droplets we could fit on one side of the penny. My first score was 35. I did it a second time and i got a 27. After this i cleaned the penny  and  filled the eye dropper with alcohol. When we did this i recorded my score at 25, the second time i did it i got 20.
    Our second lab we did was with string and beakers. we had one beaker full of water with the other one empty. Then our objective was to get the water from one beaker to the other  using a piece of string. First we wet the string so the water could travel on it. Then we stretched out the string and starting pouring the water out into the other one.

Our third lab we had we used water with wax paper and a toothpick. We put a puddle of water on the wax paper and we had to separate the puddle   using a toothpick.
