Properties of Water!

 The class performed a water lab in groups and I had tons of fun! (: We tested a variety of things as far as: how many droplets of water or alcohol a penny would hold before it spilled, the form water takes when it's placed on a sheet of wax paper, and also how far water can travel down a string without hitting the floor before it gets into the cup.

  • As far as the water on the penny, the highest number one of my group members got was around 35. With the alcohol, the highest number was 27. 
  • Water was placed onto the wax sheet. When we attempted to cut the drop apart with a toothpick, it just moved around the paper. 
  • In order for the water to travel down a long length of string you had to wet it. My group, of course, wanted to break the record (: so we took just over the record holding amount and attempted it! We got water about 3/4 the way down before it spilled onto the floor. Before we had another chance to try again, the bell rang. BUT, we were suprised at how far the water actually did travel without hitting the ground. 
After the lab, we did research for some reasons why the water molecules acted the way they did during the lab... & here's what i learned!
