Water Property

Joe and I had the water property  buoyancy. For our demonstration, we placed and egg in a cup that was halfway full of water. We let the egg sink to the bottom to show how the egg didn't have much buoyancy. Then we took the egg out and put slat in the water and stirred it until all the salt was dissolved. Then we placed the egg back into the water. As a result of the added salt, the egg's buoyancy increased as the water's density increased, allowing it to float with more ease.


Luckily, everything went as planned during our demonstration because we planned it out carefully.
Five thing I learned during everyone's presentation included
  • Turbidity is how cloudy the water is
  • Water helps mediate the extreme weather changes by having a high specific heat, allowing marine organisms can adjust more easily
  • If there's not enough porosity, plants won't be able to get enough air to grow naturally
  • Salt water conducts water better than distilled water because of the higher concentration of minerals in salt water
  • pH stands for the power of hydrogen
