States of Water/Matter

Posted by Ruel Apostol on 12/5/2019

Hello Huskies!

We are currentl on Unit 1.3 States of Water.  We are going to be learning about the following:

  • Explain the macroscopic properties of solids, liquids and gases using the particle model of matter.
  • Relate observations regarding the addition of energy by warming to increased particle motion.
  • Observe and explain that energy can be transferred into a liquid from warmer surroundings, causing its particles to speed up and break away to become a gas (evaporation).
  • Observe and explain that when gas particles transfer their energy to cooler surroundings, they may slow down enough that their attraction to one another causes them to become a liquid (condensation).
  • Observe and explain that when the particles of a liquid transfer their energy to something cooler, they slow down enough that their attractions cause them to arrange themselves into fixed positions as a solid (freezing).
  • Observe and explain that when the particles of a solid speed up enough that the motion overcomes their attraction to one another, the particles can move past each other to become a liquid (melting).

We are in the process of concluding Activity 1 - "Heating Up".  We are learning how heat is being transferred from one material to another.
