Hi this is my blog about the 4 things I learned from the past weeks of term one.
Convection; convection is the area of liquids or gasses with more thermal energy in their particles that will rise, while areas with less thermal energy will fall.
Contraction: Contraction is when the particles vibrate slower and move close together when thermal energy is removed, causing solids, liquids and gasses to contract ( get smaller ) when cooled.
Diffusion: diffusion is when the particles move from areas of high concentration to areas of low concentration until they spread out evenly.
Conduction : conduction is the transfer of heat or electricity directly through a material, usually solids.
Key Learning :
CONVECTION: Convection is the thing that transfers heat by the physical movement of fluids. When the fluid is heated it becomes less dense, and like when it rises and cools down.
This convection experiment with my group mates went great. We had fun doing that drop crystal on the liquid water inside a beaker, it was very satisfying watching it.
CONTRACTION: Contraction is thermal contraction is the decrease in a material’s volume, or like shrinkage when the temperature decreases, and like how the particles lose kinetic energy, it starts to slow down and pack more closely all together.
The convection experiment was my favorite because the pooping sound is so satisfying to hear and the way it shrink so fast was so good , but sadly mine wasn’t hot enough to shrink and make a loud pooping sound but it’s okay it was fun to watch anyways.
DIFFUSION: Diffusion is the passive movement of particles from the higher area of concentration to the lower concentration until it is heavily distributed to all the parts.
The diffusion experiment was very interesting because we got all perfect like a beautiful droplet slowly spread out and the color was so pretty.
CONDUCTION: Conduction is the transfer of heat through the solid matter directed to the moleculars collision.
The conduction experiment was probably my least favorite because it was kinda boring and the pin took so long to fall it took as nearly fifteen minutes for one pin to fall and there were six pins so we didn’t get to finish the experiment because we were running out of time.
