Diffusion

Diffusion: Diffusion is the movement of a substance from an area of high construction to the area of low construction.


Aim: To observe diffusion in a liquid.


Equipment: Petri dish, water, tweezers, a crystal of potassium permanganate.


Method: 

1. Half fill your petri dish with cold tap water.
2. Place the petri dish on your workbench and allow the water to become settled.
3. Using the tweezers, place a single crystal of potassium permanganate in the center of the petri dish.
4. observe for 5 minutes.
5. Repeat the experiment using hot water.

Result:

In cold water: Diffused slower 

In warm water: Diffused faster 


Discussion: hot diffused faster and heat of the water made the particles break apart faster, and because cold is thicker it made the particles break apart slower.

photo montage

 Hi everyone today we did photo montage in Art class and we looked at some of Hannah Hochs arts and then this is what I did, first I cut out photographs and then I resembled it, and then I used 4 different images to do this and this is how it looks like hope you like it.

Thanks, have a good day.

Matter

Matter:

The matter is almost everything around you, everything that has mass or takes space is matter.

the different state of matter:

solid: particles are not moving 

Liquid: particles move not to fast 

Gas: Particles move quickly. 

Solid to liquid:  melting 

gas to liquid: condence

Mount Vesuvius erupts, city abandoned for years

WHAT HAPPENED………. On August 24, after centuries of dormancy. Mount Vesusive erupts in southern Italy, devastating the prosperous Roman cities of Pompeii and Herculaneum and killing thousands. The cities, buried under a thick layer of volcanic material and mud, were never rebuilt and largely forgotten in the course of history. 2000 people died in this and the city was abandoned for many years.  shrouded the city in “darkness…like the black of closed and unlighted rooms.” Two thousand people died, and the city was abandoned for almost as many years.

\WHO WAS INVOLVED (INTERVIEWS) Pliny the Younger, a Roman historian who witnessed the 79 AD eruption, write the oldest surviving description of the tall, tree-shaped, cloud that rose above the volcano, said, “On 24 August, in the early afternoon, my mother drew [my uncle's] attention to a cloud of unusual size and appearance. Its general appearance can be best expressed as being like an umbrella pine, for it rose to a great height on a sort of trunk and then split off into branches, I imagine because it was thrust upwards by the first blast and then left unsupported as the pressure subsided, or else it was borne down by its own weight so that it spread out and gradually dispersed. Sometimes it looked white, sometimes blotched and dirty, according to the amount of soil and ashes it carried with it."
