Fleas and Rats - Chaos!

 Basic Body Paragraph - Fleas and Rats

During the black death 75-200 million people, almost one-third of the world’s population causing it to be named the deadliest pandemic in history. The black death started in china and spread wide around the world, mainly getting transported by the trading ports making it harder to contain. During the first year, it hit all of the countries near china and a while after managed to hit Europe. The plague started from the fleas that had the infectious fever caused by the bacterium yersinia pestis. We believe that when the fleas bite these rodents and humans it was helping to spread the disease. This helps link back to my main topic, The black death was the deadliest pandemic in history.

Distillation - Chemistry

Last lesson we learned that the process of evaporation is when a liquid turns into a gas. So we can separate a solution, by evaporating away the solvent to leave a solute (Solid). But what if we want to collect gas? when we trap the gas and turn it back into a liquid this is called condensation. Distillation uses the process of condensation. 

What is -
Evaporation: Heating a liquid, turns to a gas.
Condensation: Cooling down a gas, turn into a liquid.

Set-Up - 

Hypothesis - I think that the water will be evaporated but I don't know what the solid will be.

RESULTS - 

As we turned the orange flame to blue the coke zero inside the conical flask heated up very quickly and was boiling in no time, along with the massive bubbles there was also lots of condensation gathering on the glass. attached to the conical flask was the tube thing wich slowly started pumping small amounts of clear liquid into the test tube that was dumped into a beaker full of ice. Coming out of the test tube was a ongoing stream of smoke. During the 20mins the coke zero slowly went down till there was barely any left, the colour was now almost black kinda like soy sauce but a shade darker. When all the water evaporated from the coke what was left was a small puddle of inky black.
