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.

Mixing and Dissolving - Chemicals and Chaos

9/11 - Timeline

 Today in chemicals and chaos we all had gotten to do some individual work and choose which assignment we wanted to do. I chose to work on 9/11 because, to be honest, I have never heard of it. I did a lot of research about it and learned a lot about some countries. My task was to make a timeline following the events that lead up to the crash of flight 11 and flight 175. Here is my timeline.

6:00am - Polling station opens
7:59am - Flight boards 11 crew members, 76 passengers, 5 highjackers
8:15am - The flight takes off from Boston to Los Angeles
8:19am - Flight crew informs ground personal about highjackers.
8:46am - Flight 11 crashes into floors 93-99 of the north tower
9:00am - Flight attendant aboard flight 175 alerts air traffic control that a highjacking is underway
9:03am - FLight 175 crashes into floors 77-85 of the south tower.
