9/11

Hey today we will be talking about something very sad 9/11. I'm sure allot of us know what 9/11 is all of us were alive when it happened. Well what happened is that 4 planes were hijacked two of them flew into the twin towers the first plane hit the north tower at 8:45 a.m. the second one hit at 9:03 a.m

 At 9:37 a.m. the third plane crashed into the pentagon then at 10:03 a.m. the fourth plane crashes into a field in Pennsylvania.

Since 9/11 we've been way more cautious and have way tighter airport security. I think in the future people will look back at this and remember all the people that died and how we fought. There aren't many good things about 9/11 but one of the best things about it is that when it happened we all came together.

Democritus Vs. Aristotle

Democritus

Democritus was a Greek philosopher who started research on atoms and matter 2400 years ago. His theory was matter could not be divided forever eventually you would be at the smallest piece possible. And his theory was ignored for 2000 years because of Aristotle's theory.

This is what they thought the atom looked like

Aristotle

Aristotle believed in the four elements. Earth, water, fire, and air and he  showed this by burning a log. The log is earth the fire is fire and the smoke is air and he put the fire out with water. And the people back then believed him because  it was easier to understand and they could see it with there own eyes.
