Our Incredible Atmosphere!

 

Evangelista Torricelli first discovered air pressure in the early 1600s.  Torricelli filled a 1-meter glass tube with mercury.  When he held the tube in a bowl of mercury, the mercury in the tube dropped to 76 centimeters.  Torricelli concluded that the pressure of the air on the mercury in the bowl prevented the mercury in the tube from emptying completely from the tube.

 

During this assignment you will become scientists who have discovered crucial information about the atmosphere, its components and its behavior.  You will research information about the carbon dioxide-oxygen cycle, the nitrogen cycle, and air pressure and air density.  You will use chapter 15, handouts about the carbon dioxide-oxygen cycle and nitrogen cycle, in class demonstrations and out of class materials to compete this assignment.  Your project will consist of an information packet with answered questions, diagrams of cycles, observations of demos with recorded results and answered questions, and handout on uses of atmospheric gases.  Project due date is Thursday January 18, 2007.

 

Note Packet (50 points)

• Using the handouts provided during class, research the information found in the handouts about the carbon dioxide-oxygen cycle and nitrogen cycle
• Create diagrams of the oxygen-carbon dioxide cycle and nitrogen cycle using the handouts.
• During the demonstrations throughout the week you will be responsible for recording your observations and answering the questions provided at those times.
