Sounding the sea

This activity required knowledge of the sea floor.  We have to understand that the seafloor is always changing and continualy changes so we will never get one measurment that will last forever.  The abyssal plain is the smoothest and least explored region in the world.  The underwater seamout, is basically a underwater mountain.

Flame Test lab

During the flame test lab there were some slight inaccuracies.  If there was too much oxygen running into the gas, the fame would be to big, to little would make it to small.  It was difficult to know which substances were unknown because they all had a reaction to the flame.  Identification of a substance with only one property is valid because we know exactly what is in the specific substance.  The flame turns color when one electron is pushed from one orbital to another.  The metallic elements used in the activity were

• Kn03 - Potassium  
• Sr(n03) - Sulphur
• BaN03 - Boron
• CuC12 - Copper
• LiN03 - Lithium
• CoCO - Cobalt

To heat up the reactants in the metal causing them to react by changing color.

Video and article

In the video, the man starts off talking about how the universe was created.  This is a very controversial topic.  While science and religion do not mix, there is no definite answer as to how exactly the world was started.  We can however take very educated geusses/answers more or less.  16 billion years ago everything had been compresed inside of one small atom.  the energy inside that one atom was so dense and powerfull, that it exploded and created what we know as our universe.
