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.

Oceanography

   At this point im going to be honest, im still a little confused about the ocean.  I do understand how important the ocean is for the rest of the world and for our survival.  We are as far we know one of the only planets with water and that is very unique.  I cant wait to learn more about it this year because right now i am not very knowledgeable.
   many find an escape in the ocean and i think that further than than science can prove the ocean has amazing effects on people as far healing and rejuvenating.  Many people go there just to escape from everyday life and surf and free their minds.

Week one do now reflection

   So far into the 2013 school year i have learned a lot and had a lot of fun doing it.  What i like about physical science so far is that it incorporates  math and is more exact than a guess.  I find the labs very interesting and the outcomes weird, yet i learn a lot at the same time.  For example, the bowling ball lab; i had no idea a bowling ball couple float in fresh water, or why.  Now i understand that the density controls the outcome of weather the ball is goings to stay floating or sink.

   the other part of Physical Science that i like is the Do Nows.  They get me thinking before class.  It kind of wakes me up and prepares me for the class .

          

Oceanography is a very interesting topic to me because I love learning about the ocean.  I find creatures that live in the water very cool.  I am very excited to learn about how the ocean effects the world in all different way.  I've also heard the moon has a lot of control over the ocean and the way it sways and its calm.  I do not know much about oceanography but I am looking forward to learning about it throughout the year!
