Feb 10 - Water

The Agenda for February 10 th was:


As you can see above, we talked about how the water currents affect people.
We came up with how the water currents help with the transportation of shipments and the fishing of fish, and other marine animals.

Next, in this link, you can read about what happens when high voltage electricity goes through water.


The images above shows how saltwater molecules are reacting faster then the fresh water.


These pictures are all things that we did in class.

Water, Water, Everywhere!






















1.  We focused on how the ocean currents had warm areas and other cold ones, and we revised our maps.


  • Red represents the warm parts


  • Blue represents the cold parts

We learned that;

  • Warn water --> Raises
  • Cold water  --> Sinks
  • The southern currents are warmer because they come from near the equator.










 We also discussed the different temperatures due to the currents. And we found out that it all depends in the place you are in because some parts of the currents are cold and some are warm.










2.  We saw an example of how water could be broken apart
And we also saw how water pumps worked.

Water goes into the motor ran by electricity then the motor builds pressure inside and shoots out the water.

  1. After introduced to the schedule we moved on to a reviewing question from last class:

- How does the water currents affect people?
- We answered,  temperature.






2.  After having heard answers we moved on to our question and demo of the day:

-What happens when high voltage electricity goes through water?
-How do water pumps work? 

-The answer was,''Energy is stored in the bonds of molecules. When these bonds split apart, the energy released can be used to do work. Breaking apart liquid water molecules into hydrogen and oxygen gas creates an enormous amount of energy, which can be turned into useful electricity to power our homes and cars.''  states http://www.education.com/science-fair/article/water-electrolysis/

- For the second demo, Mr. Pro answered that in the pump there is a fan that creates pressure that pumps the water. 



Finally, we studied and prepared for both the science fair and the science test that will  be on wednesday, February 13 2014

1. After introducing the schedule, we moved on to reviewing what we learned last class. 
                             - We went over the vocab words that we learned last class (porosity, permeability,        water table). 
                             - We answered why groundwater was important.

        
    2.    a. After going over that, people volenteered to write on the board something they know about the ocean. 
           Basic knowledge:
               

  1. Names of the oceans:


  1. Atlantic
  2. Pacific
  3. Indian
  4. Arctic
  5. Southern (Antarctica)

  1. Names of the big seas.
    1. Mediterranean
    2. Caribbean
    3. Smaller Ones: Black, Dead, Red, Japan



The next thig that we did in class was 2 tasks:





  1. Find an area as big as you can in your task book.
    1. Use a pencil to start.
    2. Once it looks alright, darken the pencil or go over it in pen.
    3. Just a rough sketch is enough.


  1. Label the oceans: Atlantic, Pacific, Indian, Arctic and Southern


Pictures of student drawings:





Task #2: Based upon clues predict the following global circular surface ocean currents.
Use simple arrows to show the direction and path of the ocean currents.
The major surface currents are circular.



             After drawing, we made a experiment to see how the ocean moves, and we also talked about the global ocean currents. We also saw a digital version of the wind currents around the world.

What would we do witout water!?

Agenda 

  1. What did we learn about ocean currents?
    1. Check out the scribe post.
  2. Demos
    1. How can break apart water?
    2. How do water pumps work?
  3. Study for your test (15 mins)
  4. Science Fair Information
    1. Start bringing in your materials if you are collecting data during class-time.
    2. There’s a copy of this document in your Science folder to guide your Science Fair Project.  

Currents




We revised the ocean surface currents and compared different places in the world to see which costs are cooler and hotter. We made analisis to see which parts of earth were hotter and which were colder.

Demos

  1. How can break apart water?




  1. How do water pumps work?
We revised pressure and how it makes water pump. We said why a pump might be important and for what we could use it.

Study for your test (15 min)

We had time to study for our test using Quizlet flashcards and scatter. We revised D, C, B and A questions for this unit. Here some examples of questions: 

D) Write down at least one reason why water is important.

c) Write down an example of a property of water that can be measured. Write down the units for the measurement.


B) Explain two reasons why the water cycle is important to society.


A) Humans are affecting the water cycle. Hypothesize another way in which humans are affecting the water cycle and what the effects are. (3 - 1 for an effect + 2 for explanation)


Science Fair

People worked on their science fair project until the end of class. 

Mr. Pro had boxes that people could use.
People also made research during that time that could help them in their project.
Mr. Pro answered questions people had about their project.

Here is a document to guide your Science Fair Project.  


Oceans: A world full of currents


 5.2.14 Today's Subject: Oceans

 Basic Knowledge:

  • Oceans provide about 30% of our protein.  It’s salty.  It’s saltwater.You can’t drink it.The ocean is about ~70 % of the Earth’s surface.There are many currents.There are many types of plants and animals.It’s always moving. Sometimes, sewage and garbage is dumped into the ocean.

1. Names of oceans
  • Atlantic
  • Pacific
  • Indian
  • Arctic
  • Southern (Antarctic)
2. Names of big seas
  • Mediterranean 
  • Caribbean


 

The way water moves:

Temperature:



  • Water heats up at the equator and stays on the surface. It flows to cooler regions.
  • Water cools at the poles and sinks (because cool water is denser) and flows to warmer regions.
Red died water warmer and that is why it is on top. The lamp represents the sun which warms up the water with the red die which is less dense than the cooler water that has blue die and is at the bottom.

Sketch: World 



Global Winds:



2) Global Winds
Winds are the main source of movement for surface ocean currents.  Wind passing over ocean, through friction, causes the ocean to move.
 
Atlantic

 


Pacific



Indian

 

Southern

 


Arctic





Coriolis Effect:



  • The Earth spins on its axis.  Fluids (the atmosphere and the oceans) will be deflected by its spin.  
  • Currents in the northern hemisphere tend to move clockwise.
  • Currents in the Southern Hemisphere tend to move counterclockwise.

Current:


4) Surface Currents
  • The animation is a summary of satellite data from NASA tracking all the surface currents.  This video shows the details of all the currents.  Look at the patterns to try to figure out the global currents.
Video of NASA: Perpetual Ocean



  • North Atlantic, clockwise
  • South Atlantic, counterclockwise
  • Indian, counterclockwise
  • North Pacific, clockwise
  • South Pacific, counterclockwise
  • Antarctic Circumpolar, clockwise
