Hurumanu - Investigation on Climate Change...

My Investigation on climate change


    ACIDIFICATION

    DEFINITION: The action or process of making or acidic.

    What is happening to the oceans?
    The oceans are absorbing the CO2, But it does take away the CO2 and that is a good thing but...

    What does this do to shellfish?
    The shellfish in the ocean, where the CO2 gets absorbed, they don't grow as they are supposed to or they are growing at a slower rate every year.

    HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS?

    DEFORESTATION

    DEFINITION: It is a wide clearing of trees in an area.

    What are trees used for?
    Trees help us breathe and to control the weather as well...
    As for us humans breath in oxygen, we exhale carbon dioxide, so the trees take away the Carbon dioxide to make the weathers a little bit better. 

    HOW DOES DEFORESTATION AFFECT THE CLIMATE?

    ICECAP MELT

    DEFINITION: The melting of the polar ice caps is caused by the overall increase in global temperature, and this melting can have serious consequences for all organisms on Earth. As the polar ice caps melt, sea levels rise and the oceans become less saline.

    If all the ice melted what would happen?
    The sea levels would rise and close coast citys would be underwater...

    WATER VAPOUR

    DEFINITION: a dispersion, in air, of molecules of water, especially as produced by evaporation at ambient temperatures rather than by boiling.

    HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

    The Vapour and water contribute by making vapor to form clouds but...
    if there aren't enough clouds or if there are too much, they could mess up the weather,

    Hurumanu - New Science laboratory...

    Aim: To learn about the expected behavior in a science laboratory.


    Our R9 Class Treaty
    1.    Bags under desks,
    2.    No Food or Drink,
    3.   No Running,
    4.   Don't touch experiment,
    5.  Report any breakages or spills,
    6.   Do not taste or sniff,
    Safety in a laboratory.

    teacher   shoes   practical  teacher laboratory   ask  sniff teacher  breakages 
    1.   Follow the instructions given to you by the Teacher.
    2.   You must not enter the laboratory without your teacher.
    3.   Report all breakages to your teacher.
    4.   You must never eat or drink in a laboratory.
    5.   Shoes must be worn at all times.
    6.   If you spill something you should tell your teacher immediately.
    7.  You should wash your hands after every practical activity.
    8. You should know what you are doing. If in doubt ask your teacher.
    9. Never taste or sniff chemicals.
    In your group, discuss how the following scenarios could be dangerous.
    1. Not putting your bag under your desk.
    2. Running around in the laboratory.
    3. Not wearing shoes in a laboratory.
    4. Shaking a test tube with your thumb over its mouth?
    How do we work in this laboratory?
    1. Beginning and End of class: Lining up, Entry, Seating, 
    2. Equipment tray: equipment list and details.
    • Test tube - This is used for experiments using liquids. They have a bung that can be placed in the top. Test tubes sit in a test tube rack.

    • Conical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heatproof.

    • Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.

    • Image result for glass stirring rod
    • Test tube tongs - These are used to hold a hot test tube after an experiment.

    • Image result for test tube tongs
    • Spatula - This is for holding very small amounts of chemical powders.

    • Funnel - used to channel liquids into a smaller container.

    • Image result for funnel
    • Measuring Cylinder - This is used to measure liquids for experiments. The liquids will be poured into a beaker or test tube once measured out.
