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 heat proof.
• Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.
• Test tube tongs - These are used to hold a hot test tube after an experiment.
• 
• Spatula - This is for holding very small amounts of chemical powders.
• 
• Funnel - used to channel liquids into a smaller container.
• 
• Measuring Cylinder - This is used to measure liquids for experiments. The liquids will be poured into a beaker or test tube once measured out.

  Hurumanu: The Water Cycle

  
  

  AIM: TO LEARN ABOUT WATER ON EARTH.

  Definition:

  
  

  Scientific words:

  • Evaporation. When water is heated by radiant energy it turns into water vapor.
  • Transpiration. Evaporation from plants.
  • Condensation. When water vapor cools, molecules join together and form clouds.
  • Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
  • Acidification: the action or process of making or becoming acidic.

  Bag 1: Normal Water cycle

  Bag 2: Water cycle with CO2 added: like Oceans in climate change

  Bag 3: Water cycle with ice added: like Antarctica in climate change

  Acidity	3	1

  
  

  Key: Water and acidity amount: 0 = none 

  1 = small 

  2 = large

  ACIDIFICATION  THE OCEAN BECOME MORE WASTED 

  DEFINITION: ITS A BIG WIDE AREA WHEN TREES GETS CUT OF 

  What is happening to the oceans?                                     The ocean contains about 97% of all the water on Earth. The ocean plays a starring role in whatever happens with the environment. One big part of its role is to soak up energy (heat) and distribute it more evenly around the Earth

  
  

  What does this do to shellfish?

  
  

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

Hurumanu - Decomposing and Recycling

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think that......

Materials:

1. banana  
2.   bread 
3.   blastic
4.   cardboard
5.   test tube holder
6.   
7.     

Steps:

1. put the ingredient in each test tube holder     
2.   wait 5 weeks
