My Investigation on climate change

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.

THE WATER CYCLE SONG

THE WATER CYCLE EXPERIMENT

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

Material:

1.  1 vivid
2.  Zip lock bag
3.  Double sided tape
4.   Half a cup of warm water
5. 2 drops of blue food colouring
6.  Scissors

Steps:

1.  Draw the water cycle onto the zip lock bag with the vivid marker.
2.  put one and a half of warm water into a cup.
3.  put the water inside the zip lock bag.
4.  put two drops of blue food colouring into the water that's inside the zip lock bag 
5. hang it up on to a window

Two Images:

Findings:

	The Water Cycle	Acid Water Cycle
Does it cycle?	2	1
Amount of Water	2	2
Acidity	1	2

Key: Water and acidity amount: 0 = none 

1 = small 

2 = large 

Other comments:

Conclusion: I really enjoyed making the zip lock bag, I was really surprised that it actually worked. It didn't really take too long to do it, It is a really easy and fun thing to do at home when your bored, it also contains some household products so you can definitely make your own at home. I also learnt a few things while doing this hurumanu like,I learnt how to make the water cycle out of a zip lock bag and leaning how the water cycle works. 

My Investigation on climate change

ACIDIFICATION

DEFINITION: When there is a significant CHANGE to the chemistry of the ocean.

What is happening to the oceans?

some of the co2 (carbon dioxide) comes from burning things and it makes the carbon dioxide which then goes into the air which eventually goes to the ocean and makes the ocean more acidic.

What does this do to shellfish?

It affect the shellfish because when the carbon dioxide get into the water it dissolves in it and makes  acid, this can affect them by preventing them from making shells.

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

As humans burn more fossil fuels, The carbon dioxide in our atmosphere rises more and more.
Making air and sea hotter and hotter.

DEFORESTATION

DEFINITION: CLEARING AN AREA WHERE TREES ARE.

What are trees used for?

It affects the climate because when the trees are cut off the clouds cant produce rain because the moisture from the plants and trees can make the rain and if the trees are gone some of the rain will also be gone, there will be nothing to absorb the rain.

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

It relesases greenhouse gasses including carbon dioxide into the atmosphere.

ICE CAP MELT

DEFINITION: WHEN THE ICE MELTS SEA LEVELS GO UP

If all the ice melted what would happen?

If all of the ice melted ocean levels would rise up to 70 meters high.

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?

When the Ice melt it uncovers a darker land or ocean beneath it, which then when it is uncovered ocean or land beneath absorbs more sunlight which causes more heating.

WATER VAPOUR

DEFINITION: Water vapour is an evaporation or boiling of liquid   it can also come from sublimation(sublimation means when something solid turns to gas without going through a liquid stage.) of ice,unlike any other forms of water, water vapour is INvisible.

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

 Water evaporates from the land and the sea, Which then eventually comes back to earth as rand and snow.
