Hurumanu - The Water Cycle

               AIM: TO LOOK AT THE WATER CYCLE AND HOW                         CLIMATE CHANGE IS AFFECTING IT.


Definition:

A green box with icons and white text. Text reads: Where is Earth's Water? 96.5 percent is in the oceans; 1.7 percent is in lakes, rivers, streams, and soil; 1.7 percent is in polar ice caps, glaciers, and permanent snow; 0.001 percent is in water vapor in Earth's atmosphere

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.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.
An illustration of the water cycle showing how water travels from rivers and streams to clouds to snow and back again
Material:

  1. Vivid Marker
  2. Plastic bag (ziplock)
  3. 1 cup of water and half a cup of water
  4. Food colouring
  5. Litmus paper
Steps:
  1.  Grab a plastic bag (ziplock) it should be partly large.
  2.  Grab a pen and start to draw the clouds, water, trees, and words.
  3.  Pour a cup of water into the bag not too much.
  4.  add at least two drops of food coloring the color of your choice but ideally blue
  5.  Stick the bag on a window where the sun comes through regularly.

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


The Water Cycle: Bag 1
CO2 Water Cycle: Bag 2
Acid
Desert Water Cycle
Bag 3
Does it cycle?
YesYesYes
Amount of Water
222
Acidity
121

Key: Water and acidity amount: 1 = none 
2 = small drips
3 = large drips

Other comments:

  1. Water Cycle: Bag 1 - I had no acidity and the water cycled in bag 1.
  2. Water Cycle: Bag 2 - It has a small drips of acidity and small drips of water.
  3. Water Cycle: Bag 3 - It don't have any amount of acidity.

Conclusion: For our science hurumanu we did 3 bags of different water cycle, first water cycle that we did is just a water, second one we use a soda water and the last one we use a sand a small amount of water and the water cycle on bag 1 and bag 3 don't have any amount of acidity. Water cycle on bag 2 have a small drips of acidity. All of them have the same amount of water on their bag.





TODAY YOU WILL BE INVESTIGATING THE EFFECTS THAT CLIMATE CHANGE HAS ON THE WATER CYCLE.

  1. Using your SOLO hexagons poster write a paragraph about the different aspects of climate change.
  2. Write about the following Climate Change concepts:
You can do these by powerpoint, embedding a movie , on your blog, on a doc or any other form of presentation. It is up to you.


ACIDIFICATION definition:

 Is refers to a reduction of the ocean over an extended period of time. these changes in ocean chemistry can affect the behavior of non calcifying organism as well.

HOW does acidification affects climate change?

Ocean acidification refers to decreasing levels in the ocean which makes the sea more acidic. It takes long time to change in seawater because of the absorption of carbon dioxide from the atmosphere.

DEFORESTATION Definition:

Is the permanent destruction of forest, like cutting down the trees to use them for the other activity of human that needed to have a wood and some of the people that cutting the trees is selling them to make a money.

Image result for how does deforestation affect climate change



HOW DOES DEFORESTATION AFFECT CLIMATE CHANGE?

Trees is helping us have a fresh air and to absorb the carbon dioxide but if we don't have a trees the temperature is going to get hotter and hotter and it will cause a bad effect to climate change because earth hate the atmosphere is it's to hot.

ICE CAP MELT: 

Ice melting is happening because of the overall increase by global temperature. It is where icecap melts because of climate change which causes the water to get warmer and when the sea level rises it is much easier for it to melt.


Picture:

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?
Because icecaps are a dark color it absorbs more sunlight and also releases it in the air which helps climate change and that heat warms the air and melts the icecaps. 

WATER VAPOUR: 

 Water vapor is a gas it is caused by evaporation or boiling water but that is aqueous vapor water vapor is invisible.

HOW DOES WATER VAPOUR AFFECT CLIMATE CHANGE?

When we dump greenhouse gas into the air, of course, you know it makes the air humid and warmer but because of water vapor which is a greenhouse gas itself helps the carbon dioxide which makes it worse.
