Water Cycle

 Hi,

This term we continued our water cycle in science from last term. Then we all answered the questions all together in the mat. Then we keep writing down the answer in our blogs after we have done it we have to show it into a teacher. So this is the blog post that we have done

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

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.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

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.  Water
2.  Bag
3.  Soda water
4.   Food colouring 
5.  Litmus Paper
6. Vivid
7. Sand

Steps:

1. Get the vivid and the bag 
2. Draw the water cycle outside the bag
3. Then put one cup of water or Soda water
4. After that put two drops of food colouring  
5. Put a litmus paper hanging inside the bag and don't get it wet
6. Hang the bag against the window to get sunlight and starts to condense 

Two Images:

Findings:

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

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Other comments:

1: Bag 1 cycled water.

2: Bag 1 had a small  amount of water 

3: The acidity in the Bag It was low

4: Bag 2 has a Acid

5: The Amount of was small

6: The Acidity was Large

7: Bag 3 Has sand 

8: The amount of water was small

9: The Acidity was large.

Conclusion:

In the Bag 1 the Cycled water has a small amount of water and the acidity was low. The Bag 2 has a acid and it is different from the first one. The amount of water was small and the acidity of it was very large because we have put soda in it. The Bag 3 was a sand and the amount of water is small the acidity was large.

Draw a labelled diagram of the Water Cycle

Water cycle words:

1. Precipitation
2. Hurricanes
3. Acid rain
4. Evaporation
5. Carbon Dioxide
6. Water
7. Defirestation
8. Water vapour
9. Transpiration
10. Flooding

SOLO Hexagons Activity

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.
