Hurumanu-Water cycle

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 vapour 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.  2 Large ziplock bag
2.  Blue food colouring 
3.  Water
4.   Vivid
5. Baking soda
6. Litmus paper

Steps:

First bag

1.  Grab a ziplock bag
2.  Draw the water cycle on it with the professional names
3.  Pour water into the zip lock bag and seal it.

Second bag

1.  Grab a ziplock bag
2.  Draw the water cycle on it with the professional names
3.  Pour water into the zip lock bag 
4. Put 2 drops of blue food colouring into the bag
5. Put the litmus paper just inside the bag but with a little bit hanging out so that it doesn't fall into the bag
6. Seal the bag up

Findings:

I found out that condensation can start anywhere like in a bag and in the air when I didn't know that it was in the air as well because I couldn't see it.

	The Water Cycle	Acid Water Cycle
Does it cycle?	1	1
Amount of Water	2	2
Acidity	0	1

Key: Water and acidity amount: 0 = none 

1 = small 

2 = large 

Conclusion:

I have found out that it cycles small and that the amount of water if large. The Acidity is small in the water cycle, it is  0 because there was no acid put into it and that the Acid water cycle is 1 because we did put baking soda in it but it wasn't a lot.

Hurumanu-Fossil fuels

Hurumanu - Fossil Fuels.

 

Mining Fossil Fuels

What Fossil Fuels are mined?

1.   Coal
2.   Oil
3.   Natural gas

How are they mined?

1. By big machines
2. people
3. Tools
4. 

Where are they mined?

1. Oil - Sea
2. Coal - In mining caves
3. Gas - Soil and rocks

Activity: Cookie Mining

On the sheet provided you need to make two drawings of your cookie. 
1. Looking down at your cookie.
2. From Side on -  of the imaginary habitat that will live on the top of the cookie. ( trees, bushes, flax, sea, etc)

Material:

1.  Toothpick
2.   Cookie 
3.   Plate
4.  

Steps:

1.   Draw cookie
2.   Draw habitat
3.   Colour them
4.   Mine cookie
5.   Draw cookie after been mined 

Findings: What did you find out as a result of your mining?

I have found out that fossil fuels are bad for not just a=us but our environment and that we need to do something before our world gets destroyed because people and mining in every part of the world and one day our world will no longer be called Earth. It will be called Eh.

Conclusion: 

I learnt how bad mining can be. It can kill plants and woild life aswell. Animals being killed are from on top of mountains/hills and our ocean.

Hurumanu-Decomposing and recycling

Hurumanu - Decomposing and Recycling

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

Hypothesis: I think that......

Materials:

1.   Bread + water
2.   Paper
3.   Banana
4.   Stylophone
5.   4 test tubes
6.   1 test tube rack
7.     Scissors

Steps:

1.   Get your 4 tubes and polace4 into the test tube rack
2.   Cut the stylophone, Cardboard and paper
3.  Place the banana and the bread in the test tube
4.   Carefully add water into the test tube with bread 
5. Then add the stylophone and the cardboard into the test tube
6.   Then wait for 3 weeks to see which one rots the fastest

Conclusion: I have found out that the banana rots faster than the bread, Stylophone or cardboard. I thought that the bread would of rotten faster since it had water ib it but obviously not. Maybe the bread will rot faster in the 5th week.

Hurumanu-Extreme weather

Hurumanu - Wind Power

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer: A anemometer is an instrument for measuring the speed of the wind or any current of gas.
2. Beaufort wind scale: It is an empirical measure that relates wind speed to observed conditions at sea or on land.
3. Typhoon: A typhoon is an intense storm of a tropical origin.
4. Monsoon: A monsoon is seasonally direct winds that are common in eastern and southern Asia.
5. What is it when the weather is really nice and turns to hail called:

MATERIALS

1. Two sticks  
2. 4 cups  
3.   Pencil
4.   Pin
5.   Sellotape
6. Sticky note
7. Scissors

STEPS

1.   Get all of your materials from the teacher
2.   Tape the two sticks together forming an x
3.   Tape the 4 cups to the end of the sticks
4.   Put the pin into the tape that is in the middle of the two sticks
5.   Push the pencil into the pin/ Make sure that your pencil has a rubber on the end of it
6.   Put your sticky note onto one of the cups and write your name on it.

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind Manager

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the timekeeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
3. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

• Record how many times it spins and record it in the table below.

• You will need to time them and count the number of spins.

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	20
2.	Old J block site	15
3.	Grass hill in the quad	10
