Hurumanu-Decomposing

Decomposting

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

Hypothesis: I think that...... the bread will become liquid and be all mouldy

Materials:

1. Beakers  
2.   Beaker holder
3.   bread
4.   banana
5.   styrophone
6. cardboard  
7. water    
8. 
   

Steps:

1.   Get your materials
2.   put some water into one of the beakers
3. but the food, cardboard and styrophone
4.   wait 1 week then check  and repeat
5.   
6.

Findings:

TODAY	Colour	Change	Observations
Banana	Green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	white	Nothing	it has stayed the same
Bread	yellow	Melted	the bread soaked up the water and melted

• the banana started to shrink  
•   the paper stayed the same
•   the styrophone cup did not get effected
• the bread started melting

3 weeks	Colour	Change	Observations
Banana	green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	white	nothing	it has stayed the same
Bread	yellow	Melted	the bread soaked up the water and melted

•   the banana got more green and hard
•    the paper stayed the same
•   the styrophone cup did not get effected
• the bread melted more

5 weeks	Colour	Change	Observations
Banana	green	shrunk	it shrunk and has green mould growing
Paper	brown	nothing	it has stayed the same
Styrophone cup	White	nothing	it has stayed the same
Bread	yellow	melted	the bread soaked up the water and melted

  

•    the banana was like a curled stick with mould on it  
•    the paper stayed the same
•     the styrophone cup did not get effected
•    the bread melted into a hard liquid

Conclusion:I enjoyed this experiment and I learned that bread and water dont mix and banana goes hard and curly with mould on it.

MY INVESTIGATION.

• Choose 3 items from the list.
• Investigate them using Google.
• Answer the 4 questions below.

Name: 

1. How long does this resource take to decompose?
2. What resource / fossil fuel are they made from?

4. How is this resource recycled?

Hurumanu-Wind Power!!

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer: an instrument for measuring the speed of the wind, or of any current of gas.
2. Beaufort wind scale: The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale
3. typhoon: A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. 
4. monsoon:Monsoon is traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation, but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with the asymmetric heating of land and sea
5. what is it when the weather is really nice and turns to hail:As the article explains, hail formation occurs "when strong currents of rising air, known as updrafts, carry droplets of water high enough that they freeze." The higher these droplets get, the cooler the temperature, even during a hot summer. ... In fact, warmer weather might actually result in a stronger updraft.

MATERIALS

1. 2 sticks 
2. 4 cups
3. sellotape  
4.   pencil with eraser at bottom
5.   pin  
6. sticky note

STEPS

1.   Get your materials
2.   Put your 2 sticks in a cross shape
3.   Put your four cups on the end of the sticks (2 on each stick)
4.   Tape the cups
5.   Tape the sticks in place 
6. Get a pencil and a pin
7. Pin goes in the rubber of the pencil through the tape

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 time keeper 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.

CONCLUSION: I learned that there is so many different wind speeds for different places

Wind

Beaufort Wind Scale

Instructions:

• Go to the measuring place and set up your wind gauge.
• Make sure everyone in your group is ready to start their roles.
• Record how many times it spins and record it in the table below.
• Count the number of spins in 15 seconds.
• Record it on your chart.

FINDINGS

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	20
2.	Old J Block site	15
3.	Grass hill in quad	10
4.	Tennis Court gate	3

• USING
•  A4 PAPER DRAW YOUR RESULTS ON A GRAPH.
• TAKE A PICTURE OF THE GRAPH AND UPLOAD IT TO YOUR BLOG

WHICH IS THE WINDEST AREA AND WHY? the field because its open

WHICH IS THE CALMEST AREA AND WHY?the tennis court gate because it is sheltered with trees 

WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL? in a big open area

CONCLUSION: 

I really enjoyed this research and investigating all of the different parts of wind and i all so learnt the amount of wind in different places of my school.

Wind

Beaufort Wind Scale

Beaufort Force	Wind Speed (KPH)	Spins	Indicators	Terms Used in NWS Forecasts
0	0-2	0	Calm; smoke rises vertically.	Calm
1	2-5	10	Shown by direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	Wind felt on face, leaves rustle; ordinary vanes moved by wind.	Light
3	13-20	80	Leaves and small twigs in constant motion; wind extends light flag.	Gentle
4	21-29	130	Raises dust and loose paper; small branches are moved.	Moderate
5	30-39	190	Small trees in leaf begin to sway; crested wavelets form on inland waters.	Fresh
6	40-50	250	Large branches in motion; whistling heard in telephone wires; umbrellas used with difficulty.	Strong
7	51-61	320	Whole trees in motion; inconvenience felt walking against the wind.	Strong
8	62-74	390	Breaks twigs off trees; generally impedes progress.	Gale
9	75-87	470	Slight structural damage.	Gale
10	88-101	550	Seldom experienced inland; trees uprooted; considerable structural damage occurs.	Whole gale
11	102-116	640	Very rarely experienced inland; accompanied by widespread damage.	Whole gale
12	117 or more	730+	Very rarely experienced; accompanied by widespread damage.	Hurricane

Based on your findings what was the Wind Speed and the Beaufort Wind Force for each area.

	Spins per minute	Wind speed ( kph)	Beaufort Scale
Field	80	13-20	3
Old J Block site	60	13-20	3
Grass hill	40	13-20	2
Tennis Court Gate	12	6-12	1

My Holidays

My Holidays

My holidays were pretty boring because I didn't do much and I ended up very bored and thinking what can I do ?

So my first highlight was going to the mcleans island swap meet on friday. me and my dad spent about $179.50 on old junk that we clean up,put away,display or sell. the prices on some of the old junk there was crazy like $15 for a hot wheels 73 ford falcon xb coupe but yet i payed $1 for a vintage hot wheels then go home research it and find out that it is worth from $50-$178 now that's a good buy but me and my dad spent 3 hours walking around the swap meet about 2 times.                                                       

  My second highlight was I went to my cousins house for a sleep over and to see my black cat. so I enjoyed seeing all of my cousins and my black cat . my favorite cousin got me into animating on flipaclip and I found the perfect meme for it it was a dancing dinosaur. making strange noises so I have started drawing the individual slides ad it is a lot of work to do but in the end it will be great.
