Decomposition/Recycling - Hurumanu

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

Hypothesis: I think that either the banana or the bread with water is going to rot the fastest.

Materials:

1. Bread  
2. Water  
3. Paper 
4. Banana  
5. Stylophone  
6. 4 test tubes  
7. Test tube rack  

Steps:

1. Collect materials  
2. Sort out the materials in the correct order 
3. Add in each of the 4 equipment in each separate 4 tubes 
4.  Get a sticky note from the teacher and write your names on it

Findings:

3 weeks	Colour	Change	Observations
Banana	Green	Rot	It turned into green rot
Paper	Brown	Nothing changed	Nothing changed, it still looks the same
Stylophone cup	White	Nothing changed	Nothing changed, it still looks the same
Bread	Light Brown	Mushy	It turned into this weird

Conclusion:

In conclusion, I would like to say that I have learnt a lot.  I have out how long it takes for stylophone to rot it takes thousands of years.  So that means that it takes the longest to break down.  Banana is also the easiest to rot out of the four it had already gone mouldy.  I'd like to finish off with I would like to do this again and bye.

Types of renewable energy - Hurumanu

Aim: To make a presentation that investigates different renewable energy.

Section 1: Title Page

Make a title page that incorporates all renewable energy 's Hydro, Solar, Wind, and Wave.

Section 2: Definitions

Define and provide a picture of each energy type.

Hydro Energy

Hydropower or hydroelectricity refers to the conversion of energy from flowing water into electricity. It is considered a renewable energy source because the water cycle is constantly renewed by the sun. Historically, one of the first uses of hydropower was for mechanical millings, such as grinding grains.

Solar Energy

the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.

Wind Energy

Wind power is sustainable and renewable energy and has a much smaller impact on the environment compared to burning fossil fuels. 

Wave Energy

This energy can be used to run turbines, and there are plenty of places where the winds are strong enough to produce a continuous wave motion.

Section 3; Investigate each of the 1 Energy Types.
(Hydro) 

1. Type: Hydro
2. Is it used in NZ? Yes in MacKenzie Basin
3. Other Countries that use it? Austria, Canada, Norway and many more
4. How is it used to generate electricity?
5. Draw and label a diagram of the main parts of the electricity generator? This can be done on paper and uploaded or on a drawing program on your device. I do not want any Internet images or pictures. They must be hand-drawn using a ruler and labeled

Section 4: Renewable Energy in the future.

List 10 ways that renewable energy will be used in the future to replace our current activities.

Renewable Energy - Hurumanu

2. Sellotape the tinfoil onto the flap you have cut
3. In the inside of the pizza box, place a glad wrap to cover the hole.
4. Use the black piece of paper to cover the inside of the pizza box leaving the hole the glad wrap that you used to cover the hole.
5. Then wrap the newspaper a small pole and place around the inner newspaper
6. Place contents(food) and put a ruler to hold up the tinfoil then leave it out in the sun

Hornby high vision

Today at Hornby high we worked outside and pulled out a lot of weeds.  This meant that we had time out of class and we were learning how to properly pull out weeds (from the root).

We pulled out a lot of different things that we didn't know.  It was fun to have time out of the classroom to work on something for the future. 

I hope that we do this more often and we get more time outside.  Thank you and bye.

Investigation on climate change - Hurumanu

My Investigation on climate change

ACIDIFICATION
DEFINITION: THE ACTION OR PROCESS OF MAKING OR ACIDIC.
What is happening to the oceans?
The oceans are absorbing the CO2, But it does take away the CO2 and that is a good thing but...

What does this do to shellfish?
The shellfish in the ocean, where the CO2 gets absorbed, they don't grow as they are supposed to or they are growing at a slower rate every year.

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


DEFORESTATION
DEFINITION: IT IS A WIDE CLEARING OF TREES IN AN AREA.
What are trees used for?
Trees help us breathe and to control the weather as well...
As for us humans breath in oxygen, we exhale carbon dioxide, so the trees take away the Carbon dioxide to make the weather a little bit better.

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

ICECAP MELT
DEFINITION: THE MELTING OF THE POLAR ICE CAPS IS CAUSED BY THE OVERALL INCREASE IN GLOBAL TEMPERATURE, AND THIS MELTING CAN HAVE SERIOUS CONSEQUENCES FOR ALL ORGANISMS ON EARTH. AS THE POLAR ICE CAPS MELT, SEA LEVELS RISE AND THE OCEANS BECOME LESS SALINE.
If all the ice melted what would happen?
The sea levels would rise and close coast city would be underwater...

HOW DOES ICECAP MELT AFFECT CLIMATE CHANGE?

WATER VAPOUR
DEFINITION: A DISPERSION, IN AIR, OF MOLECULES OF WATER, ESPECIALLY AS PRODUCED BY EVAPORATION AT AMBIENT TEMPERATURES RATHER THAN BY BOILING.
HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE?
The Vapour and water contribute by making vapor to form clouds but...
if there aren't enough clouds or if there are too much, they could mess up the weather,

Two days with my cousins

In the holidays,  I went to Oamaru and when I came back my dad got a phone call from my cousin.  She asked if I would like to stay over for two nights,  my dad said that it was up to me.  In my head, all that I could think about was not cleaning up my room or the lounge and how much fun that it might be.

I then said yes and when we arrived home my dad must've forgotten or something because he didn't take it instead he just watched movies.  I then told my cousin to pick me up.  A couple of minutes later they came.  I arrived at there house and we stayed up watching some bridal and groom entrances for some odd reason.  We then went to bed.

As usual, I was the first one to wake up.  I woke them up and then we had breakfast we had toast.  We then had to pack lunch but my cousin chucked a bunch of random junk foods like chocolate, chips and a mountain dew drink.  We then planned out our day, we would go to Margret Mahi and then we would leave the park and go for a walk.

When we arrived at the park my cousins Kathy and Rosetta wanted to leave and go for a walk immediately so we left straight away.  Since Rosetta was from Aukland we wanted to show her our new Christchurch Library.  It was so cool they had so many different kinds of books they even had a game station which in my mind was amazing.  They had games like NBA 2k 19 and many more.  They even had a  Foosball table.  We took some photos and then we left.

After going to the library we went for a walk down a place with heaps of shops.  Rosetta wanted to go to a beauty salon for some reason and when we got there we waited for ages.   After we had gone to the salon we went to a table and ate some of the delicious lunch as in very unhealthy.

After that, we took some more photos of us and the unique street art around the area.  We then started making jokes and was then exhausted from all of that walking.  When we got I forgot to bring my own change of clothes so I showered with a new towel and wore my uncle's clothes which were very baggy on me so I wore a belt.

We then went to Westfield where we played at timezone.

This was a great experience and bye.

Making anemometer - Hurumanu

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer:

It is an instrument used to measure winds

1. Beaufort wind scale:

It is on land in the water

MATERIALS

1. 2 sticks

2. Pencil

3. Celetape

4. 4 cups

5. Pin

6 Sticky note

STEPS

1. Tape 2 sticks together to create the cross
2. Connect all 4 cups on both ends of the sticks with tape
3. Push in the pin in the center of the two sticks
4. Well done you have created an anemometer

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.

WHICH IS THE WINDEST AREA AND WHY?

Field because there are no buildings surrounding it, therefore, letting the wind to be more powerful

WHICH IS THE CALMEST AREA AND WHY?

Tennis court gate

the gate is surrounded by trees

WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?

Field because a lot of wind will come through

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

CONCLUSION:

In conclusion, I have learnt that an Anemometer is an instrument used to measure how strong the wind is.  This means that they will have an object that says how strong the wind is blowing.  I know this because we got the chance to make our own.

Although we did not use it we got the chance to create one first hand.  But the Anemometer is not the only tool used to identify how strong the wind is.  I have also learnt how to know how strong the wind is with a Beaufort Wind Scale is something you use to identify what it means to how many spins that the Anemometer makes.  You will see an example when you continue down from my blog.

As always I have learnt so much about these powerful elements such as the good and the bad.  I would like to say that this was the most interesting science class that I have had.  I thank the teachers for this amazing lesson and goodbye.

Planting trees

Today I had the privilege of planting a tree.  We did because we wanted to make a small forest for the future.  So that the newcomers had the chance to work in a natural environment.

We got the plants from plants for canterbury and their goal is to plant 10 million trees in Christchurch.   I planted the tree in less than a couple minutes and helped others.

In conclusion, I would like to say that I hope that anyone in the following years will have the chance to work in a new place.

Stop motion stars

Today we have just started to film our creations.  Our manakitanga stories have started off really good.  We have five characters they all have their part to play and there different unique features.  Although some of our characters look good the only thing that I would change is the Ice Cream Truck,  in my opinion, I think that if we put more effort it would have been way better. 

The first scene is going really good we have shown what's not meant to be happening so the opposite of  Manakitanga. 

Although we have just started I think that this stop motion will turn out great.   I know this because we have put a lot of detail into our work.  I can't wait to post this on my blog. :)
