Science Decompistion

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

Hypothesis: I think that...... The Banana is going to rot the fastest

Materials:

1.   Bread
2.   Water
3.   Test Tubes
4.   Banana
5.   Cardboard
6.   Styrophone
7.   Test tube tack

Steps:

1.   Add the bread, styrophone, banana and cardboard into a test tube each.
2.   Add water to the test tube that had bread
3. Put little lids on them
4.   Put them all in the test tube rack
5.   Let it sit for about 3 weeks
6.   See what had happened to it

Findings:

TODAY	Colour	Change	Observations
Banana	Yellow	Little Brown	The banana started to go a little disgusting
Paper	Brown	Brown	The paper was just the same
Styrophone cup	White	White	It stayed the same
Bread	Cream	cream	The bread started getting hard

3 weeks	Colour	Change	Observations
Banana	Green	Mouldy	The banana had become completely mouldy
Paper	Brown	Brown	The paper stayed the same
Styrophone cup	White	white	The styrophone had mold around the edges
Bread	Green/Cream	mouldy	Was watery

5 weeks	Colour	Change	Observations
Banana	Green	Green	The banana has stated to become hairy
Paper	Brown	Brown	Its stayed the same
Styrophone cup	White	White	I has formed more mold in the tube
Bread	Cream	Bit of mold	Soggy

  

Conclusion:

This experiment was very disgusting. I didn't like it at all. The was a complete difference in 3 weeks. But this did turn out how it was supposed to and my guess was correct that the banana was going to rot the fastest There is also a very  big difference from 3 weeks to 5 weeks.

Science Week 2: Pizza Ovens

Renewable Energy
Aim: To make a solar powered oven

Equipment:

1. Sellotape
2. Scissors
3. Pizza box
4. Straw
5. Marshmallow
6. Biscuit
7. Glad wrap
8. Tin foil
9. Black plastic
10. Ruler
11. Vivid marker
12. Newspaper
13. Plastic Plate

Steps:

• Cut out the flap on the lid of the pizza box so that it is 5 cm around the edge
• Sellotape some tinfoil on the inside of the flap
• Sellotape some glad-wrap so that the whole you have cut on the pizza box lid is covered over with glad-wrap
• Put a piece of black plastic on the bottom of the inside of the box. 
• Make a paper square that fits inside the pizza box and lays around the edge
• Put a marshmallow on top of a chocolate biscuit, place it on a plastic plate and put it in the solar oven
• Put it in the sun to cook.

Conclusion:

Our experiment didn't work exactly. I think it should be in a place that the sun comes out more often and is close to our "OVENS". The smores were DELICIOUS.

Science Week 1 - Wind Turbine

Extreme weather

Measuring weather.

Aim: To test the wind to see how you would test the wind

Definitions:

1. Anemometer:
2. Beaufort wind scale:

MATERIALS

1. 2x sticks  
2. Cello Tape
3. Pencil  
4.   4x cups
5. Pin
6. Sticky note
7. Scissors

STEP

1. Collect materials
2. Tape the 2 sticks together to form a cross  
3.   tape the sticks onto the cups
4.   plug the pin through the tape
5.   stick the pin into the rubber of the pencil
6. then write your names on a sticky note and stick it onto your Anemometer

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper ( watch)

• Counter

• Recorder ( Chromebook or refill )

• Anemometer Manager ( Anemometer)

• Wind Manager

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

CONCLUSION:

This week in science we have been focusing on a wind power and how reporters tell how the weather is going to be. We had to be in a group of 5, in my group I was with Amanda, Latoiya, Bianca and Keghan.  We have made a wind power source that we are going to test in the areas above and with that we will be recording the number of spins. We have been focusing on the graph below on what the we found. There is a bit of maths that is in there but I had a little help, (Not by Cheating). This week with science was more complicated tan I had expected. I always love challenging myself aswell.

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

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	16	6-12	2
Old J Block site	10	2-5	1
Grass hill	5	0-2	0
Tennis Court Gate	3	0-2	0

WHICH IS THE WINDEST AREA AND WHY?

WHICH IS THE CALMEST AREA AND WHY?

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

1. The field is the windiest as the cars come past and make a lot of wind plus its a big space.
2. The Tennis court is the calmest as its all fenced off and there would be very little wind.
3. The best place to build a windmill would have to be the old J block site because people won't be over there most of the time and it's also out of the way of the children

CIP

Today for Community Impact Projects, we have been researching somebody that we dont know that much about. I choose to do Princess Diana (Diana Frances Spencer). Some of you guys may know that she was in a fatal car crash but didn't survive.

Here are some pictures of what I have been doing...

Oranna Wildlife Park

On Tuesday we had gone to Orana Wildlife Park. This was an amazing time apart from some disgusting things from the gorillas. We some adorable animals. My favourite animal would have to be the Meercats as they have some sanitary duty which they look out for predators.

3 things I know about climate change and how it effects the animals.

1. With the giraffes, this isn't really a bad thing it's a good thing, especially for our environment. As people are cutting down the trees the Giraffes eat seeds which when they poop those seeds come out and are now in the ground, which means they are creating more tress.
2.  With the White Rhinoceros there environment is a little bad. As they eat the grass from the ground and because of were they live there isn't much water and it barely rains there. Less rain means dryer land and dryer land means the Rhinos get extinct.
3. 
   

4 Facts I learnt:

Meercats have Sanitary duty 

Gorillas eat there own poop

Oranag would hide instead of out in the open

3 things I enjoyed:

I enjoyed seeing all of the animals and there habitats

I enjoyed some of the Birds

One of the things that I loved see is the Meercats santarty duty.

CIP Blog Post

I have chosen to do this blog post off a chart that our teacher has put together for us. Its pretty much a 3x3 bingo board and what we have to do is we have to complete 3 tasks to finish. 

What I hope to do this term in CIP:

I hope to do a lot of kindness themed things as you would get kindness back. I hope to do something like going out of school and making a card to a company close to our school. I would also like it if we could do something for the teachers that teach the older kids or even the tech teachers as they do a lot just like our homeroom teachers and Hurumanu teachers. Because they are tech teachers and they do wood work, soft materials, food etc. Maybe we could create something that they teach. For example the food tech teacher, we could cook, make or even bake something as a thank you for teaching the classes.

If you got to choose what kindness activity you would want to do and its around your school, what would you choose?

Holiday Recount

These holidays I have been doing some stuff that is tiring like packing, swimming and walking around A LOT. 

High Light:

My Highlight of the Holidays was going to the swap meet. We had left at approximately 8:20 and we got there at 8:45. With the Swap Meet, you don't swap things with people you are buying them as if you were in a warehouse. I found a lot of things at the swap meet but didn't bring any money. We had to find some motorbike boots for my dad as he needs them and we were also looking for a pot to put a plant in. I also had shoppers feet after all of this.

There was this stall that I had my eye on and had lots of squishes and rings. I was looking at some rings and I found the same one I had last year. This event is only once a year. The stuff that is at the swap meet is like old vintage stuff that people can buy and put on there cars or do something with it. This event is on the same weekend as the Belfast Racing.

Low Light:

My low light of the holidays was trying to pack to move into the new house. Packing is pretty stressful to be honest. There was also a lot of pressure on me as I was the only one packing our room. We also had to help with the others with packing the garages, bathroom and the Kitchen. 

The kitchen and garage was the hardest to do as mostly everything was in the garage but most of it was already packed and with the kitchen there was lots of glasses and food to be packed. To bring all of the junk from our old house to our new house took at least 3 days but a week to just unpack most of the essentials.

What did you do in the holidays?

This Holiday was pretty stressful if you ask me. I was tired after packing and I didn't have anything else really to do. Currently our house is a pig sti and needs to be cleaned.I hope you enjoyed reading my highlight and low light.  Goodbye
