Popcorn for Christmas
And this one too!
What Makes the Popcorn Pop?
Moisture + Heat = Popped Corn
Popping corn is a type of corn which explodes from the kernel and puffs up when heated.
Here's how it works:
Each kernel of popcorn has a tiny amount of moisture and oil at its starchy heart, inside a strong outer shell that keeps the moisture from escaping.
When we apply heat to popcorn kernels -- by exposing the kernels to very hot air or hot oil -- and bring the temperature inside the corn up past the boiling point, the moisture in the kernel turns into steam. The steam is under a lot of pressure, trapped inside the moisture-proof hull of the corn.
The pressure continues to increase until the breaking point of the hull is reached. The hull breaks open rapidly, causing a sudden drop in pressure inside the kernel. There is a rapid expansion of the steam at the same time, which expands the starch and proteins inside into an airy foam. As the foam rapidly cools, the starch and protein set into a crispy puff.
In short, popping corn is a bit like the lid blowing off a pressure-cooker, if you forget to lock it down.

Making Yoghurt with Aggie
view and discuss the process of making yoghurt
identify the steps
record the steps/sequence on a flow chart using pictures and captions
sample the yoghurt and discuss the taste
Today Aggi came in to make yoghurt with us. This was the process. We used a flow chart to record the process.
- Sterilize the milk. Even though your milk has been pasteurized, it will still contain bacteria. Pour milk into a pot . Use a metal spoon for stirring. Heat the milk until it is almost boiling. You'll see small bubbles form around the edges and steam beginning to rise. Keep checking the temperature: It should be around 82-85C. Aggie goes by feel.
- Cool the milk to grow the yogurt. Allow the milk to cool at room temperature . Stir frequently to make temperature checks more accurate. Don't proceed until the milk is below 49C and don't allow it to go below 32C . Aggie tests it and now knows the feel of the correct temperature.
- Warm the starter. Let the starter yogurt sit at room temperature while you are waiting for the milk to cool. This will prevent it from being too cold when you add it in.
- Add nonfat dry milk, if desired. Adding about 1/4 cup to 1/2 cup nonfat dry milk at this time will increase the nutritional content of the yogurt. The yogurt will also thicken more easily.
- Add the starter. Add 2 tablespoons of the existing yogurt
- Put the mixture in containers. Pour your milk into containers. Cover each one tightly with a lid.
- Allow the yogurt bacteria to incubate. Keep the yogurt warm to encourage bacteria growth. Between 41C and 49C is ideal. Aggie used a chilly bin and containers of hot water. She also used towels to wrap around the containers. Keep the yogurt still during this process. It can take anywhere from 8-14 hours to incubate.
- Refrigerate the yogurt. Place the yogurt in your fridge for several hours before serving. It will keep for 1-2 weeks. If you are going to use some of it as starter, use it within 5-7 days, so that the bacteria still have growing power. Whey, a thin yellow liquid, will form on the top. You can pour it off or stir it in before eating your yogurt. Aggi told us she uses a thin tea towel to strain it. She leaves it so that the whey drips into a bowl.

This a poem we are using to write character descriptions of Santa
'The Night Before Christmas' but originally it was titled 'A Visit from St Nicholas'
He was dressed all in fur from his head to his foot,
And his clothes were all tarnished with ashes and soot;
A bundle of toys he had flung on his back,
And he looked like a peddler just opening his sack.
His eyes how they twinkled! his dimples how merry!
His cheeks were like roses, his nose like a cherry;
His droll little mouth was drawn up like a bow,
And the beard on his chin was as white as the snow.
The stump of a pipe he held tight in his teeth,
And the smoke it encircled his head like a wreath.
He had a broad face, and a little round belly
That shook when he laughed like a bowl full of jelly.
He was chubby and plump,--a right jolly old elf--
And I laughed when I saw him, in spite of myself.
Written by Clement C. Moore in 1822 as a Christmas present to his children.

Advent
Click on the advent calendars to find out what is behind each date. Visit these sites each day. We will check them out at school too.
What is advent?
Advent is the start of the Christmas season. It begins on the Sunday nearest November 30 and lasts four Sundays. The date it begins changes from year to year. As a result, so does the length of each Advent season.
(This year the first Sunday in Advent is Sunday November 30, 2008)
The word advent, from Latin, means "the coming." It is a time of spiritual reflection as well as cheer and anticipation. This time includes the ceremonial lighting of candles in the Advent wreath.
An Advent wreath is made from greens to symbolize continuous life and contains four candles— three purple and one rose. Often a fifth candle (white) is added to the center of the wreath for lighting on Christmas Eve, in celebration of the birth of Jesus
Yoghurt Label Designs
We need...
- Colourful picture
- Catchy title (easy to read and eye-catching)
- Nutritional panel with energy, protein, fat (total and saturated), carbohydrate (total and sugars), sodium, calcium
- Border around nutritional label and where needed
- Information about the yoghurt
- Bar code (if wanted)
- Placement of text,tables, picture, title (juxtaposition)
Never Never Land Pantomime
As their light wavy arms swayed to and fro, my mind bubbled with thoughts, one of them was that I knew the music made me want to go somewhere, but I couldn't think where, so I sat there thinking and listening. As they gracefully moved into place I suddenly felt relaxed. Not long after I was staring bug-eyed at the stage nearly asleep. I loved the moves as they glided across the green lighted stage. I could see they had been practising for a long time because if they could make me nearly go to sleep they could make anyone do anything. They pranced around to the song of nature that was playing.

The Mad Hatter's Tea Party
The curtains open and I felt nervous. I saw three hundred people. in the audience. The middle syndicate was watching as well. I started saying my words. At one point I felt so scared, i nearly fell over
I had three colours on my face - black, white and grey. Guess what? I kept the same face paint on for the card dance! I was the tree of clubs.
I really thought my parts in the pantomime were cool because I was allowed to become another person. in my first scene I was the Mad Hatter and in the next scene I got to be the three of clubs so I had to change character and costume quickly and get into role

Taste Tests
... write an acrostic poem to describe yoghurt
... view the labels on our pottle of yoghurt locating the type of bacteria eg acidophilus
... discuss the parts of the label & nutrition facts panel
... create an advertisements for a new yoghurt or a label for a new yoghurt using a title/name of the yoghurt, colour to attract attention, slogan, nutritional facts, description of product, bar code, juxtaposition(placement) and any other mportant information needed
Today we tasted a variety of yoghurt, then wrote at least 9 words or phrase to describe the experience. We also wrote an acrostic poem for writing. We worked in a group to view the packaging/label on the yoghurt pottle. We discussed the visual features on the label, such as title or name of yoghurt

Writing - Opening my present
WALT
... use strong adjectives and verbs
... write a snapshot in time
... plan using a web or bubble map
... proof read and edit our work
... share our work with a friend or class
When I got to open my Christmas present I opened it up gently. I felt it first. I stared at the Christmas wrapping and the curling ribbons. I heard a rattling sound underneath the Christmas wrapping. The paper crackled as I opened it.
Samantha Year 3
It was something I had always wanted. It was in a plain bag. I felt it and it was very smooth. I pulled it out. It was a grey laptop. I jumped around with glee. My Dad plugged it in and I played until I had to get off. I was really sad to leave the best present ever!
Jake Year 3
It was my birthday. Yae! I ran to the living room, looking forward to opening my presents. That's when I screamed, and "Twenty presents just for me!" One of then looked particularly good though. I went towards it, staring at it as if it were an alien intruder. I shook it and shook it again, trying to work out what it was. The shinning golden glimmering paper shone in the sunlight. As slow as a turtle, I carefully opened the paper.
Maia Year 4
The present was heavy and hard to squeeze. I shook it with excitement. The warapping was colourful. I shook it and squeezed until I could find out what it was. It felt like a game to me and then I finally unwrapped it.
Nadia Year 3
It was Christmas morning. I woke up early. I crept into the lounge. It was silent. I tiptoed over to the tree. Suddenly the door burst open and my two brothers rushed in. We got into a fight about who was going to open their presents first. My present was ... rectangular, hard, curious, rattly, had a bow and was clattery. Finally it was my turn to open my presents. I got a giant remote-control car!
Nic Year 3
My present rustled. My heart beat faster. I tore and tore at the wrapping paper. It seemed like ages waiting for the surprise present to open. It opened to reveal a book of 'Folk and Fairy Tales'. I gasped in surprise. Excitement filled my lungs.
St Claire Year 4
The gold wrapping paper sparkled as I ripped it open. A huge silver bow was just one of the many obstacles keeping me from uncovering the treasure. Excitement filled me like a Sunday's bacon and egg treat. I stared hard at the huge cardboard box I had unwrapped.
Courtney Year 4
My eyes opened. I rushed to the living room. When I was the Christmas tree my heart skipped a beat. There were piles of presents all around the Christmas tree. I ran through to Mum's room and woke them both up. I was really, really excited.

What is Yoghurt?
Bacteria are one-celled organisms. They produce one or more kinds of acid as by-products of their metabolism.
Some bacteria are used in making fermented foods; most of these bacteria produce lactic acid. It is the lactic acid which gives most fermented foods its taste. One example of a fermented food is yoghurt. If lactic acid producing bacteria are added to milk, they use the sugar in milk for food and make lactic acid as a by-product of their metabolism.
The lactic acid grows in the milk, making it taste sour and causes it to become thicker. It gets thicker because the proteins in milk denature and coagulate, giving a custardy texture to the milk. When this occurs, the product is called yoghurt.
We will look up and discuss these key words on Monday:
bacteria, texture, denature, coagulate, custardy, metabolism, fermented, lactic acid, by-product, one-celled organism, acidic, yoghurt
You might like to discuss the last two postings with family and friends over the weekend. Maybe you could have a look at the ingredients in a pottle of yoghurt and the nutritional value of yoghurt. Be prepared to discuss your findings on Monday!

Writing and Dance
We were looking at the Communicating and Interpreting strand of the Art's Curriculum
- Share dance movement through informal presentation and share their thoughts and feelings in response to their own and others’ dances.
- Share dance movement through informal presentation and identify the use of the elements of dance.
Erosion
Here are our WALTs
- The surface of the Earth changes. Some changes are due to slow processes such as erosion and weathering
- Landforms are the result of a combination of constructive and destructive forces. Destructive forms include erosion and weathering
- Soil consists of weathered rocks and decomposed organic material
We found out that soil runs off the soil quickly at first, taking some of the top soil with it. The water that collects in the second tray contained dirty water. We let it settle and found out there was a lot of silt or sediment. After the top soil came off, there were a lot of stony soil below it. We thought that if the soil was wetter it probably would soak in more rather than run straight off. We added two of our National Curriculum Maths books to make the slope steeper. The water ran off quicker and caused more erosion. We discussed ways and we thought that
planting trees and plants would help because the roots hold the soil.
We then talked about local farms in the area especially the ones under Mt Aspiring. We thought that the land would be fertile because the top soil would run off onto the flat areas
We used this picture from the NZ ARBs to look at...
The diagram shows a river flowing through a wide plain. The plain is covered with several layers of soil and sediment.
We had to
1. Write down one reason why this plain is a good place for farming.
2. Write down one reason why this plain is NOT a good place for farming.
We came up with many great ideas. Read some of them...
- the soil is fertile (good), abundant
- there is a river (for irrigation, water for animals)
- there is plenty of space or flat areas for farm land
- there is the possibility of flooding, or that the soil will be too wet
- there is the possibility of wind or water erosion
At the spot marked X, the river is wearing away the riverbank. What are two things that could be done to stop the riverbank being worn away?
Here are some of our answers
- Plant trees
- Change course of river, i.e., straighten.
- Use boulders/concrete to protect bank.
- Change the river channel away from this part of the river bank.
- Build a stop bank
- Build a dam
