Celebrating books (and some movies...ahem, Mr Mc!) Cyan decked out in their gear to parade in the 2016 Book Week Parade. Our Captains did a fantastic job hosting the event, keeping cool under pressure and using their wits to MC on the spot and off the cuff.
Feature Profile: Richard Branson
Virgin is one of the world’s most irresistible brands and has expanded into many diverse sectors from travel to telecommunications, health to banking and music to leisure. There are now more than 100 Virgin companies worldwide, employing approximately 60,000 people in over 50 countries.
Having started Virgin as a mail order record retailer in 1970, Branson founded Virgin Records and opened a record shop on Oxford Street, London. After building a recording studio, The Manor, the first Virgin artist, Mike Oldfield, recorded and released ‘Tubular Bells’. Virgin Records went on to sign household names from the Sex Pistols to The Rolling Stones, becoming the biggest independent label in the world.
How do we taste?
Taste is one of the five basic senses. Flavour is detected by combination of taste and smell. We detect the taste of food through taste cells. Taste buds contain about 100 taste cells and are located in structures on the tongue called papillae. The papillae can be seen on the tongue as pinkish bumps, particularly around the edge of the tongue, and can be more easily seen after drinking milk.
Each taste cell has a taste pore that is capable of detecting several tastes. The five basic tastes are sweet, salty, sour, bitter and umami (meaty, savoury). The taste cell contains receptors which bind chemicals responsible for sweet, bitter and umami. When these chemicals bind to their specific receptors they activate a pathway in the taste cell which sends a signal to the brain, telling us what the food tastes like. Salty and sour tastes are detected differently by the taste cells. Sodium ions in salt enter taste cells through a channel. Acid is mainly responsible for the sour taste and it is the hydrogen ions that trigger the taste cell to send impulses to the brain.
The taste map (or tongue map) which associated each basic taste with a region of the tongue, originated from a German paper in 1901 which was mistranslated into English. The map has since been scientifically disproven. We now know that each basic taste can be detected all over the tongue where there are taste buds.
The brain taste map
For our brain to perceive different tastes the taste cell receptors must send a signal to the primary taste cortex (centre) in the brain. Very recently, scientists mapped the areas in the taste cortex that were activated for each of the five tastes. Each taste signals to it’s own separate area in the brain within a region where all tastes are perceived (the gustatory cortex). Although there is no evidence for a taste map on the tongue, there is now proof a taste map does exist in the brain. This is called the gustotopic map in the brain.
Some people (25% population) are ‘supertasters’ and can detect tastes at a lower level than normal. Scientists have discovered differences in the genes that code for the bitter taste receptor that account for this variation in bitter sensitivity. As a test to study this, scientists use chemicals such as phenylthiocarbamide (PTC) or 6-n-propylthiouracil (PROP) which only supertasters perceive as extremely bitter. Non-supertasters detect a slight bitter taste or no taste at all. Supertasters are more likely to be women than men, and to be of Asian, African or South American descent. Children are more sensitive to bitter tastes than adults, which may explain why they don’t like vegetables such as brussel sprouts and broccoli. It is also thought that supertasters have more papillae than non-supertasters.

Our school has been recommended to a Taiwanese television program that is interested in doing a story about the wonderful things our school is achieving with coding and technology.
They were keen to focus on the outstanding work of our class and the technology club, and have asked to film and interview our class last week.
This holidays I hope you are enjoying time with family, friends, hobbies and passions. One passion you should definitely develop is reading. An optional homework for this holidays is to do a reading review. Write it up in your homework book, edit with a family member (or wait until you are back at school), or post it here for me to review.

Some felt that choice was debatable, some even choose other topics. Below are some of Cyan's persuasive writing--what do you think?
After so many failed attempts to get our last 3D printer working (sorry, Rob) we bought a new one. This one from a Kickstarter Project with the guys at M3D.
So, hop on TinkerCad (link click here), and start creating!
Create to play, or solve a real problem or need you have! Pitch your design to Tech Club--best designs or real problems solved gets printed! (As it takes a long time to print and the success rate of 3D printing isn't as high yet)...
Cyan, ready, set--BLOG!
Our Project for the next month is the Blogging Challenge.
1. Set up your own blog (ask your teacher for log-in details)
2. Register your intention to enter the blogging challenge CLICK HERE!
3. Follow the instructions in the Blogging Challenge and complete Task 1
I was walking towards my grandmother's home, when i saw something in the jasmine hedge. It rattled and glowed. I went closer to see to strange figure, i picked it up and fled to the inner city where i lived. When I bumped into a business man and made him drop his case into a puddle. I noticed that the dragon figure was not in my arms but was also in the puddle , the man held the dragon in one hand and his umbrella in the other. Myself in shock, the man’s face FELL OFF!!! Everyone screamed as the man’s umbrella turned into an ancient colour, blue? And transformed into a rocket, Vroom! The once business man was soon turning the whole world back to its original form, brightly covered and goofy. This was the best I felt--happy! Emotion that I have never felt overwhelmed my body. Then everyone's faces fell off but no one screamed, just laughed and smiled, I love this world and it will never be grey again. Or will it...
I really enjoyed this imaginative writing piece. Sarina's use of sentences was very effective; short sentences with long sentences. Long sentences to build detail and short sentences to add tension. She chose words well and her phrases engaged, such as "rattled and glowed" and "brightly coloured and goofy". Well done. I look forward to reading your next piece.
