Coketooth Tuesday update

Well the tooth had a break from the coke at the weekend (I forgot to put it back in the coke after taking the Friday pictures!)

Here is the Tuesday picture...still in one piece and it even has some white enamel showing.

 

The picture below shows some mould which started to grow on the surface of the coke.

I wonder why that happened?

I cleaned it off with a tissue and the tooth sits at the bottom of the glass beaker.

Tomorrow is the last day of school so who knows what will be there when we get back on Tuesday 5th January.

Teeth - the latest shot - and a new word discovered, thanks to Poon

Here is the latest picture of the coketooth.

After nearly 3 days, the tooth is covered in a thick brown layer.  What will be left on Monday?



We discovered a word today thanks to Poon...chyme.  I immediately thought that Poon meant chime, as in hear the bells chime...but no!
Chyme is the word for the semi-liquid contents of your stomach as they are about to pass into the duodenum (the next place in the journey of food as it gets digested).  See here for the online dictionary definition.

Tooth picture

Here is the tooth after nearly 48 hours of being in coke.

Have you brushed your teeth today?

Teeth and Coke

The tooth from home.

What we did
We decided to put a tooth in coke because we wanted to see  what would happen. (Laure)

Prediction

I think it will go a bit stained and get holes in it and it will  dissolve. (Toby)

It will start to go black and rot then dissolve. (Ali)

I think it will disappear. (Jessie)

I think it will go rotten and black and then it will start to dissolve and then it will start to go to liquid. (Poon)

I think that if it stays in long enough then it will get holes in it and it will turn into a bit of acid. (Guilli)

What we found out...

At 2:30 - after about 6 hours, the tooth is starting to look a little bit brown...I'm glad it is not still a working tooth in anyone's mouth!

We have a holiday tomorrow - Constitution Day - Falling on December 10 every year, Constitution Day, a public holiday, commemorates the historic event on December 10, 1932, when King Prajadhipok (Rama VII), graciously presented the first-ever constitution to the Thai people. (From Ministry of Culture, Thailand website).

This means that we will be unable to show pictures of the tooth during the next 36 hours...

What will it look like when we come back to school on Friday?

Varied diet - balanced plate

What is a balanced plate?  Is it a plate which rests firmly on the table without falling off??

OF COURSE NOT!!!!

We have made balanced plates with food from all 5 food groups...can you remember their names?  Send them in as a comment.

Here's a great game to help you learn them and have fun making a balanced plate for a healthy diet.

Looking after our teeth

During this term, we learned about teeth and eating. All of us made a made a poster about looking after our teeth.

So we found out some facts. Here are some facts about looking after your teeth:

1. Don't eat more than 1 whole bar of chocolate in a day

2. Avoid fizzy drinks and sugar.

3.Cut out sugary food.

Did you know?
Some people are born with teeth.
A complete set of adult teeth includes 32 teeth.
A canine tooth is for ripping.
The enamel is the white, hard outside layer.
Some animals only have canine teeth...like crocodiles and sharks.

Digestion - What happens to my food?

Omnivores

Which animals eat meat and plants?

"Various mammals are omnivorous by nature such as bears; coatis; hedgehogs; opossums; pigs; some primates including chimpanzees and humans; raccoons; some rodents including chipmunks^[5], mice^[6], rats^[7], and squirrels^[8]; skunks; sloths.

Some lizards; some turtles.

Some fish such as piranhas.

Some insects and other invertebrates are also omnivores."

Project Homework

Here are some of the projects which we picked to show you. We read each other's facts about the number 31 and then peer reviewed (we placed post-its with our comments). There were some very creative, informative, colourful and original pieces of work. Well done to everyone who completed the homework on time! The next project homework was set today and is to investigate animal teeth and their diet.You may find out about real animals, their diet and their teeth...or you may want to invent an animal of your choice with its own specialised teeth and diet.
