Hatching Chicks!

G'day/Kia ora/hello,

In Henderson class, we have been very busy since the start of term 3 - which is now 3 weeks ago!! We started with a new teacher - Miss Berry - and have been working hard on our fresh start and positive attitude.

So far we been looking deeply into oral hygiene - which basically means how we can care for our teeth and mouth. We heard a little rumour that some of our favourite drinks, which were full of sugar, are actually pretty bad for out teeth so we set up a little investigation to see just how bad they were.

Boiled eggs make a great substitute for teeth as they have the soft interior like the pulp and dentine but also a hard shell exterior like our teeth enamel. We chose to investigate the effect of Gatorade, Coca Cola, Lift, coffee, milk and water. To our surprise, within a couple of days Gatorade began to erode away the top brown surface of the egg shell and it wasn't long before some ants invaded on all the cups with the sugary drinks in.

So we can conclude that water and milk are the best drinks for our teeth as they made little change (and the ants weren't interested). Coffee seemed to make our egg turn dark which is why some people who drink tea and coffee have discoloured teeth. The other drinks really should be avoided or only drunk on very special occasions and through a straw to protect our poor teeth.

Crazy huh?!

This week is going to be very exciting! We will be having an incubator installed into our classroom and more eggs! Only this time they are living eggs which will eventually hatch into chicks. We really will have to be responsible and respectful learners taking care for these delicate eggs. Hopefully we'll have better results then the eggs we submerged into liquids!

Stay tuned for more updates throughout the next few weeks. We can't wait!!!
