All about teeth

In Science we have been learning all about teeth.

We learnt about the different types of teeth in a human’s mouth and what they are used for.   Can you remember what are your incisors, canines and molars?

Next we discussed what would happen if we didn’t brush our teeth. We also setup a science experiment to test how different liquids can stain / damage our teeth. We have used: fizzy drinks salt water,lemon juice,  tap water and vinegar

Of course.. we couldn’t really use our own teeth as we want to protect them so we’ve used an egg as a substitute. Did you know that the shell of an egg is made of a similar substance to tooth enamel!?

We will observe our teeth (eggs) every day and see what happens!

By the way,

Did you know?

  • The average person spends 38.5 total days brushing their teeth over a lifetime.
  • People who drink 3 or more glasses of fizzy pop each day have 62% more tooth decay, fillings and tooth loss than others. Put down the pop and sports drinks and pick up some nice fresh water instead.
  • If you’re right handed, you will chew your food on your right side. If you’re left handed, you will tend to chew your food on your left side.
  • The most valuable tooth belonged to Sir Isaac Newton. In 1816 one of his teeth was sold in London for $3,633, or in today’s terms $35,700. The tooth was set in a ring! (source: Guinness World Records 2002).Click here to read more about teeth!

Ukulele

Year 4 Robins Strike a Chord!

Music has been filling the air in Year 4 as the Robins began their exciting new ukulele lessons We were thrilled to welcome Mr Gaydon, who will be guiding us on our musical journey as we learn to master this wonderful four-stringed instrument.

Getting to Know the Ukulele

Before we could start strumming, we needed to learn exactly how the ukulele works. Mr Gaydon showed us the different parts of the instrument, from the body and the soundboard to the neck and the headstock. We practiced holding them correctly, ensuring our “strumming hand” was ready for action!

Goats Can Eat Anything!

One of the most important things we learned was the names of the four strings. To help us remember the notes G, C, E, and A, Mr Gaydon taught us a brilliant mnemonic that really stuck in our heads:

“Goats Can Eat Anything”

  • G – Goats
  • C – Can
  • E – Eat
  • A – Anything

The children showed fantastic focus and enthusiasm during their first few sessions. We are already looking forward to our next lesson where we can start putting these notes into practice and learning our very first chords. Well done, Robins!

Websites!

What is a Website? A Guide for Young Explorers

Have you ever wondered what happens when you type something into a computer and a page full of pictures and information pops up? That is a website! Think of a website like a digital book that lives on the internet. But instead of turning paper pages, you use your mouse or finger to move around.

Finding the Right Place

Every website has its very own web address. This is just like your house address, but for the internet! It usually starts with something like “www” and tells the computer exactly where to go so you don’t get lost in digital space.

The Logo

Most websites have a logo at the very top. This is a special picture that tells you exactly whose website you are visiting, like a badge for a school or a club!

The Menu

Just like a cafe, a website has a menu. It is a list of buttons that help you find different parts of the site, like “Games,” “News,” or “Homework Help.”

What’s Inside a Website?

When you look at a page, you will see a lot of different things working together:

  • Text: These are the words that tell you stories or give you facts.
  • Media: This is a fancy word for all the fun stuff like videos, songs, and photos that make the page look exciting.
  • Links: These are like magic doorways! When you click on a link (which is often blue or underlined text), it whisks you away to a brand new page or another website.

We then went into the media centre to explore our school website, chrome music lab and the Child Line buddy website.

Plate Tectonics

The Amazing Moving Earth: A Tectonic Adventure!

Did you know that the ground beneath your feet is actually moving right now? It’s true! Even though the Earth feels solid and still, it is busy shifting, sliding, and changing every single day. Let’s take a journey deep inside our planet to see how it all works!

What’s Inside the Earth?

Think of the Earth like a giant peach. It has different layers, just like a piece of fruit! First, there is the Crust. This is the thin, rocky skin we live on. Under that is the Mantle, which is super hot and stretchy, kind of like warm taffy. Right in the middle is the Core, which is the hottest part of all—it’s like a glowing metal ball!

The Earth is a Giant Puzzle

The Earth’s crust isn’t one solid piece. Instead, it is broken into huge chunks called Tectonic Plates. Imagine a big jigsaw puzzle wrapped around the world. These puzzle pieces are constantly floating on the hot, squishy mantle below. Because the mantle is always moving, the plates move too!

How Do the Plates Move?

Tectonic plates don’t just stay in one place. They like to dance! Sometimes they pull apart, sometimes they crash into each other to make mountains, and sometimes they slide past one another. They move very, very slowly—about as fast as your fingernails grow!

  • Spreading Apart: When plates move away from each other, new land is made from hot lava rising up.
  • Crashing Together: When plates bump into each other, they can push the ground up high to create huge mountains like the Himalayas.
  • Sliding Past: When plates rub against each other, they can cause the ground to shake, which we call an earthquake!

The Great Land Drift

Millions of years ago, all the continents were huddled together in one giant super-land called Pangaea. But because the tectonic plates kept moving, the land started to drift apart like rafts on a lake. This is why the map of the world looks the way it does today, with big oceans between the continents!

Even though we can’t feel it, the continents are still drifting. One day, millions of years from now, the map of the Earth will look completely different again. Isn’t our moving planet amazing?

We use our teeth everyday don’t we?  so… It’s important to learn about them right?

To begin the lesson,  Mr Lo introduced a video about teeth to the class.

Then, (Thanks to Mrs Calbreath)  Mr Lo was able to share some teeth with year 4. They had lots of fun identifying all the different kinds of teeth. (well mostly… some found it a little vile! )

Can you remember the different teeth and their functions?

This week Mr Lo has handed out an extension Brush Your Teeth monitoring sheet.
