Bouncy Egg 2

What did we notice?

The egg was floating this morning.

There was a lot of foam on the surface.

There were lots of bubbles on the egg.

When we took the egg out, the shell was soft and bouncy. 

Parts of the egg shell are coming off in layers.

when we put it back in the glass, the egg sank again.

Bouncy Egg

We are doing an experiment about making an egg bounce. We found out that eggshells are made of calcium, just like our bones and teeth. We put a raw egg into a glass of vinegar, which is an acid. We noticed that bubbles started to appear on the egg. Foam is beginning to rise to the surface. We will check on the egg tomorrow.

Little Blue Penguins

Yesterday Melanie Bailey talked to Room 11about the Little Blue Penguins that live in a colony in Oamaru. We learnt lots of things about what makes them different from other penguins. We also learnt about what the people of Oamaru are doing to protect these creatures.

I was impressed with the questions that students asked and the connections they made to previous learning. 

Thank you Melanie.

Photos from our show

Cheryl took these photos before and during the item. Enjoy!

The Big Slurp

"What are all these cows doing at South School?" Mrs Rodger asked.

We are celebrating 'The Big Slurp'. Lots of children slurped the milk that Fonterra provide for us every day. We know that milk is good for us - it makes our bones stronger, gives us vitamin B, and helps us grow taller than the teacher. (Mrs Rodger doesn't think you will grow taller than her. You will have to come back to visit her when you are adults so she can check).

We also love the taste of the milk.

Beeswax Candles

Yesterday Room 11made a beeswax candle. First we held the sheet of beeswax over the heater to soften it. After that we looped a piece of string for the wick. Then we rolled it over and over into a cylinder.
The classroom smelt like honey. Lots of children lit their candle when they got home.

Candle experiment

Today Rooms 10and 11 observed a science experiment showing that air has weight and takes up space. The question we were exploring was Does fire need oxygen? They were fascinated and had some excellent ideas about what was happening. We wrote it up, using a labelled diagram and a summary of what we discovered. I have included some pictures to show what it looked like if you want to try it at home.
