Biodegradeble Packing Peanuts.

This morning I showed the class biodegradeble packing peanuts which are actually made from potato shavings. They are from my mums packaging for her Nutimetics sales, so that the products don't bang into each other and break druing transport.
This is what I did.
First I got a plastic container lid and filled it with cold water.. Next I put the potato shavings in the container lid and squashed them down. Students then observed the Packing Peanuts starting to foam up and disintergrate.
This type of packing material is better for the enviroment because unlike polystyrene it is biodegredeble.

Why Does the Water Rise?

You’ll have to watch closely...

You’ll have to watch closely and use everything that you know about air in order to explain the mystery of the rising water. You heard right! Air is the key to why the water rises in this experiment... but you'll have to do the experiment yourself to find out just how air affects the water.

Materials

• Candle and matches
• Pie pan or dish
• Juice bottle, jar, or clear vase
• Water
• Food colouring
• Matches

We followed the instruction and set on our way to discovery. Then we had questions to ask and talked our way to understanding.

The Why.

Why are there bubbles when you place the jar over the candle?
The candle flame heats the air in the vase, and this hot air expands. Some of the expanding air escapes out from under the vase — you see some bubbles escaping

Why does the water go up the jar?

When the flame goes out, the air in the vase cools down and the cooler air contracts. The cooling air inside of the vase creates a vacuum.

Simply put, the water would rise at a steady rate if the oxygen being consumed were the main contributing factor (rather than experiencing the rapid rise when the flame is extinguished).

What has air pressure have to do with it?

This imperfect vacuum is created due to the low pressure inside the vase and the high pressure outside of the vase the expansion and contraction of the gases within the bottle.

Artsplash - Dance

Arts Academy have been working hard in the last few weeks with extra lunch time pactices. We have been invited to preform at The Opera House, as part of Artsplash.
Ariel, our dance instructor, has choreographed our dance moves including ballet, hip hop and jazz. Today we travelled, by train, into town for the dress rehearsal.
Tonight we preform.
We can't wait! :)

A big thank you to Ariel and Miss Miller for all your time and effort.
