The science of fire and colour

Last week, Room 15 explored how different materials burn different colours. We also played around with 'homemade lava lamps' again by working with density.

Be the change you want to see in the world!

Rainbow milk!

Today, room 15 had a go at making rainbow milk using milk and detergent. We learned all about how detergent and dishwashing liquids loosen up and eat through fats in the milk to spread the colours. We tested both slim and full milk to test the different reactions. Check out some of the reactions we got!

More science!

We had a visit from Jeremy Buckley (Quincey Buckley's Dad) today.  He is very enthusiastic about science and has loads of knowledge.  He shared a few science REDOX experiments with us...

Redox (shorthand for reduction/oxidation) describes all chemical reactions in which atoms have their oxidation number(oxidation state) changed.

The term redox comes from the two concepts of reduction and oxidation. It can be explained in simple terms:

• Oxidation describes the loss of electrons by a molecule, atom or ion
• Reduction describes the gain of electrons by a molecule, atom or ion

Which gains and loses electrons can be easily memorised by the abbreviation OIL RIG, which stands for, "Oxidation Is Loss," or losing electrons, and "Reduction Is Gain," or gaining electrons.

But there are exceptions.

Kereru Syndicate Waiata

Each Tuesday and Thursday afternoon the Kereru syndicate join together to sing waiata.  The singing of waiata supports the teaching and learning of te reo Māori. This week we have been learning A haka ma and AEIOU, the actions too!

Red Cross Journey!

Yesterday morning we had visit from Inge De Leeuw, the Community Fundraising Coordinator in the Wellington/Wairarapa region for the New Zealand Red Cross.  She came to talk to the Kereru syndicate about the 'Red Cross Journey'.  

The Red Cross Journey is an online fundraising event. From 8th May, every step our class takes during a normal day will be counted towards our target.  Here is a link to Room 15s fundraising page:

What's cooler than being cool? Ice cold. (alright x 8)

We had a visit from Jocelyn Turnbull, Cameron John's Mum, on Monday.  Jocelyn works as a Radio Carbon Science Leader at GNS Science.  She came to share some fascinating stuff about dry ice and liquid nitrogen.  It was cool!...excuse the pun.

The MAD Scientist meets a REAL Scientist

Mad Scientist!

MAD Scientist

We had a visit from the 'MAD Scientist'  (Mr. Norman) today as part of our Science LAUNCH.  He did the 'Elephant Toothpaste' experiment.  IT WAS COOL!
