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.

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...

Methylene Blue

Steam

Elephant's Toothpaste

Fire

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.

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.
