Gemma makes magic crystals....

Gemma had a fascinating Teach the Teacher session. With Borax ( a household cleaning product), water and food colouring she grew pure crystals!

She also gave us some of the science behind these amazing formations.

. A crystal is made of molecules of a product that come together in a repeated pattern

. The size and shape of the crystal depends on the amount of Borax you dissolve in the water and the rate at which the water cools.

Tracks are for Trains

Although the Seniors are just finishing their Risky Business Inquiry study Rm I is not sure Gemma understood all the safety messages? Tracks are for trains Gemma!

Also we enjoyed this song by the PNBHS choir. Very topical 'I'm a train'. Stunning voices.
