UC / RACI Crystal Growing Competition 2013

Red Crystal

The University of Canberra is conducting its 2013 Crystal Growing Competition for Primary and Junior Secondary School students sponsored by the Royal Australian Chemical Institute (RACI).

Why be involved?

Do you want to have fun with science? Would you like to do some simple chemical experiments? Then enter the UC / RACI Crystal Growing Competition and learn all about growing beautiful crystals.

Crystals are everywhere. Just think of our daily lives. Sugar and salt are crystals. LCD computer and TV screens have many tiny crystals inside.

Where else can you find crystals? How about your classroom?

If you enter this competition, you can create your very own crystals.

Your school can order Potash Alum (potassium aluminium sulphate) from the University of Canberra.

What's involved?

The aim of the competition is to grow your very own crystals in six weeks.

There are four divisions:

  1. K - Year 3 growing from potash alum
  2. Years 4 - 6 growing from potash alum
  3. Years 7 - 8 growing from potash alum
  4. an Open Division growing any crystal.

The crystals will be grown over six weeks in terms 2 and 3.

Crystals will be judged on size, shape and clarity.
