Observations:

- There is about 172ml of solution in the beaker

- The liquid solution before filtering is foggy and unclear

- The solution after filtering is clear and water like

- There are no crystals at all that have been formed

Day 2 - 18/09/13

Observations :

- There is about 170ml of solution inside the beaker

- The liquid solution is still clear and water-like

- There are four large crystals that have formed inside of the beaker overnight

- The larger crystals that have been formed are about 1.2cm in width and about 0.9cm in height

Day 3 - 19/09/13

Observations:

- There is about 168 of solution inside the beaker

- The solution is still clear and water-like

- The four large crystals have grown bigger overnight and some other smaller (1mm in width) have formed as well on the bottom of the beaker

- The four larger crystals are now about 1.7cm in width and about 1cm in height

- When transferring the crystals from the beaker to our jars, they were difficult to pick up with the tweezers because they were very smooth and so the tweezers had nothing to grip onto

- The lid was screwed onto the jar so no dust particles could get in

- There is now only 1 large crystal in the jar

- Through the day with the lid on the jar, there have been a big development of tiny, little, glitter-like crystals around the big crystal

- The liquid is about 2.1cm high inside the jar

Day 10 - 26/09/13

Observations:

- There is still only 1 large crystal in the jar

- The crystal is about 1.1cm in height and about 1.8cm in width

- The small, glitter-like crystals from the bottom of the jar have merged together

- The liquid is still clear and water-like

- The liquid is about 2cm in height inside the jar

Day 17 - 03/10/13

Observations:

- There is still only 1 large crystal inside the jar

- The crystal is about 1.1cm in height and about 2cm in width

- The small, glitter-like crystals have grown about one-quarter of a millimeter

- The liquid is still clear and water-like

- The liquid is about 2cm in height inside the jar

Day 24 - 10/10/13

Observations:

- There is still only 1 large crystal in the jar

- I have put the jar under a desk light for about 5 hours

- The crystal is about 1.1cm in height and about 2cm in width

- The small, glitter-like crystals have grown about half a millimeter

- The liquid is still clear and water-like

- The liquid is about 1.5cm in height
