Skittles

 Skittles

Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium which the components move at different rates.

Aim: to separate the colours from the skittles by using chromatography 

Martials:

1. 5 Skittles 

2. Water

3. Petri dish

4. Beaker

Process: 

Step 1: Get your equipment set up ready to pour 25mls of water into the petri dish with the skittles.

Step 2: Place the skittles into the petri dish around the edges.

Step 4: watch as the water removes the dye from the skittles. See which  colour reaches middles fastest.

Step 5: Record your results on the tables below.  (forgot to take a photo sorry)

Floods

Few weeks ago there were floods around Christchurch and lots of other places I think that biggest flood was in Ashburton. It was really wet and cold for a couple days now it has been sunny.
Facts about the Flood in Ashburton: 
Hundreds of north Canterbury residents have been evacuated from their homes because of these flood they've broken houses, shops, etc. - and further south, hundreds more Ashburton residents are on standby 
The entire Canterbury region is now under a state of emergency and around 75 schools and preschools are closed on Monday as residents prepare for more upheaval.
Ashburton mayor Neil Brown said some locals had already started to evacuate overnight as rising river levels continued.
