Chromatography

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

Aim: To separate the colours from the skittles by using chromatography.

Materials:

1. 6 skittles

2. water

3. petri dish

4. beaker

Process:

Step 1: Get your equipment set up ready to pour 50mls of water into the petri dish with skittles

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

Step 3: Pour 50mls water gently into the middle of the petri dish

step 4: Watch as the water removes the dye from the skittles. See which colour reaches the middle fastes

Osmosis - gummy bears

 Osmosis: The movement if solvent through the wall of a solid.

I want to find out what happens to gummy bears when we put them into different liquids.

I am predicting that the gummy bears will grow in the liquids

Equipment:

three solutions - water, sugar and salt

four gummy bears of the same colour

two dishes

marker pen

Electronic balance

measuring cylinder

beaker

Solvent	dry	wet
Water	Red 2.46	5.94
Salt water	Clear 2.48	3.90
Sugar water	Yellow 2.45nu	6.01

 Findings:

The water that was included in the first gummy bear dish made the gummy bear change from a dry weight of 2.46 to a wet weight of 5.94. The difference between the two weights was 3.48. This means that the gummy bear absorbed 3.48 grams of water though the process of osmosis. Te salt water gummy bear dish has a change from a dry weight of 2.48 and a wet weight of 3.90 that mean the different's was 1.92 grams. Lastly we did one last one with sugar water. When the bear was dry it was 2.45 gram and when it was wet it was 6.01 the difference was 3.56. 

Canterbury mas flood

The floods that have been going on for about 4 days  have caused a tragic event.  Farms have been ruined and some animals drowned. This bad amount of rain only happens about 100 years! The rain has has made the Waimakariri River and the Ashley River to flood and caused bridges to collapse. The Ashburton bridge slumped and now its flooded. Did you suffer from the flooding?

3d shapes

 In maths we learnt about 3d shapes. we had to make 3d shapes with play dough and toothpicks. we had a sheet that had different shapes on it so we had to make the shapes with the play dough and tooth picks.
