**Teacher Comment: Beautiful bright colourful display Bethany it looks fantastic. This is a great experiment to do so that you know what orange juice is best for you in terms of the Vitamin C!! I learnt a few things while you were presenting this like how the unripe oranges have more Vit C in them - so great that you have written a fantastic explanation for this Bethany you have done a great job :)** **Student Comment:**

__Kitchen mayhem__

Aim- To find out which A,B,C,D,E has either Icing sugar, Baking soda, Salt,Cream of tata or corn flour.

__Hypothesis-__ A.Icing sugar B.Salt C.Baking soda D.Corn flour E.Cream of tartar

__Result-__ A.Corn Flour B.Salt C.Baking soda D.Icing Sugar E.Cream of Tartar

 __Equipment-__ Tea spoon Beaker <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Vinegar <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Iodine <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Linton

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Method- <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">1.You have to get container A and scoop a tea spoon of it then put it in the beaker with water then put the iodine and see if it goes blackish purplish. And just repeat that to all the containers of the other ingredients and you will get all the right answers.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Reflection- When I did this experiment I learnt what cream of <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> tartar is and that it is a acid.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Explanation- <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">The reason vinegar and baking soda fizz when mixed is because the vinegar and bakind soda have some Atoms in common. These cancel each other out. The left over atoms create water and a type of salt(not table salt) and carbon dioxide is released. This creates that fizz.

Some information about fingerprinting for you! The different types of patterns in fingerprinting. \

<span style="color: #ff2617; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">LI: I am learning the process of the Chromatography and use this to assist solving the crime.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Aim: To use Chromatography to distinguish which pen was used in the ransom note.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Hypothesis: When we did the experiment I thought that the sharpie would be the pen she use to write.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Equipment: Beaker,ransom note,filter paper,hand,lens,masking tape,straw.

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Results:

<span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">A.

Chromatography is a technique used for seperating mixtures. In all of the variations of Chromatography, a substance is placed onto or into a medium and then a solvent passes through the test substance, some of the test substance may be attracted to the solven and follow it up in the medium. Different types of molecules are transported different distances, causing them to seperate. In these activities, filter paper is the medium, solvent is the solvent and black ink is the test substance. Chromatography is used in crime labs to seperate the components of 'clue' substances such as blood, ink or other mixtures found at the scene of a crime. Chromatograms of these clue substances are then compared with those of the suspected sources.

__** Chromatography Today's date: Tuesday 10th May 2011 **__

__** L.I **__I am learning the process of the chromatography and use this to assist with solving the crime.

__** Aim: **__To use chromatography to distinguish which pen was used in the ransom note.

__** Hypothesis: **__ I think that ......................because..............

__**Equipment**__ - Beaker, felt pens, ransom note, filter paper, water, hand lens, masking tape and straws.

__**Method:**__

1. Gather samples of pens. 2. Draw a line across a strip of filter paper, 1-4cm from the bottom. 3. Attach to straw with masking tape. 4. Put filter paper in beaker, making sure the ink is at least 1-2cm above the water. 5. Observe. 6. Remove filter when water has travelled about 3/4 of the way up the strip. 7. Compare results with the ransom note results.

__**Results -**__ A- sharpie did nothing,B-Felt pen made many different colours green,blue and purple, C-Blue pen did nothing,D-Bic felt whent black and runnie.

__**Conclusion -**__ We found out that the green felt pen was the same as the writing on the ransom note and the other pens had no affect when we put it in the water.

The ___ pen wrote the ransom note because__
