**Teacher Comment: I love your title Kennedy it is fantastic and really stands out!. The photos down the side are effective and your topic is very relevant. Your introduction, aim and method are amazing and it is great that you have explained that you have stayed away from dancers etc because they are naturally more flexible. You have included science behind your results which is so important for your own learning. You have done an excellent job here Kennedy well done!**

**Student Comment:**

__//Thursday 12//__ __//th//__ __//May 2011//__

__//Aim://__ //To find out what substance was in each pot.//

__//Hypothesis://__

We thought the substances were:

*A- Baking Soda *B- Salt *C- Icing Sugar *D-Cream of Tartar *E- Corn Flower.

__//Method://__


 * //Put each substance into the glass on by one.//
 *  //Place the Litmus paper into each substance that is in the glass.//
 *  //Then if nothing happens with that then add the vinegar.//
 *  //If nothing happens again with that add the iodine.//

__//Results://__

//*A-// Corn Flower. //*B-// Salt <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">//*C-// Baking Soda <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">//*D-// Icing Sugar <span style="font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">//*E-// Cream of Tartar

REFLECTION: I learnt how to tell different substances apart from each other and to know what they are.

<span style="font: normal normal normal 18px/normal Arial; letter-spacing: 0px; line-height: 27px; margin: 0px;">**Chromotography experiment.**

<span style="font: normal normal normal 18px/normal Arial; letter-spacing: 0px; line-height: 27px; margin: 0px;">**Lesson One - Paper Chromatography**

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">LI: I am learning <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">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.

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Chromatography Today's date: Tuesday 10th May 2011**

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**L.I** I am learning the process of the chromatography and use this <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">to assist with solving the crime.

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Aim:** To use chromatography to distinguish which pen was used in the ransom note.

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Hypothesis:** I think that ......................because..............

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Equipment** - Beaker, felt pens, ransom note, filter paper, water, hand lens, masking tape and straws.

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Method:**

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">1. Gather samples of pens. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">2. Draw a line across a strip of filter paper, 1-4cm from the bottom. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">3. Attach to straw with masking tape. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">4. Put filter paper in beaker, making sure the ink is at least 1-2cm above <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">the water. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">5. Observe. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">6. Remove filter when water has travelled about 3/4 of the way up the strip. <span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">7. Compare results with the ransom note results.

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Results -**

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">**Conclusion -**

<span style="font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">The ___ pen wrote the ransom note because__

<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://__ //I think that it was the green felt pen because the writing was green.//

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

__//Results://__ //There were four different pens, three of them were black and the fourth was green. When we tested them out in the water.// __//Monday 2nd May 2011//__

//I chose green because it was easy and fun to do the experiment and try and succeed what we were aiming for.//
