CSI



Learning Intentions:

 1. To become familiar with //chromatography// and be able to apply it to 'real life'  situations.

 2. To perform 'fair tests' in Science identifying substances and fibres.

 3. Identify and group fingerprintsinto 3 main categories: Arch, Loop  and Whorl.

 4. Set up and carry out Scientific Experiments following the correct process  of; Aim, Equipment, Hypothesis, Method, Results and Conclusion.

 5. Work collaboratively with peers to solve problems using the skills learnt.

Lesson One - Paper Chromatography

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 Monday 9th 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.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;">__Equipment -__ Beaker, felt pens, ransom note, filter paper, water, hand lens, masking tape and straws.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Method:

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 1. Gather samples of pens. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 2. Draw a line across a strip of filter paper, 1-4cm from the bottom. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 3. Attach to straw with masking tape. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 4. Put filter paper in beaker, making sure the ink is at least 1-2cm above <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> the water. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 5. Observe. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 6. Remove filter when water has travelled about 3/4 of the way up the strip. <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 7. Compare results with the ransom note results.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Results - <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> 1.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> The kitchen cupboard has got very damp and the labels have fallen off some <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> of the containers. From the label scraps it is found that there is:

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Icing sugar <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> baking soda <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> salt <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> cream of tartar <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> cornflour

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Use a series of simple tests and good observations to find out what substance is in <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> each container.

<span style="color: #009f00; font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;">Caution: You are not allowed to taste them! Please use small quantities.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Aim: to find out what the substance is by carrying out a series of simple tests.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Hypothesis: <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> I think that the substance in the different containers is;

<span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Substance A - Baking soda <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Substance B - Salt <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Substance C - Cream of tarta <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Substance D - Corn flour <span style="font-family: 'Comic Sans MS',cursive; font-size: 160%; font: normal normal normal 26px/normal Chalkboard; margin: 0px;"> Substance E - Icing Sugar

It is not possible to show with any certainty that two hairs came from the same person or animal. However hair can be used to rule out certain suspects or scenarios. It can also be used to corroborate (support) other physical evidence if it is consistent with the rest of the evidence.
