**Teacher Comment:** A fantastically presented science fair board Sam, well done. A very clear and concise method that is easy to follow. You carried out a very accurate experiment to ensure your results are true, although you could have bettered your results by carrying out the experiment more than once. Great to see you include your samples on your board to clearly display your results. Good observations of what happened to your sample. I am glad you carried out some research to explain how stain removers work and the science behind them. Did you look at the ingredients of the stain removers you used? You could have related this back to your results to explain why you think each stain remover worked differently. Overall an excellent science fair project Sam, well done.

**Student Comment:** I think I presented my science fair really well, although there were a couple of things that could have been better. Firstly I think I should have done mine a couple of times and not just once. I think my method was very clear and told you exactly what to do. Putting an example in of water and how when it rains it doesn't get uniformly wet was a great idea. If I was to do it again I would do the experiment at least three times to see if the results varied. Also I would have looked at the ingredients in the stain removers and research more about them however I think I had a very good amount of science in my conclusion that told the person doing the experiment to understand why things happen a little bit more. So finally I think I presented my science fair very good and chose an easy topic to do. I enjoyed doing the experiment and look forward to next year.

__Friday 13th May 2011__

In the science lab yesterday we carried out an experiment for our inquiry which is based on CSI. We had to find out what the samples were in each test pot. As a group we made a hypothesis. My group thought that A icing sugar, B salt, C baking soda, D cornflour, and E was Cream of tatar. We first new straight away which was salt because salt has got salt crystals and not just a powder. After making our hypothesis we smelt some of them and that was how we thought we had guessed icing sugar because of the sweet smell but after doing a test on it it did not give us icing sugar. Baking soda fizzes when you mix it with vinegar and makes a solution of foam. My group didn't need to use the iodine to test to see if it was cornflour because we had already got a result for cornflour. Using a small strip of blue litmus paper we dunked it in what we thought was cream of tartar and we got some results. We also used a red strip of litmus paper to find baking soda. I had quite a lot of fun in the science lab yesterday finding out which was which and that may come in handy one day. My group guessed some questions right and we guessed some wrong. Sam :)

Wednesday 18th May 2011 __**WALT - Identify and group fingerprints into 3 main categories : arch, loop and whorl**__

AIM - To identify your own fingerprints out of an arch, loop and whorl.

HYPOTHESIS I think my finger prints on my left hand there is one arch and all the rest on my left and right hand are all loop. I think this becauseI have looked at them and studied them with my eyes a little bit.

EQUIPMENT Pencil, paper, sticky tape

METHOD: 1. Rub the side of a pencil lead back and forth on a sheet of paper to build up the black area large enough to take 10 prints. 2. Press one of your fingertips firmly onto the black. Place the sticky side of a piece of tape over your fingertip. (You may need a friend to help with this) 3. Tape the print to the correct location on the fingertip form. 4. Using the magnifying glass compare your prints to the pictures above and try to label them as either arches, loops or whorls.

Conclusion - My results were on my left hand I had one arch and that was on my index finger and every single other finger was a loop even on all of my right hand. I think my results were really good and clear and were extremely easy to read! = )

Results:
 * Thumb: Index: Middle: Ring : Little:**


 * Left: Loop Left: Arch Left: Loop Left: Loop Left: Loop**


 * Right:Loop** **Right:Loop** **Right:Loop** **Right:Loop** **Right:Loop**
