**Teacher Comment:** An interesting topic Braydon and a very well presented science fair, well done. Excellent use of graphs, tables and photos which clearly display your results. Well done with your scientific explanation on how you achieved the results you got. You needed to include a log book with your project that states what you did each day and when you did it. A good selection of fruits to make sure your experiment had clear results. You needed to carry out the experiment more than once to make sure your results first time were not a fluke. If you did this then you needed to state it in your method. Overall a very good science fair, Braydon, well done.

**Student Comment:** Thank you miss crone for the comment. I agree with you that I should have done the experiment more than once to make my results more accurate. Next year I will make sure that I do my experiment more than once. I also think that I could have worked on the size of the graphs so that they don't go under the title. Thanks again for the comment. :D

 * __Science Week Reflection__**

Today we went to the science lab to do some experiments. The reason that we did this is because this week is national science week. There was 25 experiments for us to try, my favourite one was one where there is three bowls of water. One with hot water, one with cold water and one with tap water. What you do is you put one of your hands into the hot water and the other one goes into the cold water. You keep them in there for 30 seconds and then you put your hands in the tap water, what happens is your hands swap temperatures. I really liked doing the experiments and I hope that we can do them again.

Reflection

Yesterday we went to the science lab to do some CSI experiments we had to find out which substance was which by doing different tests on them. This is how you would tell which was which. 1.Cream of tartar would turn blue litmus paper red 2. cornflour and suger

__** 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 whirl. **

__** HYPOTHESIS **__** I think my finger prints are the arch formation I think this because I have compared my fingerprints to the pictures **

__** 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 you with this) **
 * 3. Tape the print to the correct location on the fingerprint form **
 * 4.Using a magnifying glass compare your prints to the pictures below and try to label them loop, arch or whirl **
