**Teacher Comment:** Fantastic topic Georgina, very original and something that you are obviously interested in, which would have made the investigation more exciting for you to carry out. A very nicely presented science fair board also. Great use of graphs, tables and photos to show your results and to help explain what you did. A very clear method which would be easy to follow. Well done carrying out your experiment more than once to gain an average, this helps to prove your results were not a fluke! Excellent discussion of your results in your conclusion, especially stating what you have learnt. Was there any more science behind your experiment at all? A superb effort Georgina, well done.

**Student Comment:**

I think I did a good job with my science fair. It was fun to do, and a great experience. I think that I could have used better photo's for my board as some of them were blurry. I think I presented my science fair well and my graphs are all quite easy to read. If I did my experiments in a different order for example 60psi,50psi,40psi,30psi,20psi,10psi, 60psi,50psi,40psi...... it may have made my results more even.

__**Science Reflection**__

This week is science week so we went to the science lab to do 25 experiments. My favourite experiment was the potato one. What you do is have half a potato and to small straws. First you hold the straw without covering the top and hold it about 10cm above the potato, then jam it down into the potato and take it out. Now use the other straw and jam that one in too, but this time cover the top up. Take the straw out and look in it, there should be some potato wedged in there! This is because when you cover the top up you block out all the air getting in the straw which makes the potato stay in the straw!

Yesterday we went to the science lab to do some more experiments. We had to identify 5 substances and then figure out what it was out of: Cream of tartar, Baking Soda, Icing sugar, salt and cornflower. We guessed that A is icing sugar, B is salt, C is baking soda, D is cream of tartar, and E is cornflower.

Here are our results. Substance A was cornflower. B was Salt, C was Baking soda, D was icing sugar, E was cream of tartar.

We found out this by doing the experiments here is how we knew what they are: Cream of tartar turns blue litmus paper red. Cornflower and icing sugar don't effect litmus paper. Baking soda and salt turn red litmus paper blue. Baking soda fizzes when mixed with vinegar. Iodine changes yellow brown to blue black with cornflower.

We got some of our hypothesis correct but not all of it.

__ 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 are Mainly loop on my left hand, and arch on my right. I think this because I have studied them with my eyes. **

** EQUIPMENT Pencil, paper, sticky tape **

** METHOD **

** 1. Rub the side of a pencil back and fourth 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 fingertip form. ** ** 4. using the magnifying glass to compare your prints to the pictures above and try to label them as either arches, loops or worls. **



I found that I have 5 loops and 5 arch here are all my results:
 * Conclusion**


 * Thumb Index Middle Ring Little**

Loop arch arch arch loop loop arch loop arch loop
 * Left** **Left** **Left** **Left** **Left**
 * Right** **Right** **Right** **Right** **Right**

I think my results turned out okay and most of them are easy to read.
