**Teacher Comment:** A beautifully presented science fair board Hamish, well done. Nice use of colour and photos to show what you did. Good hypothesis with a reason as to why you thought it. A fantastic method that is clear and easy to follow. Very concise and repeated 5 times, which lead to you obtaining some excellent results. Good use of tables and graphs to display your results. Interesting that the most expensive was the worst performing paper towel! Super researching into they make up of paper towels and how they actually absorb liquid. You were also able to relate this back to your results, which is great. I liked how you stated how your investigation can help us in our life. Overall an excellent science fair project, well done, Hamish. You explained your science fair well, but I sense that some of this is adult lead and a couple of questions from students tripped you up and you weren't able to answer them, make sure you have all the answers!

**Student Comment:** I think i did a great science fair but I think I rushed it a little bit because I left out my equipment accidentally but overall I think that I did pretty well and I liked that I did a good colors and I think that I did great backround pictures and the water droplets as well as doing my title in paper towels as the title and the colors and the backround relates to the topic I was doing.I think that I did a great job overall but sometimes had a few mistakes.

Wednesday 4th May Today we went to the science lab at school and we did alot of different experiments.One of my favourite experiments was a static electricity one,You had to rub a blown up balloon on our head 5-6 times and then see if little circle of paper would come and stick to the balloon.Some people would come successful and it would come and stick to the balloon.The reason those people were successful was because of static electricity and you also have to have clean and dry hair to make this work which is why only some people were successful and others were not.

Yesterday we went to the science lab and constructed some science experiments to do with **CSI.** We had to find out without tasting the substances which ingredient it was but before we could do our tests we had done a hypothesis to estimate what they could be and we thought substance **A** was cream of tartar **B salt C Icing sugar D baking soda E Cornflower. To find out what cornflower was we had to get water,vinegar and some blue litmus paper if it turned red it was cornflower Baking soda started fizzing when vinegar was added and we knew which one salt was because it looked different to all the other substances A ended as cornflower. **

__**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 arches I think this because when I tried to compare them before they looked like them and I did not see any loops or whorls in my fingerprints

EQUIPMENT Pencil, paper, sticky tape

METHOD 4 Using the magnifying glass compare your prints to the pictures above and try to label them as either arches, loops or whorls.
 * 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.) **
 * 3Tape the print to the correct location on the fingerprint form. **

__Friday 20th May__ In the end my fingerprints are 2 loop (those are my thumbs) and the rest of them were arch.It was interesting because my thumbs looked like arches but when I looked again they were loops but I was right about the rest of them though so I had a pretty good guess for my hypothesis.
