**Teacher Comment:** A fantastic looking science board Abbey, well done. Great to see you include your reasons into why you thought of your hypothesis. A clear method that is easy to follow, but I am not sure how accurate it is with observing when the fruit turns brown. Did you sit and watch the fruit the whole time? Good use of a graph to display your results. Nice to see you relating your research into why fruit goes brown into your conclusion and trying to explain why you obtained the results you did. Overall a good effort.

**Student Comment:** I thought I did pretty well in my science fair but I think I could have put acknowledgements into my log book. My favourite part about my science fair was putting my aim, hypothesis, method etc onto my board because I am very creative and like making things look pretty. I didn't really like doing the actual experiment it's self because I had to sit and watch the fruit turning brown for over 4 hours which was pretty boring. I also didn't like presenting it in front of the class because I am very shy and go bright red when I talk a lot. But overall I enjoyed doing science fair.

__**Science Reflection**__

Today we went to the science lab to do 25 science activities. My favourite experiment was the spoon one where it makes a door bell noise. To make it make the noise you have to tie some string on to the spoon and then wrap the string around both of your index fingers and make them even. Then you have to put your two index fingers in your ears and make the spoon bang on the table so that you can hear a door bell noise. This happens because the spoon vibrates when it hit the table and you can only hear it when your finger are wraped round the string and are in your ears.

 * __CSI Session 2 Reflection__**

Yesterday we went to the science lab to do another CSI experiment. What we had to do was to figure out which substance out of A, B, C, D and E was either cornflour, icing sugar, cream of tartar, salt and baking soda.My group was Samantha, Ella and I. Firstly we had to make a hypothesis. Our hypothesis was that A was icing sugar, B was salt, C was cornflour, D was cream of tartar and E was baking soda. Secondly we had to test the 5 substances in lots of different ways to make sure that we new what was the right one in each set tube. One of the tests was we got to smell each one of the substances to see if we could recognize a smell. Another test was adding water to a substance to see what happens. You could also put vinegar into a substance and if it fizzes that means that you have found out which one is the baking soda. In the end our results were that the substance that was in the A test tube was the cornflour, in the B test tube there was the salt so we got that right. In the C test tube there was cream of tartar, In the D test tube icing sugar and in the last test tube there was baking soda. We ended up being right with our results. [not our hypothesis]

__**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 loops I think this because when I looked at my fingers they looked like loops.

EQUIPMENT Pencil, paper, sticky tape

METHOD

1. Rub the side of a pencil lead 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 finger prints form. 4. Using the magnifying glass compare your prints to the picture above to label them as either arches, loops or whorls.



CONCLUSION - My results were on my left I had one whorl and that was my thumb and all the rest of my fingers were loops and on my right hand my thumb and my fingers were loops. I think that my fingerprints came out really clear and were easy to read.

RESULTS-
 * Left hand Right hand**
 * Thumb:** Whorl **Thumb:** Loop
 * Index:** Loop **Index:** Loop
 * Middle:** Loop **Middle:** Loop
 * Ring:** Loop **Ring:** Loop
 * Little:** Loop **Little:** Loop
