Thursday 14th July 2011 I am glad you are enjoying you science work Levi, I also found it interesting that the orange wasnt the one with the highest vitamin c. Keep up the good work. Dad

**Teacher Comment:** Wow! A very brightly presented science fair Levi! Suits the topic very well. Did you come up with idea yourself or did you get it from a book? This is a very technical topic. Great to see you carried out your experiment more than once to ensure your results were accurate and not a fluke. I am surprised with your results - I would have thought an orange would have had the most vitamin c, just like you did. Great to see that you carried out some research into vitamin C and why we need it in our bodies but I would have liked to have known why Green Pepper has more vitamin C in it. You needed to discuss your results a bit more in your conclusion as well as include your scientific explanation in it.

**Student Comment:** I think I did my science fair pretty good. I had a fun time doing this experiment. It also was fun spray painting my board bright orange. I got this idea out of a science book from the library. If I was to do this science fair again I would go further with my results in it.

**We went into the science lab to do some experiments. We had 5 substances that we had to identify. To identify them we had to do a few tests. The first thing that we needed to do was make a hypothesis. My group thought that substance A baking soda B was icing sugar C was salt D was cream of tarter and E was cornflour. We had to put vinegar into the experiments because when you put vinegar into them they have different reactions for (e.g) baking soda fizzes and cream of tarter turns black. In the end none of our hypothesis was right except for one which was salt.** **All of my groups results were correct with substance A B C D and E**

__**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 .loop..and..whirl..... I think this because .i.looked..at..my...fingers..before**


 * EQUIPMENT Pencil, paper, sticky tape and magnifying glass**


 * 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 fingerprint form.**
 * 4. Using the magnifying glass compare your prints to the pictures above and try to label them as either arches, loops or whorls.**
