**Teacher Comment:** Well done Sam, you seem to have put a lot of effort into your science fair project. Great hypothesis which is backed up with reasons why you thought this. Great to see you conduct your experiment more than once to ensure your results are accurate. Nice explaining how you worked out the arrows speed also. Great use of graphs to display your average results. Did you carry out any research as to why the material is the best to make an arrow out of or did you just make some guesses? Your arrows needed to be the same length though as this would definitely affect your results. Overall a good effort Sam.

**Student Comment:** I think I done well but I need to work on getting it done earlier so I don't rush it. The thing I think I done best was working out the km/h by just using maths. I should have done this by my self but I had some people helped.


 * __CSI REFLECTION:__**

We had a turn in the science lab and we had to find out what is in the jar we were not aloud to taste the things, so we had to find using science, so we found this out by using some litmus paper we found out that: -cream of tartar turns blue litmus paper red. -salt is a alkaline, that is why they turn red litmus paper blue. -cornflour and sugar are neutral and don't affect litmus paper.

And we all so found out that: Iodine changes from yellow-brown to blue-black with cornflour. backing soda fizzes when mixed with vinegar.

__**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 I checked my fingers.

EQUIPMENT Pencil, paper, sticky tape

METHOD- 1.Rub in the side of the pencil lead back and forth on a sheet of paper to build up the black area large enough to take 10 prints. 2.Prees one of your fingers firmly onto the black. Place the sticky side of a piece of tape over your fingertips. (You may need help for 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 archers, loops or whorls.

My right thumb is a loop and my left is a arch and both of my index is a whorl and my right middle finger is a whorl and my left is a loop and my ring fingers are loops and my little finger is loops.
