**Teacher Comment:** An interesting way to look at the energy in energy drinks Britney. Good hypothesis with an explanation as to why you thought that. A very clear method that is easy to follow and very accurate and scientific. I am really surprised with your results as I would have thought that V and Red Bull would have more energy than Coke! It would have been nice to see a graph of your results as well as a table. I like how you have acknowledged the help you had from the science lab, good girl. Overall a very good science fair, well done.

**Student Comment:** I think I did very well on my science fair I was surprised with the results to. What I would do better is do a few more drinks like Demon or Mother. I had heaps of Fun doing it Miriam was really nice to work wit hand that she gave up her time to help me. She gave me the science fair idea and I was really Grateful. :)

Reflection

Today we went into the science lab to have a go at some experiments because this week is science week. It was interesting seeing how all the experiments work like the straw made holes in a potato that was my favourite, what happened was when you hold it you don't cover the top of the straw so the air can come through and the pressure of the air sent the straw in to the potato. My second favourite was the ice water and the cold water. You put one hand in ice cold water and the other in boiling water. Leave your hands in for 30 seconds the put both hands in room temperature water and that makes one hand cold and one hand warm because your hands have been used to boiling hot and ice cold water. I liked all the other experiments and it was really fun.

__Reflection__

Yesterday we went into the science lab for a second session for our CSI investigation. My group was Taylah Chontelle and I we worked well we were all fasinated of how everything worked. Our hypothosis was: A. Baking soda B. Corn flour C. Cream of Tartar D. Icing sugar E.Salt

Our Hypothesis compared to our Results was rubbish. Results:

A.Corn Flour B.Salt C.Cream of Tartar D.Icing Sugar E.Baking Soda

Overall we didn't test it well because we got 2/5 right which is pathetic.

__ 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 I think this because when i look at them from a close look i can see the loop on my finger tip.__

__EQUIPMENT Pencil, paper, sticky tape__

__METHOD:__

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 finger tips firmly onto the black. Place the sticky side of a piece of tape on your fingertip. ( You may need a friend to help you with this.) 3. Tape the print to the correct location on the finger print form. 4. Using the magnifying glass compare your prints to the pictures above and try to label them as either arches, loops or whorls.





__Results:__

All my left and right hand are loops and my hypothesis was correct.
