**Teacher Comment:** Well done Shelby, a nicely presented Science Fair. Excellent hypothesis and stating why you thought that would happen. A fantastic concise, clear method that is easy to follow. How did you measure which was the most effective? You needed to carry out your experiment more than once to ensure your results are not a fluke - this is the only thing that lets your science fair down! Great to see you carry out some research into how stain removers actually remove stains, this added depth to your conclusion. Nice use of photos to help explain what you did also.

**Student Comment:** I measured which stain removal worked best by observation, I think I should've carried out my experiment more than once to get a more accurate result, but I did leave the experiment a bit too late to be able to do it more than once.In the end I am really happy with how my science fair turned out, it is a very common experiment to do and it is my first time doing a science fair so I had no idea how it would turn out. I am proud of myself and think that I did a really awesome job.I think that I could've done a nicer job with presenting it on the board, but I think more about what I have written rather than how I presented it. Although I do think that I chose really good colors that work well and make my science fair stand out. Thank you Miss Crone for the comment and giving me some tips for next time.

Shelby, :D




 * Science**

Well it is science week this week,so we went into the science lab to do some cool experiments. My favorite was the one where you have to tie two pieces of string onto a spoon,then you wrap the two free pieces of string around your two index fingers and put the tips inside your ear,let the spoon dangle freely in front of you and gently tap against the table and it makes a sound like a door bell,or you could say it was a bell chime. This happens because of the vibrations that come from the spoon when it hits the table,they run through the pieces of string,this is only able to work if the strings are pulled tight.

We went to the science lab,and did an experiment on how to identify which substance was which,we had 5 substances to figure out.The first thing that we had to do was make an hypothesis,our group thought that A was icing sugar,B was salt,C baking soda,E cornflour and D cream of tartar.We put vinegar and water in which one we thought was baking soda because when you do this it will fizz.We also had red and blue pieces of litmus paper, if we put blue litmus paper in the cream of tartar it will go red.If you put red litmus paper in bicarbonate of soda and salt it will go blue this happens because they are alkaline. Our group only got a few of the substances correct,because we were really confused at the beginning on how to do it but in the end we pulled it together and I guess it payed off.

__ **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 a mixture of loops and whorls and on some of them just plain loops. I think this because when I look at my fingertips and at the picture they look the same.

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 fingertips firmly onto the black.Place the sticky side of a piece of tape over your fingertips.(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.

Conclusion My left hand were technically half and half two of them were loops another two were whorls and my thumb is an arch. My right hand were the same as my left my thumb is an arch the other four are loops and whorls. My hypothesis was wrong I thought that that I had no arches but both my thumbs were.
