=Term 2 reflection.=

==Inquiry. This term we did our topic and inquiry on Take action for water for this we had to find out about the rivers, streams,oceans and lakes and how us humans effect them.We went up to Mt Holdsworth and looked at the streams and rivers there then we went down to Papawai stream.Mt Holdsworth streams and rivers were really clean and had not got polluted by humans but the Papawai stream was the complete oposite it was really dirty and had rubbish in it.We also learnt about native fish and Aquatic animals int he rivers.==

==Did you know eating tomatoes, ketchup, tomato sauce and tomato paste-topped pizza more than two times a week can reduce the risk of cancer by 50%?This is because of the lycopene in it .Most people think Tomatoes are thought to come from Italy but they actually comes from Mexico ,they must have lots of tomato sauce in their country but no actually China and U.S.A produce the most tomato sauce per year a whopping 37,992,610,241 kilograms or 41,879,684 tonnes of it per year.==

==So next time you go to the supermarket You have to go and get some tomato sauce because it’s really good for you and you can use them for things such as red paint or you could also use it for fake blood to scare people.== ==Oh one last thing before I go to the supermarket and by some tomato sauce I’ve got one more really funny joke for you.Q: How do you fix a broken tomato? A: Tomato paste! and remember it’s gotta be good for you.==

==Writing. This term for writing we did expositions and we also did fun writing.Fun writing is when you find a digital learning tool on the internet and write a story with a partner and guess what it's fun.I wrote a story with my partner Lachlan about inventors creating time travel and giant monkeys.==

=Science fair.=

This year I did my science fair on why apples go brown. I came first out of the year 7s and 8s.

 * How do you stop apples going brown? **


 * I really like apples so when I cut them up and put them in my lunchbox,I’m really excited at lunch time until,I find out the apple has turned brown!!!! So I decided to find out why they turn brown and also how to stop them going brown. **

Research

 * When you cut open an apple the apple goes brown, Apples go brown because, when air touches the apple it releases an enzyme the enzyme reacts with oxygen this is also a chemical reaction.The enzyme along with the oxygen turns the apple brown, when cut. **

Hypothesis

 *  If the apple slice has enough lemon juice on it I think this strategy will work | **
 * best this is because the lemon juice has acids in it and will cause a chemical reaction and cause the apple to stay white and not turn brown.The worst apart from the obvious of leaving it out on its own I think will be leaving it in water this is because the water Will trap oxygen like in a river and this will go on to the apple and turn it brown. **

Method

 * Materials **
 * Pacific Rose apple, **
 * 4 bowls and a board, **
 * 5 teaspoons of lemon juice, **
 * 3 teaspoons of salt, **
 * knife,water,cling wrap, **
 * Fridge. **


 * 1.Cut the Pacific rose apple make sure it’s non bruised apple into 6 slices and put them in the fridge for 10 minutes. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">2.Get 4 bowls and get salt, lemons,fresh water, cling wrap and a board to put one slice on. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">3.Place a slice of apple in each of these bowls. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">4. Make sure at least one side of the slice is submerged under the water or lemon juice. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">5. Get 3 teaspoons of salt into a bowl put a cup of water with the salt and 5 teaspoons of lemon Juice into another bowl.Also get a bowl of room temperature water. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">6.Quickly get some cling wrap and wrap a slice of apple in it and lastly get an apple slice and leave it out by it self and put the slice of apple in the bowl of water. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">7.After an hour take the apple slices out which apple slice is the most brown,are there any that are still white. **

<span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">Results

 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">The lemon juice wasn’t the best solution but the salt water instead which was surprising.I was right though with the worst which was of course the apple with nothing on it and 4th was what I also guessed the apple slice in fresh water. **

<span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;"> Conclusion

 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">So when you want to preserve an apple without it going brown the best solution is to get a bowl with 3 teaspoons of salt diluted with 1 cup of water. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">What do you think will happen. **
 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;"> I think to stop the apples going brown I will have to put in lemon juice I think this theory will work best. **
 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">I think the apple on its own will be the worst but after that I think the one in freshwater. **


 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">The reaction can be slowed or prevented by inactivating the enzyme with heat (cooking), reducing the pH on the surface of the fruit (by adding lemon juice or anotheracid, reducing the amount of available oxygen (by putting cut fruit under water or vacuum packing it), or by adding certain preservative chemicals (like sulfur dioxide). On the other hand, using cutlery that has some corrosion (as is seen with lower quality steel knives) can increase the rate and amount of the browning by making more iron salts available for the reaction. **


 * 1) <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">Cut and keep the apples under water. This prevents air from reaching the iron. But it may cause some vitamins to leach into the water.
 * 2) <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">Rub the cut apples with lemon juice. The acid in the lemon juice stops the polyphenol oxidase from working.
 * 3) <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">If you're making apple pie, you can dip the apples in boiling water for a few seconds and take them out. This is called blanching, and it stops the browning enzyme.
 * 4) <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">You can add some salt to the apples; the salt stops the enzyme. Do this if you don't mind the salt-and-sweet taste that will result.
 * 5) <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">Keep the apple pieces in an airtight jar, or wrap them in cling wrap very tightly. This also stops air from getting to them.
 * <span style="font-family: 'Trebuchet MS'; font-size: 16px; text-decoration: none; vertical-align: baseline;">And finally, the method we like the most. Turn your apple into apple juice. The iron oxide gives it the special golden-brown colour, and it's a tastier way to consume an apple! **

=Cross country.=

I came first at the Greytown school Cross Country,First at Kahutara and I am doing the Regional Cross Country on Thursday Which is in Wellington.
These are my results for running round the school.

Fifth time 7:15
