**Teacher Comment: What a fantastic invention Jarrod well done! What a shame the companies didn't give you a ball figure price for the tyres. Next time maybe you could email some companies over seas and see how much they would charge to produce your tyres. This would have been interesting for you to see and this is also what would need to happen if you wanted to go ahead with you product. Great work though Jarrod keep it up.**

**//Technology//**

__Introduction__: I have chosen an invention that will help people be safer on the roads. It is a tyre that warns you when it is becoming unsafe to drive on. This will help people know when they need a new one. These tyre’s will be good for police to easily track down the illegal ones on the road. It will make tyre companies good money cause people will make sure they always have good safe tyres on their vehicles. It could save them money too as they won’t be fined from the police if they are legal.

__Aim__: My aim was to produce a tyre that will warn people before they become unsafe and illegal.

__Question:__ Will my invention help people in the future? Would the police like them? Will my product be a success?

__Sample Materials/equipment:__
 * 1-2 tyre’s
 * Something to cut the rubber.
 * Red spray paint or paint (that won’t come of)

__Success Criteria:__
 * I will have to find out what the red dye that’s put on the tyre’s are made out of.
 * I will have to try to cut into a tyre and this will be a challenge because there is metal in a tyre and I will have to use alot of different tools to cut into it.

Prototype 1: This prototype is made out of red rubber, we drilled out the center to make it look like a tyre and then we painted it black and scraped it out to show the red underneath the black paint.


 * **What was good about prototype 1** || **Things I need to work on** ||
 * It was made out of rubber like a real tyre. || Making it a real tyre or close to one. ||
 * I showed what would happen if your tyre got worn out. || I need to show were the red strip would be on the tyre. ||

Prototype 2: This is made out of an old tyre called a cross ply tyre. My dad cut it to make a cross section of the tyre. We painted a red layer underneath the tread just under the illegal limit in nail polish.


 * **What was good about prototype 2** || **Things I need to work on** ||
 * It’s close to a steal belt tyre || Next time I need to work on doing it on a proper tyre which is a steel belt tyre. ||
 * Prototype 2 was clearer to see in side the tyre. || I need to make a different red because you can’t see the red on this one well. ||
 * It was easier to see where the red limit would be. || I need to make it more bigger next time. ||

Final invention: This is made out of a real tyre that has a steel belt in it. We painted in nail polish and a little bit of red paint where the red limit would be. This was part of a real tyre so the red limit was painted a better red as the last prototype was too dark and you could hardly see it.


 * **What was good about my final version** || **If I made another one what could I make better.** ||
 * It was a real tyre that I had used. || I could have used a whole tyre instead of a piece of one. ||
 * I could see the red nail polish clearer because we added red paint over it. || Instead of nail polish to show this red strip I could have layered it with red rubber. ||
 * It was bigger than prototype 2. || The prototype could have been labeled to show what materials are used within the tyre. ||

__Marketing:__ Who will I sell this product to? I would sell my invention to a tyre company first such as Tyre master, Bridgestone/Firestone or Dunlop. I would probably sell it to the big tyre companies that people go to more often and then the little ones.

What will I call my invention? I am going for a name that people will see and will remember. When it wears down it shows the red strip and when this happens it is at it’s illegal limit. So I will simply call them ‘Red Limits’.

What price could I sell my invention for? No price can be put on this product until it is made as I need to know how much it could be made for first. There are no tyre manufacturers in New Zealand so I couldn’t speak with them to find out how much it would cost to make. I did do a few quick survey’s though on six people in my class. About three out of six were willing to buy my invention for $450, another person said $200-300 and the last person said $100-200.

How will I advertise it? I would put my product on big posters and put them around all tyre shops. I would put it all over T.V as well, e.g. on the news and in the adds. I will make brochures and put in the newspapers where everyone can see it because I want as many people as possible to see them and want to buy them.

Where would I sell the red limit? After doing my survey most people suggested Tyremaster would be a good place to start my invention, this would be because they know that my dad works at Tyremaster. I spoke to his boss Ian about my tyre and he thought it was a great idea. I would also try to contact as many other tyre companies around New Zealand.

__Feed back:__ After getting people to do the survey a couple of people thought that I should maybe make the rubber go green first, then orange and then red. So that when you see orange it warns you to keep an eye on the tyres and check them regularly before it gets down to the red.

__Product development:__ Some things I was thinking about... Having come up with this idea of a tyre with a layer of red rubber just under the illegal limit, the first Questions I asked myself were:

1. What will I use for the red strip? 2. What am I going to do for my prototypes and my final version?

Some ideas of what I could make the red strip out of: For the strip on the tyre I thought of making it with red paint or red spray paint (thin spray) because my dad has red paint and spray paint in the garage. Also I could use some of my mums red nail polish for it.

Some ideas for what I could make my prototypes and the final version: I was thinking of getting a tyre and getting my dad to cut it into a cross section of a tyre and then using the red paint and putting that on the tyre showing where the red strip would be when it became illegal. I was also thinking about getting something round and painting it red, and when the red paint dried I could put a layer of black paint on top. After that I could scratch some of the black paint so then it shows the red underneath, which would show you what would happen if the real tyre got warn out.

__Conclusion:__ It’s been fun finding out and making my own invention of a tyre and seeing how much money I could get from this. A highlight of making and processing my invention would probably be making my prototypes, final version and painting my science fair board.

__Acknowledgements:__ My dad (Joe) for helping me with getting all the equipment I needed. My mum (Ann) for printing every thing off for me. Tyre master and Ian the boss of tyre master for letting me interview and ask him questions. Some of my mates in my class for doing my survey’s

Thank you guys so much for helping me!

__Aim:__ To find out and name what the 5 substances were.

__Hypothesis:__

Icing sugar-sub D Baking soda-sub A Cream of tartar-sub C Salt-sub B Cornflower-sub E

__Method:__

We added water to most of the substances and then tested them by putting blue and red litmus paper, iodine and vinegar.

__Results:__ Icing sugar-sub D Baking soda-sub C Cream of tartar-sub E Salt-sub B <span style="color: #053df5; font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Cornflower-sub A

<span style="color: #053df5; font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">__Reflection:__ <span style="color: #053df5; font: normal normal normal 13px/normal Helvetica; letter-spacing: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;">Most of our answers were wrong because we only got 2 right. So we got 60% right.

__wednesday 11th may__ <span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Chromatography

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__LI:__ I am learning the process of the chromatography and use this to assist with solving the crime.

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Aim:__ To use chromatography to distinguish which pen was used in the ransom note.

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Hypothesis:__ I think that the pen is going to be D because its sort of green and the righting is green.

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Equipment:__ beaker,

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Method:__ <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">1. Gather samples of pens. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">2. Draw a line across a strip of filter paper, 1-4cm from the bottom. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">3. Attach to straw with masking tape. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">4. Put filter paper in beaker, making sure the ink is at least 1-2cm above <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">the water. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">5. Observe. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">6. Remove filter when water has travelled about 3/4 of the way up the strip. <span style="color: #0000ff; font: normal normal normal 13px/normal Arial; letter-spacing: 0px; line-height: 19px; margin: 0px;">7. Compare results with the ransom note results.

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Results:__ When we did the experiment the first one was not right it turned blue/purple. the other two were not doing anything they were just staying black but the last one was correct and we found what pen it was.

<span style="color: #0000ff; font: normal normal normal 12px/normal Helvetica; letter-spacing: 0px; margin: 0px;">__Conclusion:__

The BIC felt pen wrote the ransom note because when we put the strip by the water it went sort of blue and so did the note.

__Thursday 5th may__ Explanation: __<span style="font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">of gravity water __

<span style="color: #0000ff; font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">When me and jack did the second science experiment we filled up the cup and put the piece of card board on top and pushed hard on the card board then haled it there for about five seconds and then we turned it over the card board stayed and no water could get out of the cup our experiment was a success. <span style="color: #ff0000; font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Today it was pretty easy because I did it on my first go and it was a success. <span style="color: #0000ff; font: normal normal normal 14px/normal Helvetica; letter-spacing: 0px; margin: 0px;">

tuesday 3rd May <span style="font: normal normal normal 18px/normal Helvetica; letter-spacing: 0px; margin: 0px;">Spinning top experiment: <span style="font: normal normal normal 18px/normal Helvetica; letter-spacing: 0px; margin: 0px;">First you cut a piece of card board in a circle using a cup and then colour it in red,blue and green then put a hole in the middle and then you put a pencil in the hole and then spin it. On our spinning top the colours turned yellow ish on the first one and the second one went white. <span style="color: #ff0000; font: normal normal normal 18px/normal Helvetica; letter-spacing: 0px; margin: 0px;">it was easy because I have made one before. <span style="font-size: 14px; font: normal normal normal 18px/normal Helvetica; letter-spacing: 0px; margin: 0px;">
