Well done Ruby this was a great Science Fair. Your project was well structured and was easy to follow. Your results were presented well, I'm glad you managed that double bar graph! It is good that you did some research and included this in your results. It is alway important to include a bibliography on your display. Overall Well done!
 * Teacher Comment:**
 * Student Comment:** I think that my science fair was good and was easy to do because the topic was rather simple and the experiment was easy to do. I added in extra information on PEFR. But I could have had a better layout on the board. I could not find any information on why I got the results I did. I think that my layout was easy to read and and I managed my time well through out the time limit. I didn't manage to get a bibliography. Overall I think I did an good job!!!


 * Aim:** Does age and gender affect peak peak expiratory flow rates? (PEFR)


 * Hypothesis:** I think that the results will show that the lung capacity between male and female will be similar but as the human gets older the lung capacity will get worse and as the age goes up the lower the scores will get.

 * Method:**
 * 1) Take the Peak flow meter

 * 3) Make sure pointer at zero
 * 4) Get person to stand up to do the test
 * 5) Get your first person to take a deep breath
 * 6) Person places peak flow meter in there mouth with there teeth either side of the card board mouth piece and lips sealed around it
 * 7) Person then blasts the air out of there lungs as hard and fast as they possibly can
 * 8) Write down the measurement
 * 9) Person then repeats this twice
 * 10) There age and gender are also recorded

A Peak flow rates measures how fast you can blow air out of your lungs after taking a deep breath. The measurement is a number, this is measured in liters per minute. Scientists who study aging say PEFR’s (peak expiratory flow rates) decrease with age. And I am trying to find out if age and gender affects peak flow.

I tested the peak flow rates in age groups the first age group I tested was 10-25 years of age. The first girl I tested was 12 years old and her best score was 400 liters of air. The first boy I tested was 12 years of age and his score was 375 liters of air. And the final male I tested was 23 years of age and he scored 603. This age group was one of the middle age groups. The first female I tested was 36 years old and scored 330. And there was then another male that I tested and he scored 573. There was then another age and there was then another male who was 55 years of age and he scored 590. The last male I tested was aged 50 and scored 530. One of the females I tested was aged 48 years and scored 469. The final female I tested was aged 57 years and then scored 500.
 * 10-25 years of age**
 * 26-40 years of age**

The next age group I tested was 41-55 years of age. The first female I tested scored 370 liters of air. The next person I tested for this age group was a male and he scored 650 liters of air.And there was then another male that I tested and he scored 573. There was then another male who was 55 years of age and he scored 590. The last male I tested was aged 50 and scored 530. One of the females I tested was aged 48 years and scored 469. The final female I tested was aged 57 years and then scored 500.
 * 41-55 years of age**

The first male I tested was aged 66 years of age and he scored 495 litres of air. The second male I tested was aged 573. The third and final male I tested was aged 70 and scored 664.
 * 56-70 years of age**

The final age group I tested was 75 years and above. The first female I tested scored 260 and was aged 260. The second male I tested was aged 75 years of age and scored 545.
 * 75 and above**

Some people find it useful to help manage there asthma with a Peak flow rate meter. A peak flow meter is useful to measure and keep track of asthma. Peak flow rates change with age but the best score was done by a 70 year old and he scored 664. I was supprised with this result because I thought a few of the youngest people would score the highest. Although the lowest score was scored by a Lady at 74 years of age and she scored 260. So half of my hypothesis was right, because I predicted that the higher the age got the lower the scores would get.

From my tests it has been proven that males have a better peak flow that girls, the average males peak flow score was 509 and the girls scored 375.85. My hypothesis was not quite right because I thought that the score between the male and female was simalar but they was actually quite a big difference.
