Great Science Fair project Maddie, I'm sure you will be thinking twice before drinking fizzy drink. Your Science Fair is easy to follow and well structured, you have included some good research (remember to include a bibliography when using research). In your explanation you explained about natural sugar and refined sugar, it would be interesting to know what effect natural sugar has on your glucose levels. I think I did a lot better then last year because my topic was easier to do and very easy to research on. Like last year I think I should of started it earlier then I did. I think I could of done a little better and I should of wrote down the websites I got the information from. __Blood Glucose Level__

__Aim;__

How much does sugar in a soft drink effect the body?

__Hypothesis;__

I think that the Fanta will effect your blood sugar more because it is said to have more sugar then diet coke. I think that the V will come just below the Fanta even though it does have a lot of sugar in it and I think that the Coke will come in after the V because it doesn’t sound as it has as much sugar in. I think I think that the Diet Coke will have less sugar because because it is supposed to have less then normal coke.

__Introduction;__

Not many people know what actually happens to our Blood Glucose (Sugar) Levels when we drink and eat man made products. Very common man made drinks that are drunk are Soft drinks and Energy drinks. But what do they do to our Blood Glucose? How much do the affect a teenagers Blood Glucose Levels?

__Method;__

__Materials;__

1x 600 ml bottle of normal Coke

1x 600 ml bottle of Diet Coke

1x 250 ml of V

1x Blood Sugar Tester

1x Person

__Method;__

__Procedure;__


 * 1) Prick someones finger to see their blood sugar before the have eaten or drunk anything that day
 * 2) Get a person to drink 600ml a type of fizzy drink or energy drink
 * 3) Wait three quarters of an hour before checking their blood sugar (Make sure they do not eat or drink anything else otherwise your experiment will be ruined)
 * 4) Check their blood sugar six times with a three quarter of an hour gap between each one
 * 5) See how much the fizzy drink or energy drink has affected their blood sugar

__Conclusion;__

__Hypothesis__

In my test I found that I was correct with the Diet Coke. It did rise the blood sugar level but not by much unlike the Coke and the V. It only rised to 4.3 before dropping down 3.9 which is lower then it had been in the morning.

__Summary of Results__

__Have Learnt__

I have learnt from this test that you really shouldn’t have to much Refined Sugar because it is bad for you in many ways. But also how bad fizzy drinks and energy drinks are bad for your body, especially on an empty stomach. I found it interesting learning how you find out the blood sugar level and about just the Blood Sugar Levels them selves.

__Everyday Lives__

Everyday people have to test their blood sugar because of Diabetes weather it is Type one Diabetes, Type Two Diabetes or Diabetes of Pregnancy.

__Done Better - Could of__

Something I think I could of done better was the tests. I think it would of been better doing a few more fizzy drinks or energy drinks just to show how bad all of them are for you. I also think I should of started my science fair earlier so that I would of had time to do a few more tests.

__How much does Refined Sugar affect the body?__

There is a large amount of sugar in a soft drink and even though the labels on the bottles or cans say a certain amount normally the companies are not telling the full truth. There are two types of sugar the good kind, Natural Sugar which is from natural products, and the bad kind, Refined Sugar which is in man made products. Natural Sugar is found in fruit and vegetables while Refined Sugar is found in soft drinks, energy drinks and many of the foods we eat.

Having to much Refined Sugar effects many important things in your body such as your immune system by minimizing the ability of your white blood cells to fight bacteria, viruses and infections.

Refined Sugar also causes depression by interfering with hormone levels and mood receptors in the brain. Refined Sugar also effects your brain by giving you a major sugar high, making you wild, before dropping down so much that they will have no energy. This is very bad for children, especially if they are at school when this happens because they will not be able to learn because they will have no energy leaving them very tired.

The most common thing sugar does is cause obesity. The reason for this is that sugar is very addicting making you want more and more which will mean you will become fatter and fatter leading to obesity.

Refined Sugar is very dangerous to humans because it interferes with the brain, effects your immune system and can also cause Obesity. With Refined Sugar being in so much these days no matter how much we watch what we eat we are still taking in a very large amount of Refined Sugar each day.

__Blood Sugar__

__Aim;__

How much does Coke and Diet Coke effect your blood sugar?

__Hypothesis;__

I think that the Coke will effect your blood sugar more because it is said to have more sugar then diet coke. I think that the Diet Coke will have less sugar because because it is supposed to have less then normal coke.

__Introduction;__

We all know that your blood sugar should only reach a certain amount but how much does fizzy drink effect a childs blood sugar? Kids love fizzy drinks and one of the most drunk fizzy drinks is Coke. But how much does coke effect our blood sugar? Is it better for a child to drink diet coke? Or is it actually better to have normal coke?

__Method;__ __Materials;__

1x 2.25 liter bottle of normal Coke 1x 2.25 liter bottle of Diet Coke 1x Blood Sugar Tester 1x Needle

__Method;__ __Procedure;__


 * 1) Prick someones finger to see their blood sugar before they have eaten or drunk anything
 * 2) Get that person to drink 600ml of drink
 * 3) Wait half an hour and then test their blood sugar to see how much it has gone up
 * 4) See how long it takes for their blood sugar to go back to the original amount
