__** Introduction **__ I chose this science experiment because I am interested in finding out much iron is in my cereal and can I see it, most breakfast cereals add metallic iron as a health supplement, so I am checking to see if the brands of cereal have iron specs in them to see if they actually have iron in the cereal.

__** Aim **__ To find out how much iron is in 6 cereals I have chosen?

__** Hypothesis **__ I think the cereal nutri-grain will have the most iron because iron is a health supplement and they advertise that it is a iron man food and I think the other cereals will be some where close along the lines. Personally I think that frootloops will come last out of all the cereals because they taste like lollies. __**Methodology**__ 1.Put the 50g of cereal in a blender and let the blender make the cereal very fine. 2.Pour enough water into the blender to make it soupy ( keep the cereal in the blender) and mix it until the cereal and water is mixed together ( Don't worry about putting to much water in because iron does not dissolve.) 3.Pour the mixture into a dish and celotape the magnet to the pencil and put the pencil in the plastic zip lock bag and wrap it round the pencil tightly. 4.Stir the pencil in the mixture for 2 minutes ( make sure you stir it on the bottom because the iron will sink to the bottom.) 5.Lift the pencil out after 2 minutes then wipe it on filtered paper. 6.Look thought a magnifying glass to see the iron more clearly. __** Equipment **__ one cup of 6 different cereals. 1 magnet 1 pencil scales blender/food processor large flat dish filtered paper ** __Results__ ** My results are Nutri-grain had the most iron because it appear to be the most visible.The milo and the frootloops, I found it hard to find any traces of iron maybe this was due to the colours. The weetbix was also hard to see because of the fine grains of weet. The just right and corn flakes had a few tiny specs of iron.


 * __Conclusion__ **

My hypothesis was wrong I am surprised by this result because I thought that nutri-gran would have the most. This experiment was interesting because I wondered if I would actually see the iron, to my surprise there was iron but not as big as I imagined. I feel this experiment is not very accurate way of measuring the amount of iron.

weetbix corn flakes

this was not a very accurate frootloops was by far the hardest to see the iron due to the colours

weetbix was hard to see as well because of the fine grains

some cereal need more water than others
