Transcript of Cereal Experiment

A countless amount of brand name foods include additives which are things added during the processing and manufacturing of food products.
Additives such as sugar or caffeine can be bad for you but in other cases, some can be beneficial such as vitamins or minerals.
When nutritional supplement are added as an additive to a processed food it is required for a food manufacturer to report that information on the food label.
When you eat cereal do you ever notice the “Nutrition Facts”? Usually it would be on one side of the box listing all of the ingredients and nutritional content of the food.
Since this experiment is based on iron, I will be extracting iron from my favorite cereals and comparing the results to the daily value of iron on the nutrition facts label.

Will my results agree with the label?
Which cereal will have the most iron in it?
The experiment is done, I still have a few questions......

How do people know if they are consuming too much iron?

Why do pregnant woman need as much iron as toddlers?

Are vegetarians more prone to an iron deficiency than the rest of the population?

The Impressive
Cereal Experiment

What I knew before
Before this experiment I didn't know much about iron and with this experiment and further research I developed greater knowledge about iron. I use to think that iron was really pieces of iron until I asked my teacher. She told me that iron is an essential mineral and can be found in foods such as meats, fruits, beans and also cereal. After this I never done further research on iron until now.
Background Information
+ Iron is an essential mineral and the major reason we need it is because it helps to transport oxygen throughout the body

+ Iron is an important component of hemoglobin,

+ Iron is also necessary to maintain healthy cells, skin, hair, and nails

+ How much iron you need each day depends on your age, gender, and overall health (i.e: Infants and toddlers need more iron than adults, in general, because their bodies are growing so quickly)

+ Unlike some supplements, when the subject is iron, more is definitely not better-iron overdose can be especially toxic.

+ Iron supplements have killed young children because their needs for iron compared to an adult's are relatively low
This is what a cereal Nutrition Facts Label would look like
more Background Info..
1. Choose four kinds of breakfast cereal to test with different iron contents. You will need 250 milliliters (mL) of each cereal for the experiment.

2. Cut off the bottom of all four plastic bottles. Take off the lids of the water bottles. When you turn the bottles upside down, they will work as funnels.

3. Tape the magnet on the outside of the bottle about half way down using the duct tape. Label the bottles with the name of the cereal your extracting iron from.

4. Put 250 mL of one type of cereal in the blender and add 250 mL of distilled or filtered water.

5. Blend the water and cereal on high until you have a smooth slurry and there are no visible lumps or chunks of cereal left.

6. Carefully pour the slurry into the measuring cup.

7. Rinse the blender with a small amount of water (20 mL) and pour this rinse into the measuring cup.

8. Take the bottle that goes with the cereal you are using and hold it above the large bowl. Position it on its side with the cut-off part slightly higher than the top and rotate it so that the magnet is on the bottom side of the bottle.

9. Slowly pour the slurry through the bottle, making sure the slurry goes over the magnet and the liquid is collected in the large bowl.

10. If the slurry becomes solid and hard to pour, put the cereal back in the blender along with 100 mL of distilled or filtered water and blend. Pour the slurry back into the measuring cup and continue pouring it through the bottle. Depending on the cereal, you may have to do this four or more times.

11. After all of the cereal slurry has been poured through the bottle, pour an additional 150 mL of water through. This rinse will get rid of the cereal that is in the bottle and clean the iron.

12. Invert the bottle to get rid of water that is still in it. Remove the magnet from the bottle.

13. Leave the bottle to air-dry for 1–2 hours. Choose a location that is not windy or breezy so the bottle will not roll. After this, the pellet of iron should be visible on the side of the bottle
Evaluation of Procedure
Independent Variable:

Dependent Variable:

Controlled Variable:
The cereal with the highest percentage of iron content will most likely be the cereal with the most iron extracted from it
Four cereals including:
One cereal with an iron content of 25% DV or less

One cereal with an iron content of 25%-75% DV

One cereal with an iron content of 75% DV or more

Any other cereal you like!


Plastic, clear one liter bottles with smooth sides (4)

Distilled water or filtered (2 gallons)

Heavy duty magnet (of any type)


Duct tape

Large bowl
This cereal contains 11% of iron
This cereal contains 45% of iron
This cereal contains 100% of iron
14. Repeat steps 3-13 with the other three cereals.

15. Write your data in a data table:Name of Cereal Percent Daily Value of Iron(%) Did a Pellet Form? (Y/N) Reltiv Iron Pellet Size in cm.

16. Make a bar graph of your data. Label the left side of the graph "Size of Iron Pellet in cm". Label the bottom of the graph "Name of Cereals".

17. Analyze your data and make your conclusions.
Data Tables

+ Iron also helps our muscles store and use oxygen

+ Iron deficiency, a condition resulting from too little iron in the body, is the leading cause
of anemia in the United States.

+ Almost all the cereals you find on grocery store shelves are fortified with iron. This means
the manufacturers have added iron to the cereal, along with other vitamins, to increase its nutritional value

+ Iron is a part of that blood-oxygen delivery system, and without proper levels of iron, you
may begin to feel the weakening effects of low iron

+ When you have normal iron levels, you have enough energy in every one of your body cells.
Without enough iron, your cells produce less energy.

+ Iron is an essential mineral used to transport oxygen to all parts of the body. A slight
deficiency in iron causes anemia (fatigue/weakness), and a chronic deficiency can lead to
organ failure
Quantitative Data:
Qualitative Data:
Major Discoveries in
the field of science
The different typed of cereal
The amount of iron found in each cereal
Same water temperature,
amount of cereal,
amount of filtered water
The Question/ Problem of the experiment
The Importance of This Topic To Real Life
This cereal contains
25% of iron

-vital role in oxygen and carbon dioxide shuttling, iron helps many enzymes in the energy-generating pathways.

-Iron is also needed to make new cells, hormones, neurotransmitters, and amino acids

-many metabolic reactions and the regulation of cell growth and differentiation,

-immune activity

-proper functioning of the liver, and protection against the actions of free radicals

-Deficiency of iron can cause iron deficiency anemia (IDA)
The objective of this experiment is to come up
with a method I can use to extract supplemental iron from food to compare the
iron content of several brands of breakfast cereal.
Revisions To Procedure

+ People who don’t eat red meat, menstruating women, those who exercise a lot, and those with digestive bleeding or other blood loss issues are at risk for iron deficiency or functional anemia

+ Half the people who are overweight have impaired iron metabolism detectable on blood tests

+ Being overweight is elevating a hormone in your liver called hepcidin, which has the net effect of reducing iron absorption into your body from your digestive tract

The net result can be weight gain, fatigue, and poor thyroid function.
There are two questions that should be answered by the end of this experiment:

How can supplemental iron be removed from a processed food for testing?

How does the iron content of different breakfast cereals compare?
Based on the results..

+ My hypothesis was correct, which was..
Total Rasin Bran contains 100% of iron and
was also the cereal with the most iron
extracted from it.
-also proving that the method i used to
extract iron from the cereals worked
-The method also resulted with clear
results that were easy to compare

+ The cereals that I would less likely eat had the most iron content

+ Although Total Rasin Bran has an iron content of 100% DV, the Whole Grain in the cereal contains compounds called phytates which block iron absorption

I made this graph using the nutrition facts label from each of the cereal boxes. This way the amount of iron each cereal contains is clear and its easy to compare it to the results
This graph shows the size of the iron pellets of each of the cereals with a ruler. I measured the iron pellets using centimeters. The results were very similar to the percent daily value of iron
+ I accept my hypothesis because it was correct and I got the results I was hoping to get. It was perfectly proven with the method I used to extract iron.

+ I have no major takeaways because th experiment went very well

+ This experiment taught me a lot about Iron and how important it is

- I will be watching what I eat and remember to keep track of the iron content

- Eat foods that are iron rich but not always because too much iron isn't good for you
To improve this experiment I would......

- manage my time a little better

-gather better supplies which would've gave me better results

To limit the amount of errors in data collection I would........

-repeat the procedure twice on each cereal

-make sure the procedure is done exactly the same every time its done

-measurements are collected the same way
