Research
• Iron is a heavy, magnetic, metallic element
that is present in very small quantities in the
blood and is the 4th most abundant element
in the Earth’s crust. Iron can be found in
your blood as well. Cheerios help reduce
Cholesterol that is also found in the human
body. Iron also can be found in cereal. Iron
is found in animal and plant foods, but in
different forms. Iron is a mineral that is
found on the Science scale of minerals,
compounds, and elements.
Hypothesis
• We believe that the brand of the two
cereals would make a difference in the
amount of Iron in the cereals that are being
experimented in our project. We believe
this because, since one cereal is generic,
and the other is not, the companies may
use different ingredients that will affect the
amount of Iron in each cereal, also, one of
the cereals have a honey-flavored coating,
that makes the cereal sweet, the other
cereal (the generic brand) doesn’t,
therefore, the amount of Iron will differ.
Procedure
• First, we pour cereal out into coffee filters, and
put the coffee filters onto the balance scale, to
measure the amount of cereal in grams. Then,
after measuring the cereal, we smash it with tin
can to make the cereal into grain-sized bits. After
smashing the cereal, we put the bits into 2
different bowls (put the different brands into
different bowls, DO NOT combine cereals). Next,
you add water to the cereal bits, make sure that
the bits are covered with water. After cereal is
covered with water, stir continuously with a
magnet.
Observations
• As we were observing the experiment,
we encountered that the generic brand
had more Iron than the name brand, vice
versa.
Conclusion
• In conclusion we had discovered that the
name brand cereal has less Iron than the
generic cereal.
