Iron is important to us for tons of different reasons. We can make thousands of useful objects from it, and it's even the main ingredient in making steel (made from iron and carbon).
As it also turns out, humans need iron to live. Iron is an important part of a substance called hemoglobin, a chemical in our red blood cells that helps transport oxygen through our body. Without iron, our bodies can't manufacture enough red blood cells. This leads to a disease called iron deficiency anemia.
To make sure we're getting enough iron, some food manufacturers started adding tiny amounts of extra iron into their producs (Yes, this is the same iron we make paperclips from!). This is especially common in breakfast cereals with added nutrients. In this experiment, we're going figure out which breakfast cereals have extra iron added and which do not.
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
