Use a magnet to test for the presence of iron in breakfast cereals

Suitable For

Grade 1



Time Required

What’s it about?

Iron is a mineral essential for life. It is present in every living cell and is necessary for the production of ‘hemoglobin’, the protein in red blood cells that carries oxygen to the various parts of your body. Iron can be found in many types of foods, as well as in breakfast cereal, as you will learn in the following science experiment:

Topics covered

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

Crushing the cereal into a fine powder in this science experiment allows the traces of iron to break away from the rest of the food particles and stick to the magnet. The unfortified cereals contains too little iron to be attracted to the magnet, but the tiny white edible iron particles from the iron-fortified cereal, get stuck at the tip of the magnet when dipped into the powder.
