Crush the cereal with the back of a spoon, pestle or other firm kitchen utensil. Keep crushing it until it becomes a fine powder (the finer you can get it, the easier it will be to separate out the iron particles).

» Compound of iron and sulphur. The mixture is heated to form iron sulphide. The iron can no longer be separated by a magnet (the compound has new properties).

Explain the difference between mixture and compound.

Real-life application: Iron is an essential mineral. It is found in haemoglobin in red blood cells. It is needed for the transportation of oxygen from the lungs around the body. If the body does not have enough iron, it cannot make enough oxygen-carrying red blood cells. This deficiency is called anaemia. Healthy red blood cells and sufficient oxygen
is important to prevent fatigue. Athletes need sufficient oxygen supply in their blood and muscles to maximise their performance and prevent fatigue. Blood doping is a method of increasing the number of red blood cells in the body. This allows more oxygen to be carried to the muscles.
Carry out an investigation on the iron levels in different cereals and compare the results with the levels shown on the cereal packet labels.
