Apparatus Chemicals

For the demonstration, the teacher will require:

Mortar and pestle, size sufficient to contain 50 g of the cereal

Beaker (1 dm3)

Magnetic stirrer and follower (stirrer bar) coated in white plastic (Teflon or nylon)

Forceps or clean tongs

For the class experiment, each working group will require:

Mortar and pestle, small size

Beaker (250 cm3)

Strong magnet (e.g. neodymium magnet) (Note 2)

Breakfast cereal containing added iron (Note 1)
