    Wood conservation - the Mary Rose

    The Mary Rose is a wooden Tudor warship that sank off Portsmouth in 1545. While on the sea bed, most of her hull became covered in silt, which effectively sealed it and the artefacts it contained in anaerobic (air-free) conditions and preserved them from decay.

    Colourimetric determination of copper ore

    In association with

    An ore is any rock from which a metal may be extracted. To decide whether an ore is worth mining it is necessary to find out how much of the useful mineral it contains. This experiment illustrates an example of how this might be done.

    Crystal Sizes

    The activity relates to the process of igneous rock formation by the cooling of magma.  It can be used to illustrate how the rate at which molten rock cools affects the size of the crystals that form within the solid rock – rapid cooling producing small crystals, slower cooling producing larger ones.
