Archaeology is about reconstructing the physical past to obtain an understanding of how different civilisations and cultures have evolved over time. In this album, archaeologists from the British Museum explain the scientific processes involved in the discovery, investigation and interpretation of a variety of artefacts, such as skeletons, coins, textiles and metal artefacts unearthed at sites such as the famous Iron Age burial at Sutton Hoo, and Tell es-Sa'idiyeh in Jordan. The album also reveals how amateur archaeologists who use metal detectors contribute to creating a picture of ancient societies. This material forms part of The Open University course SA188 Archaeology: the science of investigation.

The 1967 collapse of the Silver Bridge over the Ohio River was an engineering mystery and a human tragedy - 46 people died. Why did a suspension bridge built to last a century not make 40 years? Built in 1928, it was a slimmer version of similar bridges built in nearby Pittsburgh. The slimming down was deemed to be safe because of the use of a tougher steel and ‘silver coloured anticorrosion paint’. The tracks in this album look at the factors which led to the catastrophic failure of one of the eyebars which supported the deck, and the subsequent forensic investigation which led to the creation of the National Bridge Inspection Standards to inspect the 1 million bridges of the USA. This material forms part of the course T357, Structural integrity: designing against failure.
