APP for Primary Science - the Big Stink with Deborah Herridge

This Teachers TV programme shows how to use Victorian London as a topic to combine science and history at Key Stage Two. In 1858, the smell of untreated sewage from the polluted Thames in London, known as The Big Stink, led to the development of the drainage system. In her CPD workshop, Deborah Herridge shows the teachers how to recreate the stink by mixing pasta, chocolate and rice, then sets them the challenge of obtaining a clean glass of water. The groups have to decide how to separate the mixtures and choose the appropriate equipment for this from a range of sieves, filters, coffee filter papers and plastic bowls and jugs.

This activity shows how practical science activities may be set in a historical or modern world context to engage learning. She also shows teachers how practical investigation is a way of covering APP (Assessing Pupil's Progress) in the classroom.
