Sessions on how changes in climate may affect Scotland's sealife, and how to construct an electrical circuit which incorporates a buzzer, are just two of the interactive workshops at this year's INEOS Science, Engineering and Technology fair at Grangemouth.
More than 1,850 P7 children from 52 schools - including all the primaries in the Falkirk Council area - are attending the annual event, which opened this week and runs until March 17.
A spokesman for INEOS said: "As an industry that uses science and technology every day, it is important that we enthuse the next generation to take up these subjects at secondary school."
Other workshops include the K'nex design challenge, in which pupils have to understand balancing forces as they construct a model of the UK's largest mobile crane; "bang or no bang", in which pupils become contestants in their own game show as they explore the world of chance and uncertainty; and "elemental", which investigates the properties of slime, putty and chocolate cakes.
The 2009 SET fair is supported by INEOS, Global Science, the Scottish Government and Falkirk Council and is part of the "My Future's in Falkirk" economic development initiative.
