Held at the Ellesmere Port National Waterways Museum in Cheshire, around 60 children from a range of local schools had the opportunity to learn about
- the concepts of water density and salinity, and how they relate to the Mersey Estuary and ocean circulation through the use of flow tanks, fizzy drinks cans and food colouring
- the sizes, shapes and life of zooplankton through the use of microscopes
- the important role of phytoplankton in the marine environment and way in which zooplankton graze on them
The sessions proved a success with the children who quickly grasped new concepts whilst getting hands on with the equipment. They asked a wide range of questions on the science, what we do with the information collected and working at sea.
It was a great opportunity to bring the fascinating world of oceanography 'into the classroom', and discuss the detailed work undertaken by BODC and researchers alike.
