A Level and IB Biology CoursesThe grounds of Leeson House provide a rich and varied range of habitats within which a wide range of Biology units can be taught including:
By travelling further afield within Purbeck the following units can be taught:-
Pond comparison studyCompare biotic and abiotic samples between several ponds within the grounds of Leeson House. Pracise identification skills using dicotomous keys, calcualte diveristy indices and compare energy transfer between each pond.
The Leeson ponds are full of life, often Great Crested Newts can be found.
Freshwater EcologyComparisons can be made between organisms found in slow and fast moving water. Indicator species are identified and several abiotic factors are recorded such as dissolved oxygen and flow rate.
The River Piddle is a safe river to study with any size group. In recent years, crayfish and marine lampreys have been caught during sampling. OCR A 3.3 PAG could be completed here as well as Edexcel B 3.3 Calculating Simpson's Diversity Index.
Marine ZonationKimmerdige Bay is one of the best places in the UK to study Marine Ecology. The double low tide each day gives plenty of time to study the lower shore. Popular studies with students include perwinkle density and limpet shell shape comparisons. OCR A 3.3 PAG could be done here with students planning their own investigation focussing on various animal species and abiotic factors.
Edexcel B Core Practical 16 looking at Limpet morphology can be completed here.
Studland Sand Dune SuccessionVisit Studland Sand Dunes to study vegetation succession. Students will carry out interrupted belt transects to investigate the environmental changes and biotic differences across the dunes. Abiotic and biotic data will be collected and groups can then travel the 10 mins back to Leeson House for data analysis. This covers AQA Practical 12, OCR A 3.2 PAG and 3.1 PAG.
Edexcel A and B Core Practicals 10 and 15 can be completed here.
