Worksheet (Word) to review the structure and function of a pacinian corpuscle. Analysis of skin receptor density using graphical data. Label the sensory neurone (review GCSE). Graph data based typical skin receptor density values. Draw a deformed pacinian corpuscle and depolarisation. Extension: Describe techniques to collect the receptor density

Cut and stick worksheet to review the formation of tissue fluid and it’s return to the blood. Reviews cell structure and exchange surfaces. Link water potential and hydrostatic pressure to the formation. Construct and label tissue with it’s blood supply. Add annotations on exchange, hydrostatic pressure and water potential. Extension: Add detail of the circulatory system to the diagram. Worksheet could be used to consolidate a lesson on tissue fluid.

Worksheet (PDF) to review the structure of the gills. Analyse counter-current flow using graphical data. Link the mechanism with exchange in the gill over the lamellae. Sample answers provided. Label the gills with increasing detail. Graph data based on oxygen concentration in water and lamellae. Draw a sketch graph on parallel flow. Extension: Link graph to lamellae structure. Worksheet could be used in conjunction with fish head dissection.

Students use the element of the worksheet to construct a model antibody and annotate it in detail using the suggested terms. Great activity to assess understanding. It provides opportunity for differentiation.
