Open and Closed Circulatory systems

This is an A level lesson. Students learn about open and closed circulatory systems and then practice comparing the circulatory systems of mammals to fish and also amphibians. The focus is on presenting students with diagrams and teaching them how to analyse the different systems and explain why each is effective for that particular organism. Students complete a worksheet to show their understanding and self assess via a mark scheme (included in the presentation). Finally students compare the effectiveness of a frog’s circulatory system to a mammal. Again students self asses their answers against a mark scheme (provided)
