Lesson summary

This lesson incorporates clips from Blue The Film as learning inspiration. Students examine and compare the respiratory systems of humans, sharks and marine turtles. They begin by working as a class to brainstorm what they already know about respiratory systems, and then investigate how human respiratory systems work. They then work in groups to investigate and compare the respiratory systems of a shark and a marine turtle and create an infographic or poster to share the results of their research. Finally students are asked to think about why having an understanding of body systems – such as respiratory systems – helps scientists to care for and protect animals.

Learning intentions:

Students can...

  • understand how studying the physiology of animals can help us protect them.

Success criteria:

Students will...

  • know what the respiratory system is, what the features of respiratory systems are and how respiratory systems differ between some animals
  • know why we need to understand animals in order to protect them
  • be able to conduct research online and from videos
  • be able to annotate a scientific diagram.

Additional info

Blue is a feature documentary film charting the drastic decline in the health of our oceans. With more than half of all marine life lost and the expansion of the industrialization of the seas, the film sets out the challenges we are facing and the opportunities for positive change. Blue changes the way we think about our liquid world and inspires the audience to action. Find out how to screen or download the film here. Along with the film is an ambitious global campaign to create advocacy and behaviour change through the #oceanguardian movement.
