Language for learning

Through the activities in this unit pupils will be able to understand, use and spell correctly:

  • names of organs of the chest linked to breathing, eg lung, trachea, bronchus, ribcage
  • names of cells and tissue substances linked to circulation, eg red blood cell, haemoglobin, artery, vein
  • more specialised scientific vocabulary, eg carbon dioxide, oxygen, diffusion
  • words with similar but distinct meanings, eg breathing, ventilation, inspire, respire, inhale, exhale
