Science KS2: Respiration - how is oxygen transported round the body?

Zoe explains how oxygen is transported around the body in our blood.

Graphics show how when we exercise, our lungs work harder to take in oxygen and our heart has to work harder to pump it around the body.

Zoe and the children do a lung capacity experiment, and discuss the dangers of smoking.

CGI animation explains the makeup of the air that we breath and how nasal hairs and snot filter out impurities such as airborne dust and pollen.

This short film is from the BBC series, Amazing Me.

Teacher Notes

You could create a lung capacity experiment using the filmed demonstration as a template.

Measure the different lung capacity of the children in your class and create a graph to represent this and work out the average lung capacity of your pupils.

A graph could be created based upon the number of children in the classroom that have allergies to pollen or other airborne causes.

Collect data about the locality of the school regarding pollution and other factors, and discuss how pollution affects our breathing and health.

Talk to the local environmental officer about this; you could invite them to visit your school to make a presentation.

Curriculum Notes

This short film will be relevant for teaching the topic of the human body at KS2 in England, Wales and Northern Ireland and Second Level in Scotland.
