Heart rate, breathing rate and physical fitness

This lesson is designed to exemplify an argumentation approach to practical work using an ‘analysing and interpreting data’ framework.

Students use primary data about heart rates and breathing rates, alongside secondary data from children and adults, to assess and argue for or against the validity of claims about physical fitness. They consider whether the evidence is sufficient in itself to support the claims, particularly when the sample size is small, or whether more data is needed.They justify their decisions through argumentation.
