Teachers notes
Safety issues:
Ensure that the DrDAQ data logger does not come into contact with the water.
Thymol can be halmful if swallowed, inhaled or absorbed through the skin.
Target age groups:
Ages 9 -19 (Key Stage levels 3 - 5)
National curriculum:
Here the process of aerobic respiration can be clearly indicated by the reduction in oxygen level (indicated by the oxygen probe) over time. KS3 Sc2 Life processes and living things. Green plants as organisms. Respiration. 3e that plants carry out aerobic respiration.
