On Monday, the Year 4s went out into the local area to conduct an investigation into levels of air pollution. We placed cards smeared with Vaseline outside school, in a park, near a factory and close to the main road. We predicted that the cards that are nearer to traffic or plant machinery will be dirtier due to more air pollution being produced. We always used data loggers to measure the sound in decibels in these areas. The children predicted the noise levels in each area too. We will analyse the results next week and write up what we found out.
