The Year 4 super scientists undertook some fieldwork this week. They will be comparing the level of air pollution in 4 areas within our locality and so they suggested some areas to test and off we went to place our test cards. One side of each card was covered with a thin layer of Vaseline with the idea that some particles released from vehicles and machinery will stick to the cards and we can observe and discuss the level of pollution in each area. We also took a reading of the noise level in each area using a decibel meter so that we could determine whether there is a link between noise level and pollution level.
