Δράση
step 1
Students will place test kits in 3 different areas: inside the classroom, in the playground and in a local park.
step 2
Students will then test each area at the beginning of the week, middle of the week and end of the week, to observe if levels of pollution changes and collect data.
step 3
While in the local park, students will also go on a lichen hunt. Lichens are regarded as pollution indicators because they are sensitive to sulphur dioxide (SO2) and do not grow in polluted areas. Their presence indicates the absence of pollution in an area, and their absence indicates that the area is polluted.
step 4
The students will create a table to show and compare the pollution levels in the 3 areas. They will analyse the data and write explanations about why they think the pollution levels varied on different days.
