Students design a survey of school waste bins (rubbish, recycling and composting) that estimates volumes of waste before and after lunch and estimate the percentage of contamination. They calculate the area the bins service by breaking up the area into squares and triangles.
Students investigate how recyclable material is sorted by applying some of their known properties. They focus on the science behind sorting at a MRF – Materials Recovery Facility. Students explain the entire loop for an aluminium can.
Students complete a biodiversity survey of their school’s compost bins. They then collect data to determine how successful their school’s green waste is operating. Students make recommendations to their school community on improvements to the school’s composting system.
