Figure 2. Snap-top vials with sediment and microplastic samples (left) for the model experiment of sediment analysis. The reserve containers with microplastic contents are located on the right. 40 g of sediment are contaminated here with a known number of microplastic particles. The type of plastic and the number remains initially unknown to the students. Subsequently, this sample is analysed by means of the sediment separation procedure, sand is separated from plastic and then re-assigned to the samples or everyday objects
