In this lesson students discover some of the incredible uses for plastic i.e. medical science and space exploration and reflect on why single-use plastics have become unpopular. Students examine data from a sample of litter collected on Henderson Island. They go on to consider where the plastic litter could have come from and create a bar graph representing this data.
