DISCUSS THE IMPLICATIONS OF YOUR DATA – WHAT DO THEY MEAN?

Here are some questions you can use to spark your discussion:

Q: Can you determine where plastics are most abundant on your beach using this transect sampling method? In the wrackline, the middle of the beach or the backshore?

Q: What do your results tell you about how plastic is transported in a coastal zone?

Q: What was the most common type of macroplastic on your beach? What about the most common type of microplastic? Which was more abundant – micro- or macro-plastic?

Q: Can you extrapolate your data to determine the average abundance of plastic on the beach?

Q: What are some problems with extrapolating your data this way?

Q: What would you suggest to your city as a way to reduce the amount of debris on the beach?
