Data Collection

Time: 60 minutes

[On Fieldtrip] Trawling and Surveying for Plastic Pollution

After travelling to the shoreline, students should split into their respective groups, and follow the protocols to collect data on local macro- and microplastic pollution.

Evaluate

Time: 10 minutes

[In Classroom] Sharing Experiences

Invite students to reflect on what they say either back in the classroom or while travelling. Were they surprised at any of the findings? Did they have any difficulties with the tools? What might they do differently next time?
