Internal Assessment Overview:
In geography, traditionally plan, perform, and collect fieldwork together HOWEVER EVERYONE WILL WRITE THEIR OWN REPORT! Worth 20% of your total grade, marked by Ms. S. and then audited externally (selected few chosen and regraded by examiners). Rough Draft Due September 11th, Final Copy due September 25th (one month and half after return to school).

Our Topic; Ocean Plastic
Estimated over 5 trillion plastic pieces in the ocean Estimates range between tonnes Most plastic found in regions of one of the 5 gyres as a result of wind and wave action ‘corralling’ plastic floats in the center of the energy (GPGP) Plastic is sorted into 2 categories - micro and macro plastic – micro being smaller than 5mm in diameter Micro plastic particles the result of fragmentation of larger items OR runoff from cosmetic/synthetic clothing

Micro and Macro Plastics in Gyres
Grand Bahama is uniquely positioned on southwest of the North Atlantic Gyre, right at the start of the Gulf Stream Current (A), where currents (and upwelling from ocean trench) should be ‘pushing’ plastic towards the middle of the North Atlantic Gyre.

To what extent are the beaches of _______ and ________ polluted by ocean plastic?
10
Possible Hypothesis: We will find more plastic debris than any other debris on the beach The beach with regular the clean-up crews will be more heavily polluted than the beach without clean up crews We will find more macro plastic than micro plastic (or vice versa) We will find more plastic on the south side of island than the north We will find more plastic on west end of the island than the east Our beaches will be more or less polluted than other beaches (beaches in San Fransisco or the USA) The beach with more ocean plastic will have lower environmental quality
11
Investigations: Your Appendices (Thank You 5 Gyres!!!)
Your Task: - Look over the transect materials to get an idea of how the transects will occur next week. - Look at your three hypothesis: how will you prove or disprove each one? These are your methods. - Look at your methods; how will you interpret the results after you gather the data? Do you know of any statistical calculations?
