Field Trip - Sungei Buloh
Guide to the Mangroves of Singapore http://mangrove.nus.edu.sg/guidebooks/text/1025.htm

You will complete all criteria for this assessment - Pl, DCP and DEC. It is therefore essential that your Plan enables you to mathematically process and present the data obtain and to then discuss and evaluate in a context, based on research. Though you may brainstorm ideas as a group, each student must plan an individual investigation. Please read the Risk Management Assessment for this field trip, as this will provide an indication as to what kind of investigations cannot be performed. You will need to check availability of any equipment you may need, with your teacher, in your planning phase. With the assistance of your teacher, you will then need to gather the equipment you need at least one day in advance of the field trip. Please refer to the permission letter to ensure that you take/wear the correct items for this field trip (sunscreen, sun hat, lunch, drinking water, etc).
