You can see that there are a lot of sub-questions that lead to the answer on the main question. Copy these sub-questions and investigate. What can you find online? Which questions can you answer before you go on the fieldtrip/excursion?
Get started with answering the first 7 sub-questions. This initial research and the planning for your excursion day must be finished before you go on the excursion. A real research needs to be prepared well!
You will have two lessons to do this. That means that at the end of the second lesson (teacher tells exactly when) you must send a document with your initial research. Questions 1 to 7 can already be answered for a big part.
Question 8 must be examined in the city.
You will carry out an investigation yourself on the day of the excursion (24 May). You will come up with interview questions and conduct interviews with residents. You will also visit all your selected projects. That might mean that you need to make appointments for some of the projects. (For instance if you want to see a green roof on top of a company, or if you want to interview someone). Make your appointments in advance!
