This is the second part of the letter I need to prepare. I really need your help to improve the word choice. Thank you very much in advance.
1) This two-year project will be mainly about a comparative study on biodiversity in water and other waterways in our local areas and English has been chosen as our lingua franca.
2) In particular, your school could help our Italian science teachers build a scientific vocabulary in English to be used when working on the project.
3)This preliminary work will then enable our students to communicate the results of their achievements to the Irish students involved in the Comenius project.
4) We have decided to hold a preliminary meeting in Italy on 27. January and 28. January in order to agree on the objectives and the number of mobilities of both teachers and students which will occur (??) in the course of (during?) the two years.
5) The German school will act as coordinator of the project and so is responsible for drawing up the project itself and sending it to its national agency by 21 February.
6) We, as partners, we'll have to send a copy of the same project to our local agencies by the same deadline.
Here are some suggestions to improve the word choice in the second part of your letter:
1) This two-year project will primarily focus on conducting a comparative study on biodiversity in local water and other waterways. English has been selected as the common language for communication.
2) Specifically, we would greatly appreciate your school's assistance in helping our Italian science teachers develop a scientific vocabulary in English, which will be utilized during the project.
3) This initial work will allow our students to effectively communicate their research findings to the Irish students involved in the Comenius project.
4) In order to establish the project's objectives and determine the number of teacher and student exchanges that will occur over the next two years, we have scheduled a preliminary meeting in Italy on January 27th and 28th.
5) The German school has taken on the role of project coordinator and, as such, is responsible for drafting the project itself and submitting it to the national agency by February 21st.
6) As partners, we are required to submit a copy of the same project to our respective local agencies by the same deadline.
Remember to tailor these suggestions to fit the overall tone and style of your letter.
