Hi Sec 1A! A big warm welcome to the school! Being new, you girls must be feeling rather excited and may be a little lost too. Mixed feelings, I bet.
Don't worry, relax and we'll get through this together! Some announcements:
1) Get a ring file (preferably blue colour, any shade of it) to file your Science worksheets. You may make or buy your own dividers to categorise the notes and worksheets into : a) notes, b) worksheets, c) reflections and d) miscellaneous. 
2) Get an exercise book (may be B5 in size, if you prefer an A4 one, go ahead). This will act as a journal cum notebook for Science. Decorate the book but there's a theme to stick to. The theme is "Science". 
3) other classroom routines and rules will be set in class.
That's all folks! Looking forward to seeing you girls in class!
