Edit : most of you have asked about the which format to put it in. eg. word document , powerpoint , word document , powerpoint....and many others
Well...the letter never stated anything about the format...so i THINK you can put it in anyway you like...
The most important thing is that you have the information all on a hard copy , be it paper or...paper
Enjoy
FrizoN [anyone seen my science file,by the way?]
Sorry to disappoint all you guys but here's the science homework for our holiday
Only reason why only Clement , me , and Glenda received it was because we had some basketball thingy in school, which explains why you all didn't get it.
TLLM Secondary 2 Science

(iv) the importance of the conservation of electrical energy.
- Han in to your science reps/ monitors.
- Science reps/monitors please collect and take note of those who have handed in on the class list.
And that is the science homework for the month.Do finish everything up ASAP...its gonna be one hell of a task. So here's wishing everyone happy holidays and a...a new semester(which i definitely don't look forward to)
