Sorry to say but it was such a headache for me as well everytime when I knew they need to start to do the science project.
During Christmas holiday, they need to do Christmas homeworkssss, prepare assement (I knew was not suppose to push them only during Christmas time, but still need to do some revision with them), pratice instructment-30min to 1H everyday plus need to do the science project (Searching from the libary, computer, book store etc and sometimes need to do the 3D artwork). I hate to do this with them and I really have 0 knowledges on those topics.
My opinion think the science project should only start with the P3 student and up. P1 and P2 are really too young to understand all those issue-they might, but i think parent should spent lot lot lot of time to explain before they can understand some of it-sorry I am only talking about my kids.
