E4-7 have been outside estimating and measuring the age of trees in the playground. To start with, we estimated the circumference of the tree, using cm as our units, then divided by 3 for a coniferous tree (with needles) or 2 if a broadleaf tree. Next we worked out what year the tree was planted. We used measuring tapes to find the accurate circumference of the tree and then worked out a more accurate age. We compared our two answers. It was fun!
Some science fun in the EM1-3 class this week.
The children were working in groups to identify and classify different tree and plant species in the school grounds.
