A powerpoint for the N-cycle including a worksheet and clues.
The worksheet is a diagram of the N-cycle with the names of the processes on it, but descriptions left blank, the descriptions are muddled up on the clues sheet. I cut up the clues and hid them around the classroom for pupils to find and fill in the gaps.
