The Junior Landcare Learning Centre is a treasure trove of educational resources covering biodiversity, food production, Indigenous perspectives and waste management.
Each of the 30 minutes lessons provides background information, step- by step instructions for the hands on activities and useful links for ongoing learning. Landcare is a fellow NFP, and all the resources are completely free and curriculum linked. There's probably a Landcare group near you - so there are opportunities to take your learning to the next level through volunteer work.
