A 22 page colour teacher guide to extend student understanding of food chains and the interconnectedness of the natural world. Based around two ideas: the fi rst explores food chains and webs with soil as a focus. The second idea builds on the first by providing insights into how soil is a non-renewable resource and degradation of soil leads to instability in food chains. These teaching ideas can augment relevant existing lessons in a work program. The teacher guide includes questions, activities and links to online resources.
