Children's Water Festival
Chatham Kent
Deadly Link
Overview
Students become herons, fish, and mayfly larvae in a highly involving physical activity.
They discuss how the food chain works and how toxic substances can enter the food chain, with a variety of results. i.e. Larvae are tiny so it doesn’t take much (pesticide) to kill them.
Students will also discuss alternatives uses of pesticides.
e.g. Organic gardening, biological controls, predatory insects and genetic approaches to minimize crop damage.
Objectives
Students will be able to:
1) Give examples of ways in which pesticides enter the food chain
2) Describe possible consequences of pesticides entering food chains
3) understand bioaccumulation
