Pesticides and the food chain
Last updated: 15/11/2023
Contributor: Jane R
This short activity is designed to demonstrate to students how toxins can accumulate in the food chain, affecting organisms far removed from the original source of the pesticide.
Each pair of students needs twenty small slips of paper to represent a dose of toxin. The PowerPoint leads the class through the bioaccumulation activity.
The activity ends with students considering the implications for human food chains.
When the activity has been completed, students can design and produce a large flow diagram demonstrating how toxins can build up in a food chain.
