A detailed lesson plan outlining how learners are introduced to the topic of animal tracking, and how their knowledge and vocabulary are carefully expanded. Students are shown 'evidence' of an animal having been present, and must speculate about what type of animal left it, and what other types of evidence animals might leave. They then create a device for collecting evidence of an animal and place it in the schoolyard, where it is monitored. Suggestions for follow-up activities are provided as well.
