Entry Events

Events that will be used to introduce the project to students

The Invasive Species Challenge

Students are introduced to a fictional scenario where an invasive species threatens the local ecosystem. Using real data and simulations, they must devise strategies to manage and control the invasive species, fostering critical thinking about ecosystem balance.

Urban Wildlife Quest

A wildlife expert visits the class with tales of how animals adapt to urban environments. Students embark on a quest to discover local species and analyze how urbanization affects biodiversity, fueling inquiries about human impact on ecosystems.

Microhabitat Marvels

Students explore the microhabitats in their schoolyard, collecting samples and observing the interactions within these ecosystems. This hands-on approach engages them in analyzing biotic and abiotic factors that influence population dynamics.
