Unit Summary

This first Ecosystems & Evolution unit consists of six exciting lessons that immerse students in the world of living organisms and their relationship in an ecosystem. Initially, the students will explore competition between species and learn about the concept of natural selection - and how it drives evolution - before exploring interdependent species. They will then discover the delicate balance of interdependence among various organisms within ecosystems, including the complex world of food chains and food webs. They will then investigate real-world examples of environmental disasters and their consequences for living organisms, describe factors that affect human food security and delve into the relationship between human populations and ecosystems. Finally, in Lesson 6, the students will explore the importance of maintaining biodiversity. They will discover the significance of biodiversity in supporting ecological balance and how it contributes to the resilience of ecosystems. 

By the end of the unit, the students will have developed a solid understanding of ecosystems and the intricate relationships among species. They will have honed essential skills such as critical thinking, data analysis, communication and problem-solving and will have explored all the knowledge and skills required before progressing to Ecosystems & Evolution 2.
