Knox Grammar School
Toby Bishop, Sarah Sherlock and Roseanna Huang confidently taught their audience about the impact of feral animals in the environment.
Established in 1998, Kids Teaching Kids (KTK) is a nationwide program which engages young people to be future environmental leaders through enquiry-based learning.
Students are empowered to determine and investigate issues in the environment and then present their research to an audience of other school children.
Wahroonga Prep has been a strong supporter of KTK for many years.
Toby, Sarah and Roseanna demonstrated how cat and rabbit populations, if uncontrolled, can destroy native wildlife, vegetation and habitats with devastating results.
