This inquiry leads students through an investigation of human-environment interactions using the ahupua’a of Waimanalo and Kailua as a case study. By investigating the compelling question, students examine the environmental particulars of their region, the ways in which humans have historically interacted with the environment, and the current environmental characteristics. This inquiry embeds the Taking Informed Action sequence, wherein students understand and assess the impact of the human-environmental relationship and act on their proposals to address the negative impacts of human settlement.
