Water is essential for all living things, leading many cultures to proclaim, “Water Is Life.” In this unit, students investigate natural water systems to determine whether they are healthy or unhealthy, considering different species' needs and exploring ways to improve water quality. Students begin by analyzing four water samples (Lake, Pool, Metallic, and Rain Water) and creating models to explain what might make them healthy or unhealthy. They observe properties to identify materials in the water and design a filter to remove visible contaminants. However, they realize that some unhealthy particles remain. To further purify the water, students explore heating methods. They test boiling and analyze second-hand data, discovering that boiling works for only one sample. They then investigate solar stills as another separation method, but the process proves slow. Looking at large-scale solutions, students research water treatment methods and experiment with adding substances to remove contaminants. Finally, students apply their knowledge of science and engineering to design solutions for a real-world water issue, with opportunities to address local concerns. Through hands-on investigation, they develop strategies to improve water quality for different purposes. The material is distributed in accordance with the CC BY-NC.

Traditionally, many schools have focused on academic achievement as the primary end of education. As schools increasingly expand their aims to include wellbeing, some have struggled knowing how to translate the growing body of wellbeing research into their daily practice. The purpose of this book is to help educators understand the research behind wellbeing and select appropriate assessments that will begin fostering wellbeing in their context.

Have you ever wanted to read, but it was too dark? Have you ever been reading under covers and been told to turn off the lights? This unit begins with a shared experience of trying to read in the dark under covers made of different materials. Students plan and carry out investigations together to produce evidence that can answer their questions about the phenomenon. Through these investigations, students gather data about how transparent, translucent, opaque, and reflective materials cause light to pass through, be blocked, or change direction. As the unit progresses, students use a new model to explain how they can successfully read under covers that block light. At the end of the unit, students apply these ideas to write an informational text to communicate information about reading under covers to members of their community.
