Have students formulate a question , that they can test later, about water becoming supersaturated. During the next lab activity we will check DO levels of water and determine how to make a supersaturated solution. Students conduct an experiment to explore the possible ways of making an unsaturated, saturated and supersaturated oxygen solution. Using DO kits, students are to determine DO of water under various conditions. The group is to design an investigation and conduct it using the laboratory equipment available.
Students are to make sense of their exploration.
They are to find patterns and relationships and answers to questions. Students are urged to explain their findings and to demonstrate their understanding. Students are to prepare an outline of their findings. Evaluation Call upon students to demonstrate their knowledge and understanding of the ideas under study. As a group, answer these questions.
