This resource serves as a teacher guide focused on the concept of pH and its application in defining, differentiating, and classifying substances as acids or bases. It outlines the purpose of the assessment, which is to communicate the relationship between the chemical structure and properties, such as pH levels and corresponding color changes of indicators. The guide features an interactive poll for students to gauge their understanding of acids and bases, along with detailed explanations of the pH scale (0-14), examples of common indicators like litmus paper and phenolphthalein, and their reactions in acidic and basic solutions. There's also a section comparing household substances and their approximate pH values, providing educators with interactive questions to facilitate learning. Additionally, it emphasizes the use of universal indicators for a precise understanding of pH levels. The document concludes with engaging questions to review student knowledge and an exit ticket prompting students to identify acidic and basic substances from their homes.
