This lesson plan is for a 7th grade science class covering acids and bases over the course of a week. The objectives are for students to describe properties of acids and bases, differentiate acids from bases, perform experiments to identify acidity and basicity, and appreciate properties of bases. Content will include defining acids and bases, discussing acidic and basic mixtures, and the pH scale. Learning activities include experiments identifying acids and bases using indicators and discussing applications like importance to the body. Formative assessments and a weekly quiz are planned to evaluate learning.
