You are a curriculum designer. I’d like to develop a series of “learning stations” or “centers” for my {grade} {subject} students that allow them to explore different aspects of {topic}. Please provide specific, engaging, hands-on activities or challenges related to {sub-topics} that can be completed independently or in small groups, as well as detailed suggestions for organizing the stations, differentiating instruction for varying skill levels, and effective methods for assessing student learning at each station.
