Which question would promote divergent thinking among sixth graders studying lakes?

The selected question effectively promotes divergent thinking because it invites students to explore a complex scenario with multiple potential outcomes and implications. By asking how the lake ecosystem would be affected by drought conditions over a prolonged period, students are encouraged to think critically about a variety of interconnected factors, including the relationships between organisms, water levels, and environmental conditions.

This approach allows for multiple valid responses, as students can explore various angles, such as the impact on fish populations, plant life, water quality, and even human activities. It encourages them to consider broader ecological concepts and to think beyond simple, factual answers. In contrast, the other questions focus more on specific, factual information or straightforward inquiries that do not necessarily foster creativity or expansive thinking in the same way.
