Dancing Density Open Response

This passage discusses how water’s density changes with temperature, particularly how it behaves differently compared to most substances. Water reaches its maximum density at 4 degrees Celsius, but when it cools below that point, it becomes less dense and expands. This property allows ice to float and affects bodies of water by creating a unique layering effect. The passage also explains how water behaves when it heats up, becoming less dense as it warms.

Reading this passage improves vocabulary with terms like “density” and “anomaly.” It strengthens comprehension skills by guiding students through water’s unusual behavior in response to temperature changes. Critical thinking is fostered as students must reason why water behaves differently compared to other substances when it cools and heats. Additionally, the clear explanation of these complex concepts helps students build sentence structure proficiency in scientific writing.
