Why doesn't the snow melt?

In this lesson, Why doesn't the snow melt?, students experience the phenomenon of a snow pile that takes four months to melt (in 80- and 90-degree F weather) through the lens of energy and matter (crosscutting concept) and engage in science and engineering practices to try to explain why water remains a solid even when temperatures soar well-above freezing.

Why does ice melt without getting hotter?

In the Why does ice melt without getting hotter? lesson, students observe temperature data collected from a beaker of ice water on a hot plate; energy is transferred to the ice water at a constant rate without a change in water temperature (at least for a few minutes). Students actively try to make sense of this phenomenon by engaging in multiple elements of developing and using models and using the thinking tools of patterns and the flow of energy and matter. The goal is for students to begin to make sense of science ideas about water's ability to absorb, store, and release large amounts of energy.
