NGSS Shift: Learning vs. Figuring Out

Learning about a science idea

Knowing about convection, the water cycle, phase changes, and clouds.

Figuring out how and why it works

Developing a model that explains how clouds form because energy makes matter cycle in the atmosphere Being able to describe why clouds are made of water

Being able to explain how clouds form in the air

Being able to trace the matter and energy within the atmosphere system
