TEKS Objective

The student is expected to explore the processes in the water cycle, including evaporation, condensation, and precipitation, as connected to weather conditions.

Essential Understanding

The student knows that there are recognizable patterns in the natural world and among objects in the sky.

Science Background

The Water Cycle, Evaporation: US Geological Survey (website) - Learn what evaporation is, why it occurs, and the role it plays in the water cycle.

Assessment Ideas

Have students create drawings of examples of evaporation in their science notebooks, and use a few sentences to describe their drawings. Examples might include a puddle drying up, water vapor from a heated kettle, etc.
