1. How does water cycle into and through the atmosphere?

evaporation
transpiration
condensation
crystallization
precipitation
water cycle
aquifer

MS-ESS2-4

Interpreting diagrams and models of water in the atmosphere
Explaining cause-and-effect relationships in evaporation, condensation, and precipitation
Using evidence to support explanations of how water moves through the atmosphere
Applying academic science vocabulary in context
Analyzing text and visuals to predict changes in weather or climate

Students explore how water exists in the atmosphere and how processes like evaporation, condensation, and precipitation move water through the air.
To help students understand the role of atmospheric water in the water cycle and its effect on weather and climate.
DOK 2 (Skills & Concepts)

Observing clouds, rain, and humidity in local neighborhoods
Connecting weather patterns to daily life (commuting, school activities, outdoor sports)
Discussing local water sources and their impact on communities
Relating precipitation and evaporation to urban gardening or parks
Connecting atmospheric water to personal experiences with storms or rainfall

Clouds are made only of water, not tiny droplets or ice
Rain falls immediately after clouds form
Water only moves vertically (up and down) in the atmosphere
Evaporation removes water completely, leaving none behind
Water in the atmosphere is disconnected from the rest of the water cycle

Use diagrams, videos, and physical models of the water cycle
Provide sentence stems for explaining atmospheric water processes
Pair or group students for observation and discussion activities
Highlight and chunk key vocabulary (evaporation, condensation, precipitation, humidity)
Connect content to local weather patterns or experiences
Use graphic organizers to trace water movement in the atmosphere
