Separate a change of state from movement to another place
Trace several water-cycle pathways, explain the roles of solar energy and gravity, and use a selected DC middle-school NGSS reference.
The DC science standards directory identifies NGSS adoption in December 2013 and links the standards publisher. Use the Publisher NGSS document for the selected performance expectations and their examples and boundaries. NGSS middle-school expectations use a Grades 6–8 band. The activity here is a suggested study focus; consult the school’s plan for its local grade placement.
Follow a water pathway without forcing it into one loop
An original conceptual model begins with liquid water at the surface. It allows evaporation, condensation, precipitation, infiltration, and downhill flow. Use the table to distinguish a change of state from a change of location. Then show two possible paths after rain reaches the ground.
Explain the evidence or model
Evaporation changes liquid water to water vapor. Energy from the sun helps drive evaporation at Earth’s surface. Condensation forms liquid droplets when water vapor cools under suitable conditions. Falling rain moves liquid water from clouds toward the ground under gravity. After reaching the ground, water can flow over the surface or enter the soil and move underground. These branches mean that water does not have to follow one fixed sequence through every named process.
| Step | State change? | Location change? |
|---|---|---|
| Evaporation | Liquid to vapor | Water enters the air |
| Condensation | Vapor to liquid | Droplets form in the air |
| Falling rain | Not required: liquid stays liquid | Cloud toward ground |
What to check in the explanation
A cloud’s visible droplets are not the same as invisible water vapor. Drawing condensation as vapor falling to the ground mixes up a phase change with movement. Rainfall itself is not necessarily a phase change: liquid drops can remain liquid while moving downward. Sunlight supplies energy; it does not supply new water molecules to the cycle. Gravity helps move water downward, but it is not the explanation for vapor turning into liquid droplets.
Plan the next activity
- Label where water is found and whether it is liquid, solid, or vapor at each chosen step.
- Use different arrow labels for phase changes and location changes.
- Add more than one path after precipitation and explain where energy or gravity contributes.
Add water taken up by a plant and returned as vapor through transpiration, or add water stored as snow and later melted. Explain that storage can delay a pathway rather than remove water from Earth’s cycle. Identify what the model leaves out, such as travel times or local amounts. This activity belongs to the NGSS middle-school band; its Grade 6 placement is a suggested study focus, not a separate DC assignment of the complete band to this year. Consult the school’s science sequence.

How does Grade 6 connect to DC’s science assessment?
Grade 6 is outside DC’s NGSS summative assessment grades. DC CAPE Next begins in spring 2027 and lists science assessments in Grades 5, 8, and high-school biology. OSSE says the educational standards have not changed. Resources here are independently published practice, not official state assessments or predictions of a state score. Read the official guidance.
Must every water molecule follow the same cycle diagram?
No. Water can follow different pathways and remain in a reservoir for different lengths of time. A useful model includes branches rather than one compulsory loop.
Where should I check the complete science requirements?
Start with the DC science standards directory and the official NGSS references. Middle-school MS expectations apply across Grades 6–8; confirm the local sequence with the school. The selected investigation and resources here do not certify complete course coverage. Read the official guidance.
