Water: Resources and Conservation
This chapter explores **water** as a resource — its uses, **conservation**, and the **water cycle**. Students learn about **evaporation, condensation, and precipitation**, as well as the importance of saving water for the future.
Key Topics & Instructions
▼- Identify the three states of water and phase changes (melting, freezing, etc.).
- Understand the main processes of the water cycle (Evaporation, Condensation, Precipitation).
- Recognize the importance of water conservation.
- Use Experiment 1 to explore phase changes in water based on temperature.
- Use Experiment 2 to simulate a process of the water cycle.
Experiment 1: Water Phase Change
Input a temperature to see the state of water and the required process for change.
Experiment 2: Water Cycle Process Simulator
Select a water cycle process to see the resulting state change.
Only a small fraction of the Earth's water is available as fresh water. Conservation is crucial to manage this finite resource for drinking, agriculture, and industry.
The Water Cycle
The process where **liquid water** changes into **water vapor (gas)** due to heating (e.g., sun heating oceans).
The process where **water vapor (gas)** changes back into tiny **liquid droplets** upon cooling (e.g., forming clouds).
The process where the condensed liquid droplets fall back to Earth as **rain, snow, or hail**.
