In this project, students will investigate how temperature, wind, and surface area affect the rate of water evaporation. By observing and measuring water levels over time, they learn about the water cycle and environmental factors that influence evaporation.
If the temperature is higher, then the water will evaporate faster compared to cooler temperatures.

Fill each cup with the same amount of water and mark the initial water level.
Place one cup in a sunny spot, another in the shade, one with a fan, and one at room temperature.
Measure and record the initial water temperatures.
Leave the cups undisturbed for 24 hours.
Measure and record the water levels at the same time each day.
Note the change in water levels in relation to each environment's condition.
Repeat for a week to observe trends.
Graph the change in water level against each condition to analyze results.
Water placed in warmer areas or under a fan should evaporate faster than those in cooler conditions. This demonstrates how environmental factors affect evaporation rates.
Environmental condition (temperature, airflow)
Rate of water evaporation
Amount of water, Type of container, Initial temperature
Ensure cups are secure to prevent spills. Handle all equipment with care, especially thermometers.
Create a chart or graph to display evaporation rates visually.
Include photos of the setup and experiments over time.
Discuss real-life implications of evaporation on climate and water resources.
