This science project investigates how the exposed surface area of water affects its evaporation rate. The hypothesis proposed that a larger exposed area leads to a higher evaporation rate. After conducting experiments with different container sizes, results indicated that containers with a larger exposed area indeed evaporated more water than those with smaller areas. The findings confirmed the hypothesis and provided clear data to support it. The project emphasizes the importance of patience during the experimental process, as evaporation takes time to observe.

Science Project Title Chen Jun Jie | 5/2 | Beacon Primary School
To find out how exposed surface area affect evaporation.
Hypothesis • The larger the exposed area, the higher the rate of evaporation.
Variables
Materials
Procedure
Data/Observations The containers that had a larger exposed area evaporated more than the other containers.
Conclusion • The larger the exposed surface area of the water, the higher the rate of evaporation. • The data supports my hypothesis
Reflection • The process takes a lot of patience as it takes time for the water to evaporate.
