The experiment aimed to see if wind affects the rate of evaporation. Two cups were filled with the same amount of water, with one placed under a fan and the other without a fan. Over several days, the water level decreased in both cups, but evaporated faster in the cup under the fan, supporting the hypothesis that wind increases evaporation.

1. Science Experiment

2. Wind makes water evaporate
faster.
Aim of experiment:
The aim of the experiment is to see if wind affects the rate of evaporation.
Hypothesis:
I think the water inside the cup that is under the fan will evaporate faster.

3. Equipment needed
Equipment needed:
0 A fan
0 Water
0 2 Cup(s)
0 Measuring cylinder
Variable Changed:
One cup under the fan, the
other have no fan.
The place, temperature, Etc.
does not change

4. Step 1: fill each cup with the same amount of
water using a measuring cylinder

5. Step 2: Put the cups beside each other
except one with a fan on top of it.

6. Step 3: Put it there for 2 or
more days.

7. Conclusion
The water level had decreased in both
cups but the one with fan evaporates
faster.
