Saved science fair projects:
This is a saved copy of the relevant third party website. We save only the first page of every project because we've found that the third party sites are often temporarily down. We do not save all pages of the project because copyright belongs to the third party author.- This experiment will show you how factors such
as temperature, wind, and surface area affect the rate of evaporation.
pan balance
sponges of different sizes
scissors
plastic sandwich bag
spotlight
hot water
cold water
electric fan
jar lid
WHAT TO DO:
1. Using the materials listed above, design an experiment to see how wind, temperature, and surface area affect the rate of evaporation. Make a prediction about the effect each factor will have on the evaporation rate.
2. Next, conduct the experiment using the materials provided to test your predictions. Record all your steps for carrying out the experiment.
NOTE: Every factor should be the same except the factor that you are testing. For example if you are testing the affect of wind on evaporation rates, the sponges should be the same size, and they should be exposed to the same temperatures. The only thing that should be different is the exposure to wind.
WHAT NOW:
Create a chart showing the results of your experiment. Make sure you include the results for all three factors (wind, temperature, and surface area).
