I need to measure evaporation for one (1) week for a project for my child. I am looking for information to do this as accuratley as possible. Would love any help or suggestions. Thanks.

This could be a fun experiment to do. Take two containers that are identical and pour a measured amount of water into each one. You want to measure how much water you put in so that you can compare it later with how much is left to quantify how much water evaporated over the testing time.

Set one of the containers in a warm, sunny location and one in a cool, shaded section. This will help contrast how sunlight aids the evaporation process.

After your time period expires, measure the remaining water in each container and record your results. You can subtract the amounts recorded from the starting amount and list exactly how much water evaporated from each container over the time period.

Another level for this as a longer term project would be to record the relative humidity in the testing area each day and average it out over the testing time period. Then wait a month or two and repeat. This would help identify how outside weather and relative humidity impact evaporation rates.

I found this while I was out roaming the Internet. It's very similar to what I proposed: http://www.teachervision.fen.com/tv/printables/orange/se-61.pdf

You may want to place a thermometer next/close to each container and record the temperature at, or better in, each container.  Record the temps at the same time each day.
