Transcript of Science Fair Project

By Jaden Evaporating Liquids Scientists are always studying evaporation to help them understand the water cycle and global warming or climate change better. The purpose of this project is to see how long it takes the liquids to evaporate. This topic is important to study because it helps us learn the rate of evaporation in a certain area. For example, What happens when rivers and lakes dry up in warmer areas.h;if you leave you drink outside for two days and when you come back for it all the liquid is gone. Some things that could affect my project are cloudy weather, temperature, humidity, and many other things. Problem Statement Does the temperature at which a liquid is stored affect the time it takes to evaporate? Hypothesis The water will evaporate faster than the orange juice and the other liquids because the other liquids are made up of many different materials that could make the evaporation rate slower. Bible Verse “As water evaporates from the sea, and a river becomes parched and dried up,” Job 14:11. I chose this verse because our relationship with God can be parched and dried. That means that sometimes in our lives our relationship with God can be separated because of our choices. In my experiment, I am dealing with evaporation and how much has been evaporated from the cup. Materials The Materials that are used are:

water
orange Juice
alcohol
nail Polish Remover
four beakers with measures
pen and paper for notes. Introduction procedures Data 1)Pour the same amount of liquid into each beaker. Note the amounts.
2)Set the beakers in a dry location at room temperature.
3)Monitor the levels of the liquids for 1 week and note any differences. In conclusion, it was determined that the warmer the temperature the faster the evaporation rate. In the end of the experiment, all of the liquids turned out to be almost the same measurement. My hypothesis was wrong because I thought that the water will evaporate faster than the orange juice and the other liquids because the other liquids are made up of many different materials that could make the evaporation rate slower., but the water had the third lowest measurement out of the four liquids. To restate my hypothesis i would say, the temperature of the air and time will affect the evaporation rate of the liquids. If i were to do this project again, i would use beakers to measure the liquids. Pictures Conclusion Over the course of a 7 day period, 4 liquids were used to measure the evaporation. On day one, the liquids evaporated a lot. On the first day, the water had only evaporated only about 10 ml. We were very surprised that it had only evaporated 10ml, Because that is nothing compared to the other liquids. The orange juice had not evaporated at all. I was not surprised because the orange juice contains the most contents in the liquid. The nail polish remover had evaporated the most on the first day. The alcohol had evaporated the same amount as the water, it had evaporated 10ml. I thought that the alcohol would be more like the nail polish remover, but they’re not the same.

These are the results for day 2: The water had only 5ml, it is now at 95ml. The orange juice had evaporated 10 ml, which puts it at 100 ml. The orange juice is on a very slow path to evaporation compared to the nail polish remover. The nail polish remover had evaporated a great amount. It had evaporated 15ml, that puts the NPR at 75ml. Last for day two is the alcohol. The alcohol had only evaporated 5ml. The alcohol is currently at 95 ml. That is a wrap on day two.

On day three the liquids were a whole mix of results. The water has finally started to evaporate more. The water had evaporated 10 ml, and it seems that the water has started to hit its breaking point. The orange juice has remained the same measurement for two days. The NPR has also remained the same as on day two. and last but not least the alcohol, that had a measurement of 80 ml.

For a total of three days these were the results. The water had evaporated about 10 ml. In the glass, the water is at about 50 ml. The orange juice has evaporated about 35 ml in 3 days. the orange juice has hit a point where it has started to evaporate more than usual. The NPR has evaporated about 20 ml in these three days. I was surprised that it hadn’t evaporated more than the orange juice because the NPR has had the fastest evaporation rate so far. In these three days the alcohol had evaporated 30ml. The last paragraph is going to be the final results of this project.

The Final measurement of the water is 50 ml. That is a grand total of 60 ml that has evaporated in 7 days. The last measurement of the orange juice is 50 ml, that is the same as the water. The last measurement for the nail polish remover was 40 ml. Which has a total of 70 ml that has evaporated in seven days. Last but not least is the alcohol. the alcohol had a final measurement of 40 ml. The alcohol had evaporated a total of 70 ml like the NPR. Results Graph
