## Introduction

In this experiment, we will recycle urine with the help of natural processes like evaporation, transpiration, and condensation. The project aimed at the people who planned future trips to Mars and also the astronauts. With this method, we will try to help reduce the cost of taking water on the space station.

## Aim

To recycle urine with the help of evaporation, condensation, and evaporation.

## Theory

We hypothesized that the natural process of evaporation, condensation, and transpiration would score the highest.

## Requirements

1. Funnel urine

3. Rubber stopper

4. Condensing tube

5. Hot plate

6. Green bean plants

7. Plastic cups

## Procedure

Step 1: Into a glass flask, collect funnel urine (2 gallons) for a period of three weeks.

Step 2: After the collection, place a rubber stopper into it.

Step 3: Take a condensing tube and connect the flask with it.

Step 4: Take another flask and connect this with the condensing tube with an arm that is extended from it.

Step 5: Into this, another flask attaches another rubber tube.

Step 6: Place this flask on a hot plate.

Step 7: Leave the flask for 10 minutes to boiling.

Step 8: After 10 minutes, you will see H2O collected in the flask.

Step 9: Take a test tube and keep the obtained H2O in it in a safe place.

Step 10: Repeat this process of boiling

Step 11: For the transpiration process, give ¼ cup of urine to green bean plants.

Step 12: Take the second set of plants and give ¼ cups of condensed and evaporated to them for transpiring H2O.

Step 13: Take clear plastic cups and place the obtained water in their respective cups. This compares the odor and clarity of the obtained samples.

## Observations

1. For this experiment, we prepared a scale that lay from 1 to 10. 1 is for the dirties sample as compared to the drinking water. And 10 is the cleanest water as compared to drinking water.

2. The process of evaporation and condensation acquired number 7, which was fairly clean as compared to the transpiration, which scored 4.

3. The natural process of condensation and evaporation was the easiest and most efficient.

4. The process of transpiration was also successful but produced less than 1 milliliter of water.

5. Because of the less production of evaporated and condensed water, we could feed the plants, and the process of evaporation, condensation, and transpiration did not work.

## Result

1. The hypothesis that we assumed that the evaporation, condensation, and transpiration would score highest was wrong.

2. This came to number 1.

3. We produced no H2O because we fed less evaporated (only 5 ml) and condensed H20 to it.

4. Instead of feeding 5 ml of H20, if it had fed 750 ml of H20, the result probably would have been different.

5. The problem that I think lies in the amount of H20 that I collected from the evaporation and condensation of urine.

6. The reason why plants could not transpire H20 is the time constraints.

7. If I had more time, evaporation and condensation produced more H20. And this could have given more sustenance to the plant to transpire.

## Precaution

1. Make sure the flask and tube are clean.

## Conclusion

In this experiment, we aimed to find out the best way to recycle urine into water.

Q.1 What was the aim of your experiment?

ANS. We aimed to recycle urine into the water through evaporation, condensation, and transpiration.

Q.2 Did you create water from urine with the help of evaporation, condensation, and transpiration?

ANS. No, we could not create H20 from evaporation, condensation, and transpiration because of time constraints.
