One day at home, I was looking at a book and I saw that it showed the evaporation of water. That’s how I got my idea for the experiment. When I told my teacher, she approved it. The idea is to fill two jars with water with no lids and place them in different climates. Which one evaporates faster? The materials are:

1. Two jars (no lids)

2. One marker

3. water

4. measuring cup if you need it

Also here are the steps: (Method or procedure)

Mark the glasses in inches.

1.Pour water  into jars or use a measuring cup.

2. Place jars in different climates.

3. Every day see which one evaporates faster.

You have to be accurate when you pour the water, so use a measuring cup. Before you start this experiment, you should make a graph and write the 7 days in a week. You have to do that because so you can keep track on how much water evaporated. The right time to write the record the data is 12:00. You have to make sure you write the data everyday. As you can see in the picture, you also have to label the jar in inches and pour it up to 3 inches. The problems I had was accuracy, it’s hard to keep track of how much water evaporated. If you write the data, it might not be accurate.

I observed that in 5 days, water evaporated 1 inch from the outside jar. During the same time, water evaporated from the indoor jar, only about half an inch. After a while, I realized why one of the jars is not evaporating quickly. I put one on the terrace and one near a sunny window. If it’s near a closed window the Sun can’t get to it much, so the Sun can’t evaporate the water. Also, when I put the other jar on the terrace, it evaporated quickly. So that is the evaporation of water project.
