Materials:

• A glass of water
• A marker or tape
• A sunny or warm place

Step 1: Prepare

Fill the glass halfway with water. Use the marker or tape to mark the water level on the glass. This way, you can see if the water goes down.

Step 2: Place the Glass

Put the glass in a place where it gets sunlight or is warm, like near a window. The heat helps the water evaporate faster.

Step 3: Observe

Each day, check the glass and see if the water level has gone down. That's because the water is evaporating, which means it's turning into gas and going into the air.

Step 4: Conclusion

After a few days, you'll see that the water keeps going down. That's evaporation! When water heats up, it changes from liquid to gas, rising into the air.

It's like what happens to puddles after it rains: when the sun comes out, the water disappears. It's the same idea!
