Water cycle

Step 1 - Activities

Let’s obtain distilled water

Let’s look for answers to the following questions;

Why is there a cloud in the air when it’s raining?
Which phase changes do you think water is going through during the formation of the rain drops?
Which phases of matter can be observed during condensation?



Let’s add 2 glasses of boiling water into the large bow in the figure and add a spoonful of food dye. Let’s place the small bowl in the middle of the large bowl (the water level should not get above the rim of the small bowl.). Let’s cover the large bowl using stretch film and place the coin on the film exactly above the small bowl. Let’s observe the small bowl, which was empty at the beginning of the activity, after two hours.

Has water accumulated in the small bowl?

If it has, what is its color and its taste like?



The color of the water placed in the large bowl is deliberately changed using food dye at the beginning of the activity. An accumulation of liquid has been observed in the small bowl at the end of two hours. The color of the accumulated water is different from that in the large bowl and it is clear as water. The taste is also different from that with food dye added into.
