Water Cycle

 

Water is an important asset to life. The water cycle is important to the ecosystem, and it keeps the balance of life. From the water being absorbed by the sun into the clouds then the clouds rain down water and the water goes from the ground into the ocean and then back up to the clouds, which is called evaporation.

Activities for Water Cycle For Students (but Teachers can aid):

All Activities unless said other wise is from different websites but I don’t know where…sorry.

 

ACTIVITY ONE

Condensation

You'll Need

 

 

What to Do

  1. Fill one of the glasses with the ice water and set it on a table. Wait briefly.
  2. Feel the outside of the glass. How did it get wet? Where did the water come from? Is it necessary for the glass to be filled with water for moisture to form on the outside?
  3. Set one of the empty glasses on a table as a control. Place a second empty glass in the refrigerator, and the third in the freezer.

4.      After about 10 minutes, remove the glasses from the refrigerator and freezer. Line up the three glasses on the table and record your observations.

ACTIVITY TWO

What You Need:

·         An empty glass jar with a metal top

·         Hot tap water

·         Ice cubes

Tip: Be patient. It takes about 15 minutes for water drops to form.

Question: How can you make it rain indoors?

1) First, fill a glass jar with very hot tap water.

2) Then, flip the lid over and fill it with ice. Place the lid on top of the jar .

3) Now, wait and watch. In about 15 minutes you will see "rain" fall inside the jar .

A Scientific Explanation:
Some of the hot water turns into steam and collects on the lid. The ice cools the steam and turns it back into a liquid. When enough liquid collects on the lid it falls as a "rain" drop. This process is known as condensation .

EXTRA! EXTRA!
Look for other examples of condensation such as water drops forming on the side of a cold soft drink can. Use what you've learned about condensation to explain your observations.
