We refer to our planet as “planet earth,” but we should probably call it “planet ocean.” It is, after all, 70% covered with water, mostly saltwater. Water is essential to all life. Without it, plants and animals could not exist. In fact, most living organisms consist primarily of water. Humans are about 60% water and jellyfish are about 95% water. That is the same water content of a cloud!
God created the waters even before the land (Genesis 1:2, 9). That same water that God created in the beginning is still here. We do not “lose” or “gain” water. It is simply recycled. Some water has been lost from the earth as a result of man’s space explorations. But, that accounts for very little loss. And we don’t have a pipeline coming to earth from some far away planet to replenish our water. So the water we now wash our hands with is the same water Pilate used to wash his hands. We drink the same water that Napoleon drank.
Water is water. It is used and then recycled as it evaporates from the earth and then returns in some form of precipitation. Vast quantities of water evaporate from seas and lakes to form clouds that move over the earth, rise, cool, and condense back into a liquid to be released onto the earth.
This is “fresh” water since it contains no salt. It falls to earth, soaks into the ground, and eventually runs back into the seas. We will never run out of water. We have all the water we could ever use. But there is one little problem with ocean water – it contains about 3.5% salt. We cannot use it until all the salt has been removed. And desalinating water can be very expensive.
To teach students to conserve water and use it wisely, we make a “water cycle bracelet” to illustrate the recycling principle.
Water Cycle Bracelet
All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, there they return again. Ecclesiastes 1:7. This verse describes the water cycle that God put in motion to provide us with an unending source of life-giving water. This bracelet reminds us of God’s plan and care for us.
Supplies Needed: Elastic cord or string and two beads of each color listed below.
Directions: Thread one set of beads onto cord in the order listed. Repeat to represent the water cycle repeating over and over. Tie knot in cord and trim excess. Wear the bracelet proudly, and share the information about God’s plan for water!
If you’d like to learn more about water and the awesome animals that God made to live in it, our book The Complete Aquarium Adventure includes lots of information as well as reproducible activities and projects to help you!
I am excited to welcome back guest authors Bill and Merilee Clifton. Bill, a former evolutionist, has a passion for God’s creation! His desire is to share his knowledge of science and the Bible to help others understand our incredible Creator and His handiwork. For over 30 years, Bill has taught various science, Bible, and creationism classes for public, Christian, and home schools. He was head of the Education Department of SeaWorld Orlando and served as Minister of Education in a local church before he and his wife Merilee founded Science Partners in 2000. They offer creation-based science classes for homeschoolers; lead Creation Adventures (field trips and workshops) for homeschool families, Christian schools, and churches; and Bill is a creation speaker. You can learn more about the Cliftons and their classes atwww.sciencepartners.net. You can read a previous guest post from the Cliftons here – Science Matters.
