  1. Water Water Everywhere Lab OBJECTIVES: Describe the amount and distribution of water on the Earth in oceans, rivers, lakes, groundwater, icecaps, and the atmosphere. Calculate water volumes using percentages.

  2. Materials MATERIALS: 1000 ml container (Fill with 1000 ml of water) 50ml graduated cylinder 2 Plastic droppers 3 - 10 ml graduated cylinders or beakers Food Coloring

  3. Copy this chart on your own paper

  4. Directions – Listen Carefully • Column 1: First determine the amount of water you would like to represent each of the 7 bodies of water (Based of 1000ml). • Column 2: Then convert to a percentage (your estimate/total) x 100 = % • Column 3 & 4: At the end I will give you the actual amounts to complete the table. From there you will rank them 1 representing the most water.

  5. Write Out Questions and Answer • What fraction of the earth’s surface is covered in water? • What percentage of all the Earth’s water is in a form that is useable to humans and land animals? • Is the amount of water on Earth always changing or is it a constant amount? • Produce a sketch of the water cycle. (Include vocabulary terms) • Provide at least two reasons why cycling of water is important to living organism. (Not they drink it)

  6. Actual Amounts

  7. Answers to Post Lab • What fraction of the earth’s surface is covered in water? 70% • What percentage of all the Earth’s water is in a form that is useable to humans and land animals? 1% • Is the amount of water on Earth always changing or is it a constant amount? Constant
