But if the salt has lost it’s savor

  1. 1. But if the salt has lost it’s savor….. Patrick Peyton Education 373 Spring 2010
  2. 2. Science Standard <ul><ul><ul><li>4.3.3 Identify salt as the major difference between fresh and ocean waters. </li></ul></ul></ul><ul><li>http://dc.doe.in.gov/Standards/AcademicStandards/StandardSearch.aspx </li></ul>
  3. 3. Definitions <ul><ul><ul><li>Salt -a crystalline compound, sodium chloride, NaCl, occurring as a mineral, a constituent of seawater, etc., and used for seasoning food, as a preservative, etc. </li></ul></ul></ul><ul><ul><ul><li>Fresh Water -water that does not contain a large amount of salt. </li></ul></ul></ul><ul><ul><ul><li>Ocean -the vast body of salt water that covers almost three fourths of the earth's surface. </li></ul></ul></ul>
  4. 4. Background Information <ul><ul><ul><li>Salt is in every ocean on Earth. Earth is made up of 71% Ocean water. Fresh Water makes up only 2% of Earth’s water supply! </li></ul></ul></ul>
  5. 5. Materials <ul><li>One dozen eggs </li></ul><ul><li>4 bowls </li></ul><ul><li>Salt </li></ul><ul><li>Tablespoons </li></ul><ul><li>Partner </li></ul><ul><li>Bottled water or Warm Tap water </li></ul>
  6. 6. The Problem <ul><li>We all know that salt water and fresh water have major differences. </li></ul><ul><li>What if we were to study which one was to effect the flotation of objects. </li></ul><ul><li>Which kind of water will make something float, salt water or freshwater? </li></ul>
  7. 7. Hypothesis <ul><li>Record your hypothesis in the journal provided, be specific. </li></ul><ul><li>Don’t worry about whether it is right or wrong that is why we are experimenting! </li></ul>
  8. 8. Procedure <ul><li>Step 1: Fill one bowl full of water and the other half full of water. </li></ul><ul><li>Step 2: Designate the full glass as “fresh water” and the half full glass as “saltwater.” </li></ul><ul><li>Step 3: Take 5-8 tablespoons of salt and add it into the glass of water designated for saltwater. Stir this glass well so the salt mixes in. </li></ul>
  9. 9. Procedures (cont’d) <ul><li>Step 4: Take out two eggs from the carton and place one into each separate glass. </li></ul><ul><li>Step 5: Record your observations in the table of the journal. </li></ul>
  10. 10. Conclusion <ul><li>What can you can conclude from this experiment? </li></ul><ul><li>Why is that it floats in one particular water and not the other? </li></ul><ul><li>Do you think this can apply in large bodies of water as well? </li></ul>
