Attachments

Student Prior Knowledge:
Students should have a basic understanding of the water cycle.

Instructional Procedures:

  1. Prepare a mixture of dirty water in a large bucket. Some possible things to add include, sand, clay, detergent, food particles etc.
  2. You may want to make an overhead of the lab set up to help them
  3. Supervise as they set up their labs.
  4. When you light their burners remind them to heat slowly, if their boil becomes to large the water will move through their plastic piping instead of evaporating and then condensing.
  5. Make sure that students wear their goggles throughout the lab
  6. Monitor students closely

Extensions:
Use a voltmeter to determine the cleanliness of water. Pure water will not conduct a current.
