Questions About Oceans or Saltwater
Design your own experiment based on the activities conducted for the following outcomes:
  • Explain that evaporation can separate the water from the salt in salt water.
  • Compare the basic properties of fresh and salt water (e.g., density, ability to dissolve salt, freezing point).
  • Describe the connections between the salt water found in the ocean and the fresh water in the water cycle.
  • Think about the concepts and what else students might want to learn.
After completing this activity, students should be able to design a simple experiment to answer a question they have about the ocean or saltwater. Grade level: K-4.
