Properties of Water


  • Water has many different characteristics that affect how it will react to environmental changes and how organisms survive within it. Here are 2 different experiments that you can do to investigate the properties of salt and freshwater.


Complete the two experiments attached to the right-hand side of the page:

Which Melts Fastest?

Sea and Ice Salinity


  • What different qualities does water have? How do we interact with these different qualities? 
  • How do the changes in water phases affect people? What happens if our drinking water is all evaporated, or frozen? 
  • How might other communities be affected by melting water? What baout 

Complete a blog describing your findings and the differences you notice between salt and freshwater

Once you have completed your blog, you may take the One Big Ocean Quiz to earn your first badge and complete the One Big Ocean principle.

Learning Objectives

To understand how the characteristics of salinity and temperature affect the properties of water

This activity may be used to support the following learning objectives and competencies 

GRADE LEVEL: Primary, Intermediate


K: Humans Interact with matter every day through familiar materials

1: Matter is useful because of its properties

1: Observable patterns and cycles occur in the local sky and landscape

2: Water is essential to all living things, and it cycles through the environment

3: Wind, water and ice change the shape of the land

3: Thermal energy can be produced and transferred

4: Matter has mass, takes up space and can change phase

6: Everyday materials are often mixtures

7: Earth and its climate have changed over geological time


Questioning and Predicting

  • Demonstrate curiosity and a sense of wonder about the world
  • observe objects and events in familiar contexts or unfamiliar contexts 
  • Make predictions about the findings of their inquiry 
  • ask simple questions about familiar objects and events 

Planning and Conducting

  • Make exploratory observations using their senses
  • safely manipulate materials
  • make simple measurements using non-standard units
  • Decide which variable should be changed and measured for a fair test

Processing and analyzing data and information

  • Experience and interpret the local environment
  • discuss observations
  • represent observations and ideas by drawing charts and simple pictographs 


  • Evaluate whether their investigations were fair tests
  • identify possible sources of error
  • suggestion improvements to their investigation methods
  • demonstrate an understanding and appreciation for evidence 
  • Identify the social, ethical, and environmental implications of the findings from their own and others investigations 

Applying and Innovating

  • Cooperatively design projects
  • Transfer and apply learning to new situations


    • share observations and ideas orally or in written form
    • express and reflect on personal experiences of place
