PYP3 (Grade 3) Science

The science component of the PYP is characterized by concepts and skills rather than by content. Therefore, OurPlanet ensures that a breadth and balance of science content is covered through the units of inquiry. The knowledge component of science in the PYP is arranged into four strands: 

  • Living things
  • Earth and Space
  • Materials and Matter
  • Forces and Energy.

What will students will be working on this year?

Earth and space (Age 7-9)

  • describe how water sustains life
  • analyse systems of water storage and usage, both natural and human-made
  • explain why fresh water is a limited resource
  • identify water issues and propose solutions for responsible, equitable water use (for example, desalination).

Materials and matter (Age 7-9)

  • investigate how buildings and other structures stand up (for example, piles, buttresses, I-beam girders)
  • investigate the construction of a building or structure and identify the materials used
  • critique the impact of a structure on the natural environment
  • explain people’s responsibility regarding the use of materials from the environment.


  • Observe carefully in order to gather data.
  • Identify or generate a question or problem to be explored.
  • Use a variety of instruments and tools to measure data accurately
  • Plan and carry out systematic investigations, manipulating variables as necessary.
  • Make and test predictions.

Interpret and evaluate data gathered in order to draw conclusions.
