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?

Living Things

  • observe and describe the characteristics of living and non-living things
  • observe the needs of living things that enable them to stay healthy
  • take responsibility for living things found in his or her environment.
  • identify the parts of plants that are used by other living things (for example, for food, shelter, tools)
  • be aware of the role of plants in sustaining life (for example, providing oxygen, food)
  • show responsibility when caring for plants.

Materials and Matter

  • use senses to describe observable properties of familiar materials (including solids, liquids, gases)
  • describe observable changes (including changes of state) that occur in materials
  • recognize that materials can be solid, liquid or gas
  • be aware of how to change water into a solid, liquid and gas
  • apply understanding of basic properties of materials in order to match materials to purpose (for example, waterproofing, insulating).


  • Observe carefully in order to gather data.
  • Plan and carry out systematic investigations, manipulating variables as necessary.
  • Make and test predictions.
  • Interpret and evaluate data gathered in order to draw conclusions.
