This activity teaches water science and discusses the physics of how oxygen (and gases) become dissolved in water for animal and plant life. It encourages students to evaluate the structure of habitats and the aquatic ecosystem and how their everyday actions can have an impact on the natural environment.

Key Messages

  • Learn how plants and animals respire
  • Understanding the physics of natural gas diffusion
  • Understanding that even small changes in how we do things can conserve a lot of water

Ontario Curriculum Connections

Science and Technology:
  • Understanding the Life Systems, Grade 4 (Habitats and Communities)
    • analyze the positive and negative impacts of human interactions with natural habitats and communities, taking different perspectives into account, and evaluate ways of minimizing the negative impacts
    • identify reasons for the depletion or extinction of a plant or animal species (e.g. changes in or destruction of it's habitat), evaluate the impacts on the rest of the natural community, and propose depletions or extinctions from happening
    • identify factors that affect the ability of plants and animals to survive in a specific habitat
    • demonstrate an understanding of habitats as areas that provide plants and animals with the necessities of life
    • demonstrate an understanding of community as a group of interacting species sharing a common habitat
    • describe structural adaptations that allow plants and animals to survive in specific habitats
    • explain why changes in the environment have a great impact on specialized species than on generalized species
    • demonstrate an understanding of why all habitats have limits to the number of plants and animals they can support
  • Understanding Life Systems, Grade 6 (Biodiversity)
    • describe interrelationship within species, between species and between species and their environment, and explain how these interrelationships sustain biodiversity
