How Clear is Your Lake?

Theme:Water Science
Location:Waterfront (Under Shelter)
Map #:8

Purpose

A hands-on activity where students learn about water clarity and the role algae plays in a lake ecosystem.  Students will use a secchi disk to measure water clarity in their “mini lake”.  Participants are encouraged to ask questions.

Presented by the Dorset Environmental Science Centre, Ministry of Environment.

Ontario Curriculum Connections

Science and Technology:
  • Understanding Life Systems, Grade 4 (Habitats and Communities)
    • identify factors that affects 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 a community as a group of interacting species sharing a common habitat
    • describe structural adaptations that allow plants and animals to survive in specific habitats
    • identify reasons for the depletion or extinction of a plant or animals species (e.g. changes in or destruction of its habitat), evaluate the impacts on the rest of the natural community, and propose possible actions for preventing such depletions or extinctions from happening
    • describe structural adaptions that allow plants and animals to survive in specific habitats
    • explain why changes int he environment have a greater impact on specialized species than on generalized species
  • Understanding Life Systems, Grade 6 (Biodiversity)
    • describe ways in which biodiversity within and among communities is important for maintaining the resilience of these communities
    • describe interrelationships within species, between species and between species and their environment, and exp,lain how these interrelationships sustain biodiversity
    • demonstrate an understanding of biodiversity as the variety of life on earth, including variety within each species of  plant and animal, among species of plant and animal, among species of plants and animals in communities, and among communities and the physical landscapes that support them
    • describe ways in which biodiversity within and among communities is important for maintaining the resilience of these communities
