X-Stream Puzzle


Students will review the food chain in a stream ecosystem. Using a puzzle, students will learn that all the organisms in the stream are connected and that humans are part of the chain. Ultimately, humans can have both a positive and negative influence on streams.


Life Systems, Grade 4 (Habitats and Communities)

Plants and animals are interdependent and are adapted to meet their needs from the resources available in their particular habitats.
Changes to habitats (whether by nature or human means) can affect plants and animals and the relationship between them.
Society relies on plants and animals

  1. analyse the effects of human activities on habitats and communities;
  2. investigate the interdependence of plants and animals within specific habitats and communities;
  3. demonstrate an understanding of habitats and communities and the relationship among the plants and animals that live in them

1.2   identify reasons for the depletion or extinction of a plant or animal species(eg. hunting, disease, invasive species) evaluate the impacts on the rest of the natural community and propose possible actions for preventing the depletion or extinction from happening.

3.3 identify factors (eg. availability of water or food, amount of light, type of weather) that affect the availability of plants and animals to survive a specific habitat.

3.4 demonstrate an understanding of a community as a group of interacting species sharing a common habitat (eg. the life in a meadow, a patch os forest or a stream)
