Life Systems


Grade 3- Growth and Changes in Plants 
(Plants tough, have to link to zoo property)
– black walnut grove, creek walk/flood plain…

  1. Observe and investigate a wide variety of local plants, (from trees to mosses), in their natural environment.
  2. Plants important, not just as food and shelter for people and animals, but as suppliers of the world’s oxygen.


Overall Expectations:

  1. Understanding similarities and differences in the physical characteristics of different plant species and changes that take place as they grow.
  2. Requirements of plants and the effects of change in environmental conditions on plants.
  3. Describe ways in which plants are important to other living things, effects of human activities on plants.



1.  Monarch Rearing in classroom, planting milkweed at zoo and releasing butterflies at zoo, (or planting and releasing at local schoolyard).
–  Chart plant growth and plant consumption by caterpillars to calculate how much milkweed each caterpillar needs and therefore how much needed to plant/grow
– (Timing of caterpillar/plants crucial, would have to work with zoo for set days to visit.)
– preserving local endangered species, fighting climate change, restoring natural flora and fauna, working with local schools and students in education, working with community to strengthen zoo and community relationships.

2.  Constructing Animal Houses  – working with wood (use of plants), measurement, building habitat for animals temporary with possible reintroduction of plants to create natural habitat in the long run.


1.  Create a poster of animal/plant web – food relationships one colour, shelter relationships another colour.  (i.e.  white-tailed deer and cedar – shelter in winter, food source).
