Grade 4 – Life Systems
Lesson Summary: Students will choose a traditional First Nations, Métis or Inuit story about an animal and create a
public service announcement (PSA) to demonstrate how to protect the habitat of the animal in the story.
Curriculum Expectations: These expectations are intended to highlight the many ways in which this lesson could support
the curriculum. It is neither expected nor necessary for teachers to address all of these expectations at once. Teachers
are encouraged to select the most relevant expectations based on their unique context and intentions for the lesson.
Overall Expectations
A2. use coding in investigations and to
model concepts, and assess the impact
of coding and of emerging
technologies on everyday life and in
STEM-related fields
A3. demonstrate an understanding of
the practical applications of science
and technology, and of contributions
to science and technology from people
with diverse lived experiences
B1. assess impacts of human activities
on habitats and communities, and
analyse actions for minimizing negative
impacts and enhancing positive ones
B2. demonstrate an understanding of
habitats and communities and of
interrelationships among the
organisms that live in them
Specific Expectations
A2.1 write and execute code in
investigations and when modelling
concepts, with a focus on producing
different types of output for a variety
of purposes
A2.2 identify and describe impacts of
coding and of emerging technologies
on everyday life, including skilled
trades
A3.3 analyse contributions to science
and technology from various
communities
B1.1 assess positive and negative
impacts of human activities on habitats
and communities, while taking
different perspectives into account
B1.2 analyse the impact of the
depletion or extinction of a species on
its habitat and community, and
describe possible actions to prevent
such depletions or extinctions
B2.1 describe habitats as areas that
provide organisms, including plants
and animals, with the necessities of
life, and identify ways in which a local
habitat provides these necessities
Overall Expectations
C3. solve problems and create
computational representations of
mathematical situations using
coding concepts and skills
Specific Expectations
C3.1 solve problems and
create computational
representations of mathematical
situations by writing and executing
code, including code that
involves sequential, concurrent,
repeating, and nested events
C3.2 read and alter existing code,
including code that involves
sequential, concurrent, repeating,
and nested events, and describe
how changes to the code affect
the outcomes
Overall Expectations
1. Generate, gather, and organize
ideas and information to write for an
intended purpose and audience
2. draft and revise their writing, using
a variety of informational, literary,
and graphic forms and stylistic
elements appropriate for the purpose
and audience
Specific Expectations
1.1 identify the topic, purpose,
audience, and form for writing
1.2 generate ideas about a potential
topic, using a variety of strategies and
resources
1.3 gather information to support
ideas for writing in a variety of ways
and/or from a variety of sources
1.4 sort ideas and information for
their writing in a variety of ways
2.1 write short texts using a variety of
forms
2.3 use words and phrases that will
help convey their meaning as
specifically as possible
2.4 vary sentence structures and
maintain continuity by using joining
words (e.g., and, or) to combine
simple sentences and using words
that indicate time and sequence to
link sentences
3.4 use punctuation to help
communicate their intended
meaning, with a focus on the use of:
quotation marks to indicate direct
speech; commas to mark
grammatical boundaries within
sentences; capital letters and final
punctuation to mark the beginning
and end of sentences
3.8 produce pieces of published work
to meet identified criteria based on
the expectations related to content,
organization, style, use of
conventions, and use of presentation
strategies
