Grade 3 – Earth and Space Systems
Lesson Summary: Students will create an animated story that demonstrates the different kinds of soil in Ontario and/or
how to protect the soil.
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.

of soils and/or lessen or prevent
harmful effects on soils
E2.1 identify the living and non-living
components of soil, and describe the
characteristics of healthy soil
E2.3 examine different types of soils
found in Ontario, and describe how
different soils are suited to growing
different types of food, including crops
E2.5 identify various strategies used to
maintain and improve soil health in
Ontario
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,
and repeating events
C3.2 read and alter existing code,
including code that involves
sequential, concurrent, and
repeating 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 sen- tences 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
Breaking Down the Coding Expectations in Science & Technology:
In the Grade 3 Science & Technology curriculum, there are 2 coding related expectations:
A2.1 write and execute code in investigations and when modelling concepts, with a focus on testing,
debugging, and refining programs
A2.2 identify and describe impacts of coding and of emerging technologies on everyday life
To paraphrase these expectations and express them in plainer language, students are being asked to:
● write code to demonstrate a science-related concept, focusing on testing their code to identify issues, correct
those issues, and further improve their code
● show how coding impacts our lives
Both expectations will be addressed through the project.
Learning Goals: We are learning to write code to create an animated story that demonstrates the different kinds of soil
in Ontario and/or how to protect the soil.
Success Criteria:
1. I can use a variety of event blocks and movement blocks
2. I can use loops to make my code more efficient
3. I can use sprite costumes to create animation effects
4. I can explain the testing and debugging process in my own words
5. I can show different kinds of soil and/or ways to protect the soil
STEM Profile:
Mary C. Baltz (1923-2011) was an American soil scientist and the first
woman ever assigned in the field for the Soil Conservation Service,
who make sure the soil stays healthy.
After graduating from Cornell University, she joined the Soil Survey as
a Junior Soil Surveyor and was eventually promoted to a Survey Party
Chief. She was responsible for soil mapping on farms in different
counties and was later assigned to do a map measurement for all of
New York. Mary hired a team of women to work with her, showing
the importance of getting more women involved in STEM.
Like Mary, we will be helping others better understand soil and how
to keep it healthy.
Minds On:
1. Students will have different experience levels when it comes to coding.
a. If students have never experienced coding before, please watch the “What is Coding?” video.
b. If students have experienced coding before, have a quick discussion in which students share their definition
of coding. Some responses to look for include:
i. Coding is the language that computers speak
ii. Coding is how we talk to computers or get computers to do what we want
iii. Coding is the instructions that we give to a computer
2. Introduce the idea of a loop, which is a repeating section of code used to make the code more efficient; for example,
both of the following stacks of code do the same thing (i.e., have a sprite draw a square). Which is more efficient?
