Grade 3

Science and Technology: Understanding Earth and Space Systems

Overall Expectations
▪ Assess the impact of soils on society and the environment, and of society and the environment on soils
▪ Investigate the composition and characteristics of different soils
▪ Demonstrate an understanding of the composition of soils, the types of soils, and the relationship between soils and other living things

Specific Expectations
▪ 1.2 – Assess the impact of human action on soils, and suggest ways in which humans can affect soils positively and/or lessen or prevent harmful effects on soils
▪ 2.2 – Investigate the components of soil, the condition of soil, and additives found in soil, using a variety of soil samples from different local environments, and explain how the different amounts of these components in a soil sample determine how the soil can be used
▪ 3.1 – Identify and describe the different types of soils
▪ 3.2 – Identify additives that might be in soil but that cannot always be seen
▪ 3.4 – Describe ways in which the components of various soils enable the soil to provide shelter/homes and/or nutrients for different kinds of living things

Grade 4

Specific Expectations
▪ Follow established safety procedures for working with soils and natural materials

Grade 5-6

Overall Expectations
▪ Analyse the immediate and long-term effects of energy and resource use on society and the
environment, and evaluate options for conserving energy and resources

Specific Expectations
▪ Analyse the long-term impacts on society and the environment of human uses of energy
and natural resources, and suggest ways to reduce these impacts
▪ Describe chemical changes in matter as changes that are irreversible

Grade 7

Overall Expectations
▪ Assess the impacts of human activities and technologies on the environment, and evaluate ways of controlling these impacts
▪ Investigate interactions within the environment, and identify factors that affect the balance
between different components of an ecosystem

Specific Expectations
▪ Design and construct a model ecosystem and use it to investigate interactions between the biotic and abiotic components in an ecosystem
▪ Demonstrate an understanding of an ecosystem as a system of interactions between living organisms and their environment
▪ Identify biotic and abiotic elements in an ecosystem, and describe the interactions between them
▪ Describe the roles and interactions of producers, consumers, and decomposers within an ecosystem
▪ Describe how matter is cycled within the environment and explain how it promotes sustainability

Grade 8

Overall Expectations
▪ Assess the personal, social, and/or environmental impacts of a system, and evaluate improvements to a system and/or alternative ways of meeting the same needs
▪ Investigate a working system and the ways in which components of the system contribute to its desired function

Grade 3

Specific Expectations
▪ Divide whole objects and sets of objects into equal parts, and identify the parts using fractional
names

Grade 4

Specific Expectations
▪ Compare and order fractions (i.e., halves, thirds, fourths, fifths, tenths) by considering the size
and the number of fractional parts
▪ Demonstrate and explain the relationship between equivalent fractions, using concrete
materials (e.g., fraction circles, fraction strips, pattern blocks) and drawings
▪ Represent fractions using concrete materials, words, and standard fractional notation
