Earth and Space Systems, Grade 2 (Air and Water in the Environment)
Air and water are a major part of the environment. Living things need air and water to survive. Changes to air and water affect living things and the environment. Our actions affect the quality of air and water, and its ability to sustain life.
1. assess ways in which the actions of humans have an impact on the quality of air and water, and ways in which the quality of air and water has an impact on living things
Earth and Space Systems, Grade 3 (Soil in the Environment)
Soil is made up of living and non-living things. The composition, characteristics, and condition of soil determine its capacity to sustain life. Soil is an essential source of life and nutrients for many living things. Living things, including humans, interact with soils and can cause positive or negative changes.
1. assess the impact of soils on society and the environment, and of society and the environment on soils;
2.investigate the composition and characteristics of different soils;
3. demonstrate an understanding of the composition of soils, the types of soils, and the relationship between soils and other living things.
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
Matter and Energy, Grade 5 (Properties of and Changes in Matter)
There are three states of matter. Matter that changes state is still the same matter. Physical change refers to the fact that a substance can be changed from one form to another. Chemical change implies the formation of a new substance. The properties of materials determine their use and may have an effect on society and the environment.
1. evaluate the social and environmental impacts of processes used to make everyday products;
2. conduct investigations that explore the properties of matter and changes in matter;
3. demonstrate an understanding of the properties of matter, changes of state, and physical and chemical change.
