B1.1 describe changes or problems that could result from the loss of living and non-living things that are part of everyday life, while taking different perspectives into consideration

B2.3 identify the physical characteristics of various plants and animals, including humans, and explain how these characteristics help the plants and animals meet their basic needs

B2.5 describe the characteristics of a healthy environment, including clean air and water and nutritious food, and how a healthy environment enables living things to meet their needs

B1.2 assess impacts of various human activities on animals and the places where they live, and describe practices that can minimize negative impacts

B2.3 describe the life cycle of a variety of animals, including insects, amphibians, birds, and mammals

B2.5 describe adaptations, including physical and/or behavioural characteristics, that allow various animals to survive in their natural environment

B1.2 assess ways in which human activities have an impact on plants and plant habitats, and identify personal actions that they could take to minimize harmful effects and enhance positive ones

B2.1 describe the basic needs of plants, including the need for air, water, light, heat, nutrients, and space, and identify environmental conditions that may threaten plant survival

B2.4 describe ways in which a variety of plants adapt and/or react to their environment and to changes in their environment

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

B2.4 demonstrate an understanding of a food web as the interconnection of multiple food chains in a natural community

B1.1 assess the benefits of biodiversity and the consequences of the diminishing of biodiversity

B2.1 describe the distinguishing characteristics of different groups of organisms, and use these characteristics to further classify these organisms using a classification system

B2.5 describe interrelationships within species, between species, and between species and their natural environment, and explain how these interrelationships sustain biodiversity

B2.1 explain that an ecosystem is a network of interactions among living organisms and their environment

B2.5 describe how matter is cycled within the environment, and explain how the cycling of matter promotes sustainability

B2.6 explain the differences between primary succession and secondary succession in ecosystems

E2.1 identify the states of water on Earth’s surface, their distribution, relative amounts, and circulation, and the conditions under which they exist

E2.5 explain changes in atmospheric conditions caused by the presence of bodies of water

E2.6 describe various indicators of water quality, and explain the impact of human activity on those indicators

B1. assess the impact of human activities on the sustainability of terrestrial and/or aquatic ecosystems, and evaluate the effectiveness of courses of action intended to remedy or mitigate negative impacts;

B2. investigate factors related to human activity that affect terrestrial and aquatic ecosystems, and explain how they affect the sustainability of these ecosystems;

B2. investigate, through laboratory and/or field activities or through simulations, the principles of scientific classification, using appropriate sampling and classification techniques;

B3. demonstrate an understanding of the diversity of living organisms in terms of the principles of taxonomy and phylogeny.
