Science 2

Unit 1: Living Things: Life Cycles

Big Idea: living things have life cycles adapted to their environment. Some life cycles change shape completely (like a caterpillar to a butterfly) and some just grow bigger (like a puppy to a dog); offspring look like their parents but not exactly the same; First Peoples have long observed and used their knowledge of these life cycles.

• Big-change and small-change life cycles

• How offspring are like and unlike their parents

• How First Peoples use life cycle knowledge

Unit 2: Materials and Forces

Big Idea: everyday materials can be changed through physical and chemical processes, and forces influence the motion of an object. Warming, cooling, cutting, bending, stirring, and mixing change a material without making a new one; cooking and burning make a brand-new material; contact forces, at-a-distance forces, and balanced or unbalanced forces make things move, stop, speed up, slow down, or change direction.

• Physical changes — same material, new shape

• Chemical changes — a brand-new material

• Different kinds of forces

Unit 3: Water in Our World

Big Idea: water is essential to all living things, and it cycles through the environment. Water comes from local sources like oceans, lakes, rivers, wells, and springs; it must be conserved because fresh water is limited; it travels in a repeating cycle of evaporation, condensation, precipitation, and runoff; and First Peoples hold deep knowledge of local water systems and their connections.

• Local water sources and watersheds

• Ways to save water

• How water travels in a cycle

• First Peoples knowledge of water cycles, conservation, and connections
