1. Earth and Space Science · Students will demonstrate an understanding that all materials, energy, and fuels that humans use are derived from natural sources.

1. Natural resources: Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment

2. Earth and Space Science · Students will demonstrate an understanding of how the Earth's systems (i.e., geosphere, hydrosphere, atmosphere, and biosphere) interact in multiple ways to affect Earth's su

1. Earth's atmosphere: Develop a model to describe ways the geosphere, biosphere, hydrosphere, and atmosphere interact as connected Earth systems

3. Earth and Space Science · Students will demonstrate an understanding of the composition of Earth and the processes which change Earth's landforms.

1. Fast & Slow Earth Changes: Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)
2. Shapes of land and water: Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area

4. Earth and Space Science · Students will demonstrate an understanding of the various processes involved in the rock cycle, superposition of rock layers, and fossil formation.

1. Types of rocks: Use vocabulary for Earth's geological processes and rock types — igneous, sedimentary, metamorphic, erosion, weathering, deposition, fossil, sediment, strata, permeable, impermeable — and apply these when explaining how rocks form and how landscapes change over time
2. How fossils form: Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time

5. Physical Science · Students will demonstrate an understanding of magnets and the effects of pushes, pulls, and friction on the motion of objects.

1. Magnetic Materials: Observe how magnets attract or repel each other and attract some materials and not others

6. Physical Science · Students will demonstrate an understanding of the physical properties of matter to explain why matter can change states between a solid, liquid, or gas dependent upon the addition o

1. Heating & Cooling Changes: Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
2. Matter Is Made of Particles: Develop a model to describe that matter is made of particles too small to be seen, and that this explains properties of solids, liquids, and gases

7. Life Science · Students will demonstrate an understanding of how adaptations allow animals to satisfy life needs and respond both physically and behaviorally to their environment.

1. Variation & Survival Advantage: Use evidence to explain how variations in characteristics among individuals of the same species may provide advantages in surviving, finding mates, and reproducing
2. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time
3. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago

8. Life Science · Students will demonstrate an understanding that through reproduction, the survival and physical features of plants and animals are inherited traits from parent organisms but can also be

1. Inherited characteristics: Analyse and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms
2. Traits: inherited and environmental: Use evidence to support the explanation that traits can be influenced by the environment as well as inheritance
3. Offspring resemble parents: Observe that young plants and animals resemble their parents but are not identical, recognising inherited similarities and individual differences
