Unit 1 · 3 skills

The Earth's Crust

The Planet's Outer Layer

The official wording · 3 outcomes
1.1
Outer most layer of the planet Composed of a variety of igneous, metamorphic and sedimentary rocks thickest (deepest) in mountain regions
1.2
Two types of crust Oceanic (5-10 km) and continental (30-50 km)
1.3
Cycles: Rock, tectonic, and water

Key ideas

  1. The crust is the outermost, rocky layer of the planet.

  2. It is made of igneous, metamorphic, and sedimentary rocks.

  3. The crust is thickest (deepest) under mountain regions.

  4. Compared to the whole Earth, the crust is a thin layer.

  5. There are two types of crust: oceanic and continental.

Watch out for

  • Thinking the crust is the same thickness everywhere - it is thicker under mountains.
  • Thinking the whole Earth is solid rock like the crust - deeper layers are very different.
  • Thinking the crust is thicker under the ocean - it is thinner there.

Unit 2 · 3 skills

Changes in Earth Surface

Fast and Slow Changes

The official wording · 3 outcomes
2.1
Rapid changes caused by Volcanoes, earthquakes, landslides
2.2
Slow changes: weathering, erosion, and deposition from water, wind and ice
2.3
Forces changing Earth’s surface

Key ideas

  1. Some changes to the land happen quickly.

  2. Volcanoes erupt, adding new rock and reshaping the land.

  3. Earthquakes shake and crack the ground.

  4. Landslides move rock and soil down a slope suddenly.

  5. Weathering breaks rock into smaller pieces over time.

Watch out for

  • Thinking all land changes are slow - some happen in seconds.
  • Thinking earthquakes create new mountains instantly - they shake the ground; mountains build slowly.
  • Mixing up weathering (breaking) with erosion (carrying away).

Unit 3 · 4 skills

Rocks

Reading the Rocks

The official wording · 4 outcomes
3.1
Types of rocks: Sedimentary, igneous and metamorphic
3.2
Fossils: Evidence of the past Ex. Organisms and environments
3.3
Formation processes: Solidification of magma, Cooling of lava, Heat and pressure, Weathering, erosion, and deposition.
3.4
Physical properties such as colour, weight, density, grain size, texture

Key ideas

  1. Igneous rock forms when melted rock (magma or lava) cools and hardens.

  2. Sedimentary rock forms when layers of sediment are pressed together over time.

  3. Metamorphic rock forms when heat and pressure change an existing rock.

  4. Every rock belongs to one of these three groups.

  5. A fossil is the preserved trace or remains of a living thing from long ago.

Watch out for

  • Thinking all rocks form the same way - the three types form differently.
  • Thinking a rock can never change type - the rock cycle can change it over time.
  • Thinking fossils are the actual living creatures - they are preserved traces or remains.

Unit 4 · 2 skills

Minerals

Testing and Identifying Minerals

The official wording · 2 outcomes
4.1
Crystal structure, Mohs hardness scale, lustre, magnetism, streak, and electrical conductivity
4.2
Multiple properties of a given mineral can help to identify minerals: Ex. Streak, crystal structure, transparency/opaque, hardness, electrical conductor, magnetic

Key ideas

  1. Hardness (the Mohs scale) is tested by seeing what can scratch what.

  2. Streak is the colour of the powder a mineral leaves when rubbed on a tile.

  3. Lustre is how shiny or dull a mineral looks.

  4. Some minerals are magnetic or conduct electricity - useful tests too.

  5. One test alone often is not enough to identify a mineral.

Watch out for

  • Thinking a mineral's streak is always the same colour as the mineral - it can differ.
  • Thinking harder minerals are always heavier - hardness and weight are different properties.
  • Thinking colour alone identifies a mineral - many minerals share colours.

Unit 5 · 2 skills

Soils

How Soil Forms and What It's Like

The official wording · 2 outcomes
5.1
Weathering and soil formation: Weathering (breakdown), erosion (transportation), and decomposition of plant and animal remains
5.2
Physical properties: Texture, colour, porosity, capacity to hold water, ability to support growth of plants

Key ideas

  1. Weathering breaks rock into tiny pieces.

  2. Erosion moves those pieces and mixes them.

  3. Decomposition of dead plants and animals adds nutrients to the mix.

  4. Together, over a long time, these make soil.

  5. Soil has texture - it can be sandy, silty, or clay-like.

Watch out for

  • Thinking soil is only crushed rock - it also contains decomposed living matter.
  • Thinking soil forms quickly - it forms very slowly.
  • Thinking all soil is the same - soils differ in texture and water-holding.

Unit 6 · 2 skills

Uses of Earth Resources

Using Earth's Resources Wisely

The official wording · 2 outcomes
6.1
Characteristics of natural resources make them useful in products and materials
6.2
Renewable (Ex. Sunlight, air, plants, animals, and water) versus non-renewable (Ex. Coal, oil, and natural gas)

Key ideas

  1. A natural resource is something from the Earth that people use.

  2. A resource's characteristics decide what it is good for.

  3. Rocks, minerals, soils, and fossil fuels are all natural resources.

  4. We choose materials based on their useful properties.

  5. A renewable resource can be replaced in a short time (sunlight, air, water, plants, animals).

Watch out for

  • Thinking every resource is useful for everything - properties decide the use.
  • Thinking resources are unlimited - many are limited.
  • Thinking renewable means unlimited - renewable resources can still be overused.
