Unit 1 – Minerals
This unit covers what minerals are and how they are identified, mined, and used.
Unit 2 – Rocks
This unit discusses the 'rock cycle,' as well as igneous, sedimentary, and metamorphic rock.
Unit 3 – Weathering and Soil
This unit discusses mechanical versus chemical weathering, properties of soil, and how climate affects soil.
Unit 4 – Erosion and Deposition
This unit discusses how the Earth's surface is built up and worn down, how water movement, waves, and wind shape
the land, and how glaciers change land by moving sediment.
Unit 5 – Plate Tectonics
This unit covers the composition versus the physical structure of the Earth, where the Earth's plates are located,
how the continents drift, the plate boundaries, and how Earth's crust is deformed.
Unit 6 – Earthquakes
This unit discusses what earthquakes are, how they are measured, and how to prepare for them.
Unit 7 – Mountains and Volcanoes
This unit discusses how mountains are formed, what happens when a volcano erupts, what causes an
eruption, and what types of volcanoes there are.
Unit 8 – Earth's Past
This unit discusses relative and absolute dating, types of unconformities and fossils, and the geologic
time scale.
Unit 9 – Natural Resources
This unit discusses renewable and non-renewable resources, with special emphasis on fossil fuels,
conservation and recycling. It also covers other energy sources.
Unit 10 – Earth's Fresh Waters
This unit covers the water cycle, and fresh water as a resource, frozen, and underground. Water
shortages are also discussed.
Unit 11 – Ocean Systems
This unit describes the Earth's oceans as connected systems, as well as the ocean floors, how ocean
water moves, what waves are and what they do, and what causes tides.
Unit 12 – Earth's Atmosphere
This unit discusses the composition of the atmosphere and its layers, air pressure, air quality and
pollution.

Unit 13 – Weather Factors
This unit discusses the energy that we get from the sun, how heat transfer works and what it does for
us, what wind is, the difference between local and global winds, and where the global wind belts are.
Also covered are humidity, types of clouds, and precipitation.
Unit 14 – Weather Patterns
This unit discusses types of air masses and how they move, as well as types of fronts. It goes on to cover
cyclones and anticyclones, thunderstorms, tornadoes, hurricanes, and snowstorms.
Unit 15 – Weather Predictions
This unit discusses weather forecasting and technology, and how to read a weather map.
Unit 16 – Earth in Space
This unit covers how Earth moves in space and it's seasons, gravity, and motion.
Unit 17 – Earth's Moon
This unit discusses the phases of the moon, the difference between lunar and solar eclipses, and the
surface, origin, and characteristics of the moon.
Unit 18 – Space Exploration
This unit discusses the history of rockets and how they work, multistage rockets, the space program,
working in space, and the challenges we face in space.
Unit 19 – The Sun
This unit discusses the Sun's interior, its atmosphere, and its features.
Unit 20 – Inner Planets
This unit discusses The Earth, Mercury, Venus, and Mars.
Unit 21 – Outer Planets – Gas Giants
This unit discusses the outer planets, including Jupiter, Saturn, Uranus, Neptune, and Pluto.
Unit 22 – Comets, Asteroids, and Meteors
This unit discusses comets, asteroids, and meteors.
Unit 23 – Telescopes
This unit discusses electromagnetic radiation, different types of telescopes, and observatories.
Unit 24 – Stars
This unit discusses the classification and lives of stars and how to measure the distance to stars,
as well as Hertzsprung-Russell diagrams, star systems, galaxies, and the expanding universe.
