TOPIC 1:
The Structure of the Earth
Lesson 1:
The Planet Earth
This lesson introduces the fundamentals of
Earth as a planet, including its formation, position within the solar system,
and essential characteristics. Students will understand the significance of
Earth's shape (geoid), size, and how its rotation and revolution create day,
night, and seasons.
Lesson 2:
The Exterior and Interior of the Earth
Students explore the Earth's structure,
focusing on the distinct layers: crust, mantle, and core. The lesson explains
the composition, thickness, and states of matter (solid or liquid) within each
layer, providing insights into Earth's dynamic nature, including tectonic
movements.
Lesson 3:
Volcanoes
This lesson covers the basics of volcanoes,
explaining their formation, typical locations, and types of eruptions. Students
learn how tectonic plate movements lead to volcanic activity, and they explore
the relationship between plate boundaries and volcanic hotspots.
Lesson 4:
Types of Volcanoes
Students dive deeper into the different types
of volcanoes: shield, cinder cone, and composite. The lesson discusses the
characteristics of each type, including shape, size, and eruption style, along
with real-world examples from around the globe.
TOPIC 2:
Rock Cycle and Weathering
Lesson 5:
Sedimentary Rocks
This lesson explains the formation of
sedimentary rocks from accumulated sediments through processes like compaction
and cementation. Students learn about different types of sedimentary rocks,
such as sandstone, shale, and limestone, and their formation environments.
Lesson 6:
Igneous Rocks
Students explore igneous rocks formed from the
cooling and solidification of magma or lava. The lesson distinguishes between
intrusive (plutonic) and extrusive (volcanic) igneous rocks, providing examples
like granite and basalt, and explaining their formation processes.
Lesson 7:
Metamorphic Rocks
This lesson covers the formation of
metamorphic rocks under extreme heat and pressure, altering the structure and
mineral composition of pre-existing rocks. Students learn about common
metamorphic rocks such as marble and slate, and the processes that lead to
their transformation.
Lesson 8:
Physical Weathering
Students are introduced to physical
weathering, which breaks down rocks into smaller pieces without altering their
chemical composition. The lesson covers processes like freeze-thaw cycles,
abrasion, and the impact of plant roots on rock disintegration.
Lesson 9:
Chemical Weathering
This lesson explains chemical weathering,
where minerals in rocks undergo chemical changes, leading to decomposition.
Students learn about reactions such as oxidation, hydrolysis, and carbonation,
and their effects on different types of rocks.
TOPIC 3:
Structure of the Atmosphere
Lesson 10:
Layers of the Atmosphere
Students explore the Earth's atmosphere,
breaking it down into its five main layers: the troposphere, stratosphere,
mesosphere, thermosphere, and exosphere. The lesson details the characteristics
of each layer, including temperature variations, atmospheric phenomena, and the
role of the ozone layer.
Lesson 11:
The Properties of Air
This lesson introduces students to the basic
properties of air, including its composition, density, and the concept of air
pressure. Students also learn how air pressure changes with altitude and
temperature, and how these variations affect weather and breathing.
Lesson 12:
Atmospheric Pressure
Students delve deeper into atmospheric
pressure, learning how it is measured and influenced by altitude, temperature,
and humidity. The lesson covers the use of barometers and explains how pressure
differences drive weather patterns and wind formation.
Lesson 13:
The Moving Air
This lesson explores the movement of air
within the atmosphere, focusing on concepts like wind, the Coriolis effect, and
global wind patterns. Students learn how these movements influence climate,
weather, and the distribution of heat around the planet.
TOPIC 4:
Weather
Lesson 14:
Convection Currents
Students learn about convection currents,
which are caused by temperature differences in the atmosphere and oceans. The
lesson explains how these currents contribute to weather phenomena like
thunderstorms and oceanic circulation, and their impact on global climate.
Lesson 15:
Precipitation
This lesson introduces the various forms of
precipitation—rain, snow, sleet, and hail—and the atmospheric conditions that
lead to their formation. Students learn about the water cycle, cloud formation,
and the tools used to measure precipitation.
Lesson 16:
Clouds and Cloud Types
Students study cloud classification based on
appearance and altitude, focusing on cloud types like cumulus, stratus, and
cirrus. The lesson explains how different cloud types are associated with
specific weather conditions and their role in the water cycle.
Lesson 17:
Weather Charts
This lesson teaches students how to read and
interpret weather charts, which display data on temperature, pressure, wind
speed, and precipitation. Students learn the symbols and terminology used in
weather maps, enabling them to understand and predict weather patterns.
Lesson 18:
Weather Forecasting and Reporting
Students explore the tools and methods used in
weather forecasting, such as satellites, radar, and computer models. The lesson
emphasizes the importance of accurate weather predictions for safety, planning,
and understanding environmental changes.
Lesson 19:
Climate
This lesson differentiates between weather and
climate, explaining how long-term patterns of temperature, precipitation, and
other factors determine climate. Students learn about Earth's various climate
zones, the factors that influence them, and the growing concern of climate
change.
