4th Quarter Topics: Grade 7 Science

UNIT 4: Earth & Space Module

The Philippine Environment

• Characteristics of the environment are influenced by the Philippines' location.
• Discussion involves latitude, longitude, and equator in determining a location on Earth.

Locating Places on Earth

• Use of coordinate systems (latitude and longitude) to locate places.
• Group activities to reinforce learning about geographic coordinate systems.
• Fun activities like treasure hunting to understand coordinates.

Geographic Coordinate System

• Describes location using degrees of latitude and longitude.
• Importance of knowing how to locate places using coordinate systems.
• Applications: GPS, digital mapping, and automotive navigation.

Location of the Philippines

• Described with respect to landmasses (Asia, Malay Peninsula, etc.) and bodies of water (South China Sea, Pacific Ocean).
• Activities to identify landmasses and bodies of water surrounding the Philippines.

Natural Resources of the Philippines

• Differentiation between renewable and nonrenewable resources.
• Importance of sustainable use of natural resources.
• Examples of natural resources: water, rocks, coal, etc.

Soil, Water, and Biodiversity

• Discussion on watersheds and their role in water distribution.
• Factors affecting watershed water amount: vegetation, slope, soil kind, and rainfall.
• High biodiversity with numerous endemic species in the Philippines.

Soil Formation

• Process involving weathering (mechanical and chemical) of rocks.
• Factors: temperature, rainfall, and biological action.

Rocks and Mineral Resources

• Historical use of rocks and the importance of mining for metals.
• Activity to locate mineral deposits in the Philippines and understand geological features.

Energy Resources

• Nonrenewable resources: coal, petroleum, natural gas, nuclear energy.
• Renewable resources: solar, geothermal, wind, biomass, water.
• Importance of energy conservation and sustainable practices.

Atmosphere and Climate

• Layers of the atmosphere: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
• How solar and lunar eclipses occur, and the impact of global warming.
• Greenhouse effect and its consequences on climate change.

Atmospheric Phenomena

• Explanation of land breezes, sea breezes, monsoons, and ITCZ.
• Seasonal changes explained through Earth's tilt and orbit.

Eclipses

• Types of solar and lunar eclipses and their occurrences.
• Impact of myths and facts associated with eclipses.

Seasons

• Explanation of why seasons change due to Earth's tilt and orbit.
• Different seasons in the Philippines and their characteristics.

Activities

• Various activities to reinforce concepts related to Earth's environment, resources, and astronomical phenomena.

Summary

• Recap of important concepts like locating places, natural resources, atmosphere layers, and climate effects.
• Encouragement of productive discussion and evaluation of scientific principles versus myths.
