    • It's part of a larger program, DREAM+, designed to bridge learning gaps.
    • The resource is aimed at grade 9 students.
    • This program uses interactive sheets and educational video lessons.

    Volume 1: Volcanoes

    • The content is categorized into three lessons, each covering different aspects of volcanoes.
    • The lessons cover different volcano types, volcanic eruptions, and eruption preparedness.
    • The study material incorporates ICT integration, which allows access to educational video lessons via QR code.

    Learning Resource Management and Development System (LRMDS)

    • The LRMDS system publishes the interactive learning materials.
    • Section 9 of Presidential Decree No. 49 grants the government agency rights to not require copyright for the material.
    • The content can be adapted; the original source must be acknowledged.

    • Students will complete a pretest before each lesson.
    • Key vocabulary is introduced as word drills.
    • Activities are included for the students to engage with the concepts.
    • Activities include concept mapping, illustrations, and further investigation of volcano types and energy.

    Types of Volcanoes

    • The material covers different volcano types (e.g., composite, shield, cinder cone, fissure).
    • These types are based on their distinctive cones, volcanic eruptions patterns, and crater shapes.

    Types of Volcanic Eruptions

    • Four types of volcanic eruptions are covered: phreatic/hydrothermal, phreatomagmatic, strombolian, vulcanian, and plinian.
    • Each type is associated with unique characteristics in terms of water content, eruption style and size of ash columns.

    Energy from the Volcano

    • The book explores different ways of harnessing energy from volcanoes.
    • The process, including use of geothermal energy for electricity, is detailed.

    Volcanic Eruption Preparedness

    • The material provides valuable information about signs of impending eruptions.
    • Preparedness measures are outlined for volcano risk areas.
    • The need for an emergency kit is stressed.

    References

    • The list of references includes sources used in the creation of the learning materials (booklet).
