    Study Notes

    Guide Card

    • Organisms constantly interact with each other and their environment to survive
    • Interactions are crucial for fulfilling basic needs like food, water, shelter, and finding mates
    • Organisms rely on each other for survival and support life on our planet
    • Ecological relationships, such as mutualism, predation, and competition, are key to survival.

    Main Objective

    • Understand how organisms interact with each other and their environment to survive.

    Sub-Objectives

    • Describe major ecological relationships (mutualism, predation, competition)
    • Predict how environmental factors like sunlight, water, and temperature affect ecosystems.

    Activity Card No. 1

    • Objective: Identify different types of organism interactions (mutualism, commensalism, parasitism, predation). Analyze who benefits, is harmed, or unaffected.
    • Concept: Focuses on identifying types of ecological interactions in ecosystems.

    Activity Card No. 2

    • Objective: Identify and describe different types of interactions between organisms in an ecosystem.
    • Objective: classify relationships as mutualism, commensalism, parasitism, or predation
    • Develop critical thinking skills by analyzing organism interactions in specific scenarios
    • Concept: This activity helps students classify interactions as mutualism, commensalism, parasitism, or predation.

    Activity Card No. 3

    • Title: Create Your Own Example
    • Objectives: Create examples of each relationship in real-world ecosystems; reflect on the role of these relationships in maintaining ecosystem balance

    Activity Card No. 4

    • Cognitive Objective: Identify and describe abiotic factors in an ecosystem.
    • Affective Objective: Appreciate the role of abiotic factors in supporting life within an ecosystem.
    • Psychomotor Objective: Complete a graphic organizer by listing down abiotic factors and sharing insights in small group discussions
    • Concept: This activity is about identifying and describing various abiotic factors in an ecosystem.

    Activity Card No. 5

    • Title: Flooding in the Philippines
    • Concept Impact of abiotic factors on ecosystems (flooding in the Philippines)
    • Objective: Understand how changes in abiotic factors can affect an ecosystem.
    • Procedure: Carefully examine images of flooding in the Philippines; answer questions about effects of the flooding on biotic and abiotic factors.

    Activity Card No. 6

    • Title: Analyzing and Predicting Ecosystem Changes
    • Concept: Focusing on ecosystem response to drought
    • Objective: Students identify how abiotic factors influence the survival of organisms in an ecosystem.
