Grade 9 Science Q3 - Life Science
-featured.png)
This course blends genetics and ecology with a Philippine focus. Students will model DNA, study replication and mutations, evaluate biodiversity's role in ecosystem stability, map key local habitats, and research endangered Philippine species. Through diagrams, case studies, field surveys, and a community conservation project, learners develop scientific skills, critical thinking, and practical stewardship for further study or civic action.

What you'll learn
- Construct or interpret models and labeled diagrams representing the double helix structure of DNA (deoxyribonucleic acid) and explain the roles of DNA, genes, and chromosomes in the transmission of traits.
- Describe mutations as changes in DNA or chromosomes, discuss some of the factors that cause mutations (such as radiation or chemicals), and evaluate the beneficial, harmful, or neutral effects of these changes.
- Explain the advantage of high biodiversity in maintaining the stability of an ecosystem, particularly during challenging conditions like food shortages, disease outbreaks, or climate change.
- Classify animals and plants of the Philippines as critically endangered, endangered, or vulnerable species, and discuss as a class how threats to biodiversity can ultimately lead to species extinction.
- Describe and use labeled diagrams to illustrate the key biotic and abiotic features of major Philippine ecosystems, including tropical rainforests, mangrove forests, swamps, estuaries, and coral reefs.
- Describe the possible negative effects of human activities (e.g., deforestation, pollution) on ecosystems, and plan a survey to explore possibilities for minimizing the impact and conserving endangered species in the local community.
