    Study Notes

    Recognizing Living Things

    • The lesson introduces the concept of the scientific method and its steps: observation, classification, inference, measurement, identification, hypothesis, experiment, conclusion, theory, and law.
    • The teacher uses instructional materials like a microscope, slides, and bread to further explain the lesson.

    Classification of Living Things

    • The lesson defines classification as grouping living things based on shared characteristics and introduces taxonomy, a branch of biology dedicated to classifying living things.
    • Carl Linnaeus, a Swiss scientist, introduced the system of classification in 1707-1778.
    • Reasons for classification are to:
      • Organize living organisms into groups
      • Facilitate identification of similar living things
      • Demonstrate relationships between different categories
      • Illustrate evolutionary trends
      • Make research and study easier
    • The lesson covers classification hierarchy (kingdom, phylum, class, order, family, genus, and species).
    • The lesson focuses on the classification of plants (Kingdom Plantae) and animals (Kingdom Animalia).
    • Kingdom Plantae includes the divisions: Bryophyta (mosses), Pteridophyta (ferns), Spermatophyta (seed-bearing plants), which can be classified into Angiosperm (flowering plants) and Gymnosperm (non-flowering plants).
    • Dicotyledonous plants have two seed leaves (cotyledons) and a tap root system.
    • Monocotyledonous plants have one seed leaf and a fibrous root system.
    • Kingdom Animalia is divided into Phyla:
      • Invertebrates: Porifera, Coelenterate, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, and Echinodermata.
      • Vertebrates: Chordata.
    • Phylum Porifera: Simple, aquatic, non-motile invertebrates found attached to rocks or shells, live in colonies, have motile larva, and are primitive multicellular animals (example: sponges).
    • Phylum Coelenterate: Multicellular organisms, have two layers of tissue, are mainly aquatic, possess radial symmetry, have tentacles with stinging cells, and include animals like jellyfish, sea anemones, and hydras.
    • Phylum Platyhelminthes (flatworms): Have bilateral symmetry, are triploblastic, most are parasitic, have a digestive tract with one opening, and have a nervous system.
    • Phylum Nematoda (roundworms): Unsegmented, cylindrical, triploblastic animals with a complete digestive tract and a nervous system.
    • Phylum Annelida (segmented worms): Have segmented bodies, a well-developed nervous system, a closed circulatory system, and a complete digestive tract.
    • Phylum Mollusca (mollusks): Have a soft body, a muscular foot, a mantle, most have a shell, and a complete digestive system.
    • Phylum Arthropoda (jointed-legged animals): Are the largest phylum in the animal kingdom with segmented bodies, jointed appendages, an exoskeleton, and a complex nervous system.
    • Phylum Echinodermata (spiny-skinned animals): Have radial symmetry, a spiny skin, a water vascular system, and include starfishes, sea urchins, and brittle stars.

    Evaluation and Assignment

    • The teacher evaluates the students by asking questions related to the content covered.
    • The students are assigned homework to further practice the material.
    • The teacher assigns work related to the lesson covered in each week to reinforce the concepts.
