    Essential Learning Outcomes

    ELO-1
    Plan and conduct an investigation to determine if plants need sunlight and water to grow.

    Students explore plant needs through hands-on investigations, observing and recording how plants grow under different conditions. They learn about plant parts, seed structure, germination stages, and conduct controlled experiments to determine optimal growing conditions.

    Students will:

    Students will define key terms related to plant growth, name parts of seeds and their functions, explain how to design controlled experiments, account for differences in plant growth rates under varying conditions, and understand the stages of germination.

    Learning Outcomes:

    ELO-2
    Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

    Students explore the interdependent relationships between plants and animals, focusing on how animals help plants reproduce through seed dispersal and pollination. They make observations of plants and animals to compare the diversity of life in different habitats.

    Students will:

    Students will discuss how fruit trees grow and how seeds make new plants, compare different forms of seed dispersal by animals, show finished models that mimic animal functions in dispersing seeds or pollinating plants, identify parts of flowers that aid in pollination, and account for how invasive plant species might impact habitats.
