Science Standards of Learning for Third Grade

Scientific Investigation, Reasoning, and Logic

3.1  The student will plan and conduct investigations in which
     * questions are developed to formulate hypotheses;
     * predictions and observations are made;
     * data are gathered, charted, and graphed;
     * objects with similar characteristics are classified into at least two sets and two subsets;
     * inferences are made and conclusions are drawn;
     * natural events are sequenced chronologically;
     * length is measured to the nearest centimeter;
     * mass is measured to the nearest gram;
     * volume is measured to the nearest milliliter and liter;
     * temperature is measured to the nearest degree Celsius; and
     * time is measured to the nearest minute.

Living Systems  Power Point Presentation

3.5  The student will investigate and understand relationships among organisms in aquatic and terrestrial food chains.  Key concepts include
     * producer, consumer, decomposer;
     * herbivore, carnivore, omnivore; and
     * predator - prey.
3.6  The student will investigate and understand that environments support a diversity of plants and animals that share limited resources.  Key concepts include
     * water-related environments (pond, marshland, swamp, stream, river, and ocean environments);
     * dry-land environments (desert, grassland, rainforest, and forest environments); and
     * population and community.

Interrelationships in Earth/Space Systems  Power Point Presentation

3.7  The student will investigate and understand the major components of soil, its origin, and importance to plants and
     animals including humans.  Key concepts include
     * soil provides the support and nutrients necessary for plant growth;
     * topsoil is a natural product of subsoil and bedrock;
     * rock, clay, silt, sand, and humus are components of soils;
     * soil is a natural resource and should be conserved.

Earth Patterns, Cycles, and Change

3.8  The student will investigate and understand basic sequences and cycles occurring in nature.  Key concepts include
     * sequences of natural events (day and night, seasonal changes, phases of the moon, and tides); and
     * animal and plant life cycles.
3.9  The student will investigate and understand the water cycle
     and its relationship to life on Earth.  Key concepts include
     * the origin of energy that drives the water cycle;
     * processes involved in the water cycle (evaporation,
        condensation, precipitation); and
     * water supply and water conservation.

Resources

3.10 The student will investigate and understand that natural events and human influences can affect the survival of
     species.  Key concepts include
     * the interdependency of plants and animals;
    * human effects on the quality of air, water, and habitat;
     * the effects of fire, flood, disease, erosion, earthquake,
        and volcanic eruption on organisms; and
     * conservation, resource renewal, habitat management, and
       species monitoring.
3.11 The student will investigate and understand different sources of energy.  Key concepts include
     * the sun's ability to produce light and heat energy;
     * natural forms of energy (sunlight, water, wind);
     * fossil fuels (coal, oil, natural gas) and wood;
     * electricity, nuclear power; and
     * renewable and nonrenewable resources.
