• Characteristics of living things 

     Tell the difference between living and nonliving things based on characteristics common to living things: including growth and development, reproduction, cellular organization, use of energy, exchange of gases, and response to the environment.

    • Life cycles - distinguish between the different life cycles of various organisms, including complete and incomplete metamorphosis and human life cycles. Stimuli and behavior - predict how an organism will change its behavior given an external stimulus.
    • Homeostasis of organisms and feedback - predict how an organism's internal environment will respond given a stimulus.

    Cells

    Review concepts of cell theory, prokaryotic and eukaryotic cells, cell structures, plant and animal cells, photosynthesis, cellular respiration, homeostasis of cells.

    • Cell theory - explain the components of the scientific theory of cells: all organisms are composed of cells, all cells come from pre-existing cells, and cells are the basic unit of life.
    • Prokaryotic and eukaryotic cells - describe the structure and function of the nucleus and distinguish between a prokaryotic and eukaryotic cell.
    • Cell structures - describe the structure and function of cell membranes, cytoplasm, and mitochondria.
    • Plant and animal cells - describe the structure and function of cell walls, vacuoles, and chloroplasts, and distinguish between plant and animal cells.
    • Photosynthesis - explain how light energy is transferred to chemical energy through the process of photosynthesis.
    • Cellular respiration - describe and investigate how aerobic and anaerobic cellular respiration breaks down food to provide energy and releases carbon dioxide.
    • Homeostasis of cells - explain how cells of all organisms undergo similar processes to maintain homeostasis, including extracting energy from food, getting rid of waste, and reproduction.

    Unicellular and Multicellular Organisms

    Reinforce concepts of cells and organisms, unicellular organisms, and multicellular organisms.

    • Cells and organisms -  compare life processes at the organism level with life processes at the cellular level.
    • Unicellular organisms - identify unicellular organisms, including bacteria and protists, by their methods of locomotion, reproduction, ingestion, excretion, and effects on other organisms.
    • Multicellular organisms - compare and contrast unicellular and multicellular organisms

    Classification

    Cover the topic of classification - sections on the concepts of domains and kingdoms,  and classification of life

    Lessons are organized into the following sections:

    • Domains and kingdoms - describe how living things are classified into domains and kingdoms.
    • Classification of life - analyze how organisms can be classified by family, genus, and species

    Organs and Organ Systems

    Review concepts of levels of organization in living things, integumentary system, skeletal and muscular systems, circulatory system, respiratory system, digestive system, excretory system, nervous system, endocrine system, reproductive systems, and disease and the immune system.

    Lessons are organized into the following sections:

    • Levels of organization in living things - review the difference between cells, tissues, organs, and organ systems.
    • Integumentary system -  structure and function of the integumentary system.
    • Skeletal and muscular systems - structure and function of the skeletal and muscular systems.
    • Circulatory system -  structure and function of the circulatory system.
    • Respiratory system - structure and function of the respiratory system.
    • Digestive system -  structure and function of the digestive system.
    • Excretory system - structure and function of the excretory system.
    • Nervous system - structure and function of the nervous system.
    • Endocrine system - structure and function of the endocrine system.
    • Reproductive systems - structure and function of the reproductive system.
    • Disease and the immune system - structure and function of the immune system.

     Plants - cover concepts of plant structures and plant reproduction.

    Lessons are organized into the following sections:

    • Plant structures -  structure and function of leaves, stems, and roots.
    • Plant reproduction

    Genetics

     basics of genetics on the concepts of sexual and asexual reproduction, heredity, genes, and chromosomes, mitosis, meiosis, predicting inheritance, genetic disorders, DNA, and selective breeding.

    Lessons are organized into the following sections:

    • Sexual and asexual reproduction -  compare and contrast asexual and sexual reproduction.
    • Heredity, genes, and chromosomes - explain the role of genes and chromosomes in the process of inheriting a specific trait.
    • Mitosis - describe how cells divide to increase their numbers through the process of mitosis.
    • Meiosis - processes of mitosis and meiosis in relation to growth, repair, reproduction, and heredity.
    • Genetic disorders - tell the difference between genetic disorders due to errors in meiosis and those due to combinations of genes from each parent.
    • DNA - compare and contrast DNA and RNA.
    • Selective breeding
