• UNIT 1:

    • Life Science
      • The study of living things
    • Scientific Methods
      • A series of steps followed to solve problems
    • Hypothesis
      • An explanation that is based on prior scientific research or observations and that can be tested
    • Controlled Experiment
      • an experiment that tests only one factor at a time by using a comparison of a control group with an experimental group
    • Variable
      • A factor that changes in an experiment in order to test a hypothesis
    • Model
      • A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept
    • Theory
      • An explanation that ties together many hypotheses and observations
    • Law
      • A summary of many experimental results and observations, a law tells how things work
    • Technology
      • The application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs
    • Area
      • A measure of the size of a surface or region
    • Volume
      • A measure of the size of a body or region of a three-dimensional space
    • Mass
      • A measure of the amount of matter in an object
    • Temperature
      • A measure of how hot (or cold) something is

    UNIT 2:

    • Cell
      • The smallest unit that can perform all life processes; cells are covered by a membrane and have DNA and cytoplasm
    • Stimulus
      • Anything that causes a reaction or change in an organism or any part of an organism
    • Homeostasis
      • The maintenance of a constant internal state in a changing environment
    • Sexual Reproduction
      • Reproduction in which the sex cells from two parents unite, producing offspring that share traits from both
    • Asexual Reproduction
      • Reproduction that does not involve the union of sex cells and in which one parent produces offspring identical to itself
    • Heredity
      •  The passing of genetic traits from one parent to another
    • Metabolism
      • The sum of all chemical processes that occur in an organism
    • Producer
      • An organism that can make its own food by using energy from its surroundings
    • Consumer
      • An organism that eats other organisms or organic matter
    • Decomposer
      • An organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients
    • Protein
      • A molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes in the body
    • Carbohydrate
      • A class of energy giving nutrients that includes sugars, starches, and fiber; contains carbon, hydrogen and oxygen
    • Lipid
      • A type of biochemical that does not dissolve in water; fats and steroids are lipids
    • Phospholipid
      • A lipid that contains phosphorus and that is a structural component in cell membranes
    • ATP
      • Adenosine triphosphate, a molecule that acts as the main energy source for cell processes
    • Cell Membrane
      • A phospholipid layer that covers a cell's surface; acts as a barrier between the inside of a cell and the cell's enviroment
    • Organelle
      • One of the small bodies in a cell's cytoplasm that are specialized to perform a specific function
    • Nucleus
      • In a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction
    • Prokaryote
      • An organism that consists of a single cell and no nucleus
    • Eukaryote
      • An organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaebacteria or eubacteria
