    1. Cell-the smallest unit that can perform all life processes

     

    1. Stimulus- anything that causes a reaction or change in an organism or any part of an organism.

     

    1. Homeostasis-the maintenance of a constant internal state in a changing environment

     

    1. Asexual reproduction-reproduction that does not involve the union of sex cells an in which one parent produces offspring that are genetically identical to the parent.

     

    1. Sexual reproduction-reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents.

     

    1. Spontaneous Generation-the mistaken idea that living organisms arise from nonliving sources.

     

    1. Classification-process of grouping things based on their similarities.

     

    1. Taxonomy-scientific study of how things are classified.

      1.  Reference Point - the starting point you choose to describe the location or position of an object

      2.  Position - an object's distance in a certain direction from a reference point

      3.  Motion - the process of changing position

      4.  Displacement - the difference between the first position and the final position of an object

      5.  Speed - the measure of the distance an object travels per unit of time

      6.  Constant Speed - the rate of change in position in which the same distance is traveled each second

      7.  Instantaneous Speed - speed at a specific instant in time

      8.  Average Speed - the total distance traveled divided by the total time taken to travel that distance

      9.  Velocity - the speed and direction of a moving object

      10.  Acceleration - a measure of the change in velocity during a period of time

       

     
     
    1.  Quantitative - numerical information (6 feet tall, 120 degrees Celsius, 2 Liters)
     
    2.  Qualitative - information that is descriptive; in the form of adjectives; collected by your senses (hot, furry, the male lions were aggressive, the liquid flows smoothly)
     
    3.  Scientific Inquiry - The process of discovery in science; ways that scientists study the natural world
     
    4.  Hypothesis - a possible explanation for a scientific problem or question you have; educated guess
     
    5.  Manipulated (Independent) Variable - also called independent variable; the one change that is tested in an experiment
     
    6.  Responding (Dependent) Variable - also called the dependent variable; the result that is being measured in an experiment
     
    7.  Control group - One of the groups in the experiment that is left untested.  An experiment needs one control group and several experimental groups.
     
    8.  Controlled Variable - also called controls; the many factors that stay the same throughout the experiment 
     
    9.  Data - information you collect in an experiment; may be qualitative or quantitative
     
    10.  Scientific Law - a statement that explains what will happen every time the same conditions are present.
     
    11.  Scientific Theory - a well-tested explanation
