    Test 3


    Isoline-a line connecting points of equal value

    Examples of Isolines:

    Isotherms-lines of equal temperature

    Isobar-lines of equal barometric(air) pressure

    Contour lines-lines of equal elevation

    Index contour-usually a darker contour line with an elevation listed

    V-shaped contour-usually indicate a stream of river


    Isolines are generally gentle curving lines.

    Isolines are closed even though they map might not show the full line.

    Isolines never cross.

    Isolines are usually parallel.

    Contour lines



    Time Zones

    24 Time Zones around the globe based off of the Prime Meridian

    International Date Line is 180 Degrees opposite the Prime Meridian

    US Time Zones:

    Test 2


    Purpose of a map

    Different maps have different purposes.  In general they are used to compare information.  ie. streets in relation to other streets;  population

    Map key or map legend

    Helps identify features on a map.  It typically has a symbols and tells you what it means ie. A picture of a picnic table may be a campsite

    Map Scale

    Shows the relationship between distances on the map and corresponding distances on the ground.

    Compass Rose

    Gives directions of North, South, West and East on the map.

    Magnetic Field

    Magnets have a North and a South Pole.  There is an invisible magnetic field created.

    Distance North or South of the Equator (0 degrees Latitude)

    Like rungs on a ladder

    Also known as parallels

    Image of lines of Latitude


    Distance East or West of the Prime Meridian(0 degrees Longitude)

    Also known as meridians

    Image of lines of Longitude

    Lines of Latitude and Longitude

    Image of both Latitude and Longitude Lines



    Test 1

    Metric Measurements

    length or distance in metrics-Meters(m)

    Measuring mass-Grams(g)

    Measuring Volume-Liters(l)


    1m= 100cm =1000mm= .001km

    1g= 1000mg= .001kg

    1l=1000ml= .001kl


    Scientific Method-9/24

    Define the Problem

    Form a Hypothesis

    Create a Procedure


    Analyze Data

    Draw Conclusions


    Quantitative vs Qualitative data-9/26

    Quantitative-measure  ie 10cm

    Qualitative-descriptive ie cloudy



    Independent Variable-The variable that you change  ie color of light

    Dependent Variable-The variable thata you measure ie height of the plant

    Controlled items-Things that are kept the same between the experimental group and the control group  ie temperature, amount of water, amount of light, type of container, size of container


    Observation vs Inference

    Observation-Something that you can sense.  ie I see the ball rolling.

    Inference-An explanation of something observed.  ie The ball is rolling because it was pushed.
