Test 3
Isolines
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.
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:

Maps
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.
Latitude
Distance North or South of the Equator (0 degrees Latitude)
Like rungs on a ladder
Also known as parallels
Longitude
Distance East or West of the Prime Meridian(0 degrees Longitude)
Also known as meridians
Lines of Latitude and Longitude
Test 1
Metric Measurements
length or distance in metrics-Meters(m)
Measuring mass-Grams(g)
Measuring Volume-Liters(l)
Conversions
1m= 100cm =1000mm= .001km
1g= 1000mg= .001kg
1l=1000ml= .001kl
Scientific Method-9/24
Define the Problem
Form a Hypothesis
Create a Procedure
Experiment
Analyze Data
Draw Conclusions
Quantitative vs Qualitative data-9/26
Quantitative-measure ie 10cm
Qualitative-descriptive ie cloudy
Variables-9/27
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.
