__FREEMAN ES SOL 1
Mrs. Freeman's ES SOL Review # 1 Scientific Investigation
| Question | Answer |
|---|---|
| A hypothesis | is a prediction about a problem that can be tested. |
| A variable | is a changeable factor in an experiment. |
| Constants. | are factors that are the same |
| Scientific theories | are systematic sets of concepts that offer explanations for observed patterns in nature. Any valid scientific theory has passed tests designed to invalidate it. |
| Scientific laws. | are generalizations of observational data that describe patterns and relationships |
| Density = | mass/volume |
| The SI Units for Density are : | grams/cm3 or g/mL |
| Volume for irregular objects | is found by water displacement. |
| Water is the | most dense as a liquid. |
| The Density of water = | 1 g/mL |
| Warm (air – water - magma) rises | because it is less dense. |
| As pressure increases | so does density |
| The same substance | has the same density. |
| As mass increases | so does the volume |
| The altitude of Polaris. | equals your Latitude |
| Latitude lines run east to west | but are measured north and south of the Equator. |
| Longitude lines run north to south | but are measures east and west of the Prime Meridian. |
| The closer the Contour Lines | the steeper the slope of the land. |
| Contour lines form V's | and point upstream of rivers |
| Cold (air - water - magma) Sinks. | because it is more dense |
| The Independent Variable | is the variable changed by the experimenter |
| The Dependent Variable | is the final result measured at the end of the experiment |
| The Independent Variable is graphed on the _____ axis | X |
| The Dependent Variable is graphed on the _____ axis | Y |
| A control is used to compare an experiment | to the situation that would occur normally or is not given the experimental conditions |
| contour lines | are used to show the change in elevation on a topographic map |
| Index contours | are the lines that are darkened and have numbers on them to help use read a topographic map |
| topographic maps | are used to show change in elevation on a map |
| Rivers on a topographic map | are shown by a V shape pointing to the source of the river |
| Water runs __________ on all maps | downhill |
| Why is there distortion on a map? | Maps are models of a 3D surface in a 2D format |
| Maps that are of a smaller area have ________ distortion and maps of larger areas have _______ distortion. | less more |
| Contour lines that are close together | indication an area that is steep on a topographic map |
