What comes first in the scientific method?

State the problem

What comes second in the scientific method?

Form a hypothesis

What comes third in the scientific method?

Perform an experiment

What comes fourth in the scientific method?

Collect and analyze data

What comes fifth in the scientific method?

Draw a conclusion

Observations are made using our five

senses

Variable

A factor that has changed the experiment

Independent Variable

Factor that is manipulated by researcher

Dependent Variable

Factor that can change if independent variable is changed.

Constant

Factors that don't change during the experiment

Control

Standard for comparison in an experiment

The independent variable is on the

X axis of a graph

The dependent variable is on the

Y axis of a graph

Scientific Theory

Explanation based on many observations during repeated experiments

Scientific Law

Basic fact that describes the behavior of a natural phenomenon for which no exceptions have been found

Density is a

physical property of matter

Density Formula:

Mass ÷ volume

Water's density is 1.00 g/cm meaning anything of higher density in it would

sink

Water's density is 1.00 g/cm meaning anything of lower density would

float

The Equator is an imaginary line that circles Earth exactly

halfway between the North and South poles

The Prime Meridian is a reference point for east/west grid lines that runs through

Greenwich, England, from the North Pole to the South Pole

The International Date Line is a line at the

180° meridian

Longitude is lines that run north and south and

determine locations east or west of the Prime Meridian

Lines that run parallel to the Equator and

determine North and south locations

What country does the International Dateline pass through

Russia

Which island nation does the prime meridian pass through?

The United Kingdom

Name a country at: 45°N, 120°

China

Name a country at: 30°S, 150°E

Australia

Name a country at: 15°S, 45°W

Brazil

Name a country at: 60°N, 15°E

Sweden

Name a country at: 60°N, 150°W

The United States

How many time zones in the world?

24

How many time zones are there in the continental USA (lower 48 only)?

4

If it is 3:30 p.m. in Virginia, what time is it in Colorado

1:30 pm

If it is 1:00pm in Nevada, what time is it in Texas

4 pm

If it is 11:00 a.m. in New York, what time is it in California

8:00 am

Topographic maps show

surface features of the earth

Contour lines connects

point of equal elevation

Topographic maps can never

cross

The contour interval is the difference in elevation between

two side-by- side contour lines

Indez contours are marked by

numbers and are darker

The depression contour is lines at right angles to the

contour lines towards

Contour forms v's that point

upstream

Contours are widely spaced on

gentle slopes

Contours are close on

steep slopes

Contours are evenly spaced on

uniform slop

Hills normally have a circle at the highest point, showing

the elevation.

Water is represented by the color

blue on a topographic map

Man made buildings is represented by

black on a topographic map

Vegetation is represented by

The color green on a topographic map

Urban areas are represented by the color

Purple on the topographic map
