Scientific Method 1
result of using one or more senses to gather information
observation
factors in an experiment that do not change
constant
Jupiter, Saturn, Uranus, Neptune
Gas/Frozen Planets
shaped like a ball, with all points on the surface at an equal distance from the center.
sphere
thick middle layer in the solid part of Earth
mantle
dense metallic center of Earth
core
science
use of words to describe what is observed in an experiment
qualitative data
Mercury, Venus, Earth, Mars
terrestrial planets
The solar system has ___ planets...
8
Brittle, rocky outer layer of Earth
crust
landforms with high relief and high elevation
mountains
set of steps you follow to test a hypothesis
experiment
Possible explanation for an observation that can be tested by scientific investigations
hypothesis
Inner planets similar to Earth that have rocky surfaces and cores made of Iron
Earth’s entire solid body.
geosphere
areas with low relief and high elevation
plateau
landforms with low relief and low elevation
plains
Statement of what will happen next in a sequence of events
prediction
An explanation of observations of events that is based on knowledge gained from many observations and investigations
scientific theory
Regular repeating path that one object in space takes around another one
orbit
What is the density equation?
density = mass/volume
topographic features formed by processes that shape Earth's surface
Landforms
describes the height above sea level of a particular feature
elevation
description of how similar or close measurements are to each other
precision
describes a pattern or an event in nature that is always true.
scientific law
a huge collection if gas, dust, billions of stars, and their solar systems held together by gravity.
galaxy
A plant has a density of 3g/cm3 and volume of 10 cm3. What is the mass?
mass = 30 g
term that scientists use to describe differences in elevation
relief
describes the shape of a geographic area
topography
the variable that is changed or manipulated. It is the factor you want to test
independent variable
uses numbers to describe what is observed
quantitative data
the force that every object exerts on all other objects because of their masses.
gravity
A computer has a mass of 10 g and density of 2 g/cm3. what is the volume?
volume = 5 cm3
What are the 4 main layers of Earth?
Inner core, outer core, mantle, crust
What are the 5 Earth systems?
Cryosphere, geosphere, atmosphere, hydrosphere, biosphere
