theory
|
the most logical explanation for things that occur in nature
|
|
law
|
Once a theory has passed many tests and is generally accepted by the scientific community, it becomes a ___.
|
|
geology
|
study of rocks and minerals as well as the origin, history, and structure of the earth.
|
|
meteorology
|
the study of weather, climate, and phenomena in the atmosphere.
|
|
oceanography
|
the study of oceans, including their physical features and life forms.
|
|
astronomy
|
the study of characteristics of objects in space (planets, stars, galaxies, black holes, supernova, nebulae, etc.)
|
|
scientific method
|
a way to solve problems in all branches of science. It is usually, but not always, followed in a specific number of ways.
|
|
variable
|
the condition being tested
|
|
control
|
the ideal conditions for running an experiment, nothing is being tested.
|
|
data
|
information, often in the form of facts or figures obtained from experiments or surveys, used as a basis for making calculations or drawing conclusions
|
|
fair test
|
an experiment that only tests one variable at a time.
|
|
metric system
|
the scientific system of measurement.
|
|
meter
|
unit of length in the metric system
|
|
mass
|
the amount of matter in an object
|
|
volume
|
The amount of space an object takes up
|
|
Liter
|
a unit in the metric system that measures volume of liquids
|
|
cubic centimeter
|
a unit in the metric system that measures volume of regularly shaped solids
|
|
gram
|
a unit in the metric system that measures mass
|
|
weight
|
the measure of attraction between 2 objects due to gravity
|
|
newton
|
a unit of weight that space agencies use; it is the ratio of the gravitational attraction of two objects
|
|
density
|
mass per unit volume; D = M/V
|
|
celsuis
|
measures temperature in the metric system
|
|
dimensional analysis
|
the method for converting one unit to another.
|
|
refracting telescope
|
an optical telescope that uses a series of lenses to focus light
|
|
reflecting telescope
|
an optical telescope that uses a series of mirrors to focus light
|
|
electromagnetic spectrum
|
consists of both visible and invisible light.
|
|
radio telescope
|
collects radio waves which are focused onto an antenna that translates the signal into a picture.
|
|
infrared telescope
|
detects heat energy which is given off by all objects. This type of telescope is usually found in orbit because infrared energy from distant objects has a hard time passing through our atmosphere.
|
|
ultraviolet telescope
|
also usually found in orbit because our atmosphere blocks many UV rays, especially those from objects that are very far away.
|
|
X-ray telescope
|
usually found in orbit around earth. These telescopes have provided information on the life cycles of stars. Top picture is an X-ray image of 5 galaxies making up NGC 4410.
|
|
Hubble Telescope
|
orbits earth and consists of several different types of telescopes
|
|

|
°F = (°C x 1.8) + 32
|
|
(convert degrees fahrenheit to degrees celsius)
|
°C = (°F – 32) x .5555
