Nature of Science
All humans are born with this.
What is curiosity?
All graphs must have a minimum of two of these. They are designated by the letters x and y.
What are axes?
All galaxies are made up of gas, dust, stars and this.
What are their solar systems?
When ancient Greeks figured out the diameter of Earth, it led to the development of this important tool of measurement.
What is the Astronomical unit?
This is a title that describes the data on an axis.
What is a title or axis title?
These are educated guesses based on observations.
What are inferences?
This functions that same on a graph as it does on a map.
What is a legend?
This type of galaxy has a fuzzy appearance and is shaped like an oval.
What is an elliptical galaxy?
This is the name given for the displacement of an object as seen by our left eye and our right eye.
What is parallax?
This is defined as the measure of brightness.
What is luminosity?
When we first learn how to talk as toddlers we begin to ask questions to gain knowlede and information. This term describes this action.
What is inquiry?
This variable is the variable that is changed and is graphed on the "x" axis.
What is the INDEPENDENT VARIABLE?
Each spiral galaxy is theorized to have one of these in the center.
What is a super massive black hole?
When parallax could no longer be used to help determine distances in space, early astronomers used what they new about the astronomical unit and sunlight to develop this measurement tool.
What is the light year?
This is the general direction that data moves on a graph.
What is trend?
Data that is collected in the form of numbers, this includes measurements, number of parts, measures of time, etc.
What is quantitative?
If I need to graph the hours of sunlight in an experiment where the only thing changed is the number of hours plants were left in the sun, I would put it on this axis.
What is the "x" axis?
This type of galaxy has no truly defined shape, nor does is fit into the Hubble classification scheme.
What is an irregular galaxy?
When the light year did not provide a measurement large enough for very distant objects, this measurement was developed.
What is the parsec?
This is defined as the type of measurement used on each axis.
What are units?
This is defined as; to carry out research or study through observation.
What is investigate?
We learned about three types of graphs. This type of graph is best used for a change over time or distance.
What is a line graph?
This is the name of our nearest galactic neighbor.
What is Andromeda?
If we could travel from the Milky Way to Andromeda, this is the measurement of distance that we would likely use.
What is a parsec?
This is defined as to discover or reveal (something) through detailed examination.
What is analyze?
