Lesson 1
A small piece of rock and metal that travels in space around the sun that looks like a "shooting star"
What is meteoroid
Stars that are in groups when viewed from Earth
What is constellation
This can gather and focus light which bounces off a shiny surface
What is reflection
Ocean tides rise and fall because of this
What is gravity
This type of lens brings light rays together
What is convex lens
This is made of ice, dust, and gases that travels through space and orbits the sun
What is comet
A group of billions of stars, dust, and gases which are held together by gravity
What is galaxy
This separates light into a pattern of lines of different colors to analyze what elements a star contains
What is spectroscope
This is between Mars and Jupiter
What is the asteroid belt
Astronomers use this type of measurement for the solar system
What is Astronomical Units (AUs)
A bright streak of light that passes through Earth's atmosphere
What is meteor
The distance light travels in one year which is used to measure distances in space
What is a light year
A way to gather and focus light by bending light as it passes from one material to another
What is refraction
In this model, it is believed that the sun and other objects in the sky revolved around the Earth
What is Ptolemy's model
This type of lens causes light rays to spread apart
What is concave lens
This lands on Earth after passing through the atmosphere
What is meteorite
A star's brightness depends on these 3 qualities
What is/are size, temperature, and distance
This person made a reflecting telescope
What/who is Isaac Newton
In this model, the sun was in the center of the solar system with the planets revolving in circles around it
What is Copernicus's Model
238,390 in expanded form
What is
200,000 + 30,000 + 8,000 + 300 + 90
A rocky object that revolves around the sun
What is asteroid
Stars are grouped up by 3 types of properties
What is/are brightness, color, and size
This person made a refracting telescope.
What/who is Galileo
In this model, the sun is in the center with the planets revolving in elliptical paths
What is the Modern Solar System Model
The number of
300,000 + 80,000 + 4,000 + 500
What is 384, 500 (three hundred eighty-four thousand, five hundred)
