Definitons
Describes all kinds of light, including those the human eye cannot see
What is electromagnetic spectrum?
Uses lenses to gather and focus light by bending light
What is a refracting telescope?
One of the first instruments that was first used and developed to measure the altitude of the Sun, Moon, planets, or stars
What is an astrolabe?
Study of the universe
What is Astronomy?
What we keep the same for our experiment to be fair
What is control variable?
The 0° and 90° components on an astrolabe
What is horizon and zenith?
Proposed by Claudius Ptolemy
What is the geocentric theory?
The moon orbiting the Earth
What is a Natural Satellite?
Time required for Earth to rotate once on its axis
What is a day?
What we change/manipulate
What is dependent variable?
Measurement of distances outside the solar system
What is a lightyear?
What is the James Webb Telescope?
Uses a curved mirror to gather and focus light
What is a reflecting telescope?
The time required for the moon to orbit once around the Earth
What is a month?
What we measure
What is dependent variable?
Brightness of a star based on location of the observer
What is apparent magnitude?
Found moons of Pluto and is the length of a large school bus
What is the Hubble Telescope?
Measured by an astrolabe
What is altitude?
The time required for Earth to orbit once around the sun
What is a year?
Tomato plants were grown at various temperatures. The number of tomatoes that grew on each plant was counted. Each plant started out from seeds and the same amount of soil, water, and sunlight was used. The results were:
4˚C-4 tomatoes,
8˚C- 10 tomatoes,
16˚C- 18 tomatoes,
24˚C-16 tomatoes
Identify the independent, dependent, and control variables.
What are temperature (independent), number of tomatoes (dependent), and same amount of soil, water, & sunlight (controls)?
A measurement of the brightness of a star based on the amount of energy it emits
What is absolute magnitude?
Proposed by Nicolaus Copernicus
What is the heliocentric theory?
What is a Man-made Satellite?
Measurement of distances within the solar system
What is astronomical unit?
Buzz wanted to test how high he could jump on Earth vs. the Moon. He performed the test on Earth in the same space gear before going to the moon.
Average height on Earth: .6 meters
Average height on the Moon: 3.6 meters
Identify the independent, dependent, and controls variables.
What are location (independent), height in meters (dependent), and same space gear (controls)?
