Haiku on Heavens:
Beautiful clear sky
Many wonders to be found
This world discovered
Developing Ideas about the “Heavens”
First Nations Story of the Sky:
• Thought the night sky was a pattern on a great blanket overhead and holes that were stars
• Believed, the blanket was kept up by a spinning “world pole”
• Bottom of the pole was on a woman underground named Stone Ribs
Tracking Cosmological Events
• Summer and winter solstice were very important for the first nations
• Solstice comes from latin sol meaning sun and stice meaning stop
• In north summer solstice is near June 21 o Marks the longest period of daylight in the year and start of summer …show more content…
The sphere was called the celestial sphere where the stars stayed put.
Heliocentric Model (of planetary motion): In 1530, a polish astronomer Nicholas Copernicus proposed a different model than the geocentric. Heliocentric model is when the sun is the put at the center of the universe and the planets revolve around the sun.
Proposed by: Nicholas Copernicus
Why this belief was proposed:
A little less than 100 years later, a new generation of scientist with the help of the telescope, confirmed Copernicus’s theory. A German mathematician, John Kepler, came up with the next solution to the puzzle to predict planetary motion accurately. His observations led to astronomers realizing that planets orbit the sun in elliptical paths.
Elliptical Orbit: The planets orbit the sun in an oval shape. An orbit is in the
How do we look at the sky?
What technologies were employed to investigate the sky, and space?
Earliest:
Sundials: have been used more than 7000 years to measure the passage of …show more content…
14 century astronomer Levi ben Gurson invented the cross staff to measure the angle between the moon and any given star
Sextant: combination of quadrant, cross-staff and compass direction to allow sailors to position themselves on the ocean surface by looking at star locations/tracts
Compass: tool that locates magnetic north, and can provide direction from north to locate objects
In 16 century the telescope was invented
It revolutionized astronomy
Astronomers could see in night
Telescopes revealed exciting details about earth’s closest planetary
MOST SIGNIFICANT IMPROVEMENT IN TECHNOLOGY: Telescope

Types of Telescopes:
Optical Telescopes
Refracting Telescope
- Use two lenses to collect ligh, and then focus it to improve our vision of distant objects
- Gather and focus straight
