Our understanding of the universe has changed a lot over time!
Ptolemy
He improved on Aristotle's theory which was that the earth was the center of the universe also known as geocentric.
Nicolaus Copernicus
Copernicus had a theory that the sun was the center of our solar system. This is also known as heliocentric.
Tycho Brahe
His work supported the idea that the Earth orbited the sun.
Brahe hired Kepler, another astronomer to work with him.
How has our understanding of the universe changed over time?
Aristotle
Johannes Kepler
Galileo
Isaac Newton
Edmund Halley
Edwin Hubble
By Isamilla & Nelleke
The Hubble space telescope was named after Edwin Hubble.
He had three laws of motion.
He hypothosized that the nebulae were their own galaxies.
<span>He imagined the earth at the </span>
center of the universe with the sun, the moon, the stars and the planets orbiting it in perfect circles.
Newton put Kepler and Galileo's ideas together and discovered that the reason that things fall on the ground is the same reason that planets orbit around the sun.
He made a telescope that could magnify
up to 30 times.
<span>He discovered that Copernicus' theory </span>
was true. "We're not the center of the universe."
He found out that the planets orbit the
sun in ellipses (oval shapes).
He explained how the tides were made by the moon.
He figured out that the speed of the planets depend on the sun.
Halley discovered a comet. It was discovered in 1705. It will come around again in 2061
The comet Halley comes every 75 - 76 years

C. Natural Rights
John Locke had the idea of natural rights, which he stated were life, liberty, and property. The founding fathers changed property to the pursuit of happiness

Both notably believe in heaven and hell, such as Christianity.
never consume moldy bread.Store bread properly to avoid these potentially harmful bacteria.
Penicillium
:Penicillin is well known for being one of the most widely prescribed antibiotics in the world, but the fungus used to produce it, penicillium, is also a common bacterium that grows on bread. According to cmsynergy.com, this bacterium prefers colder environments, such as that found in your refrigerator, and will grow on fruit or bread. It will not grow, however, if the relative humidity in the air is less than 60 percent. Penicillium bacteria form colonies that appear as fuzzy blue-green or gray patches on the bread surface. Neurospora Crassa
:This bacterium species thrives on bread and produces spores on a 24-hour cycle. According to the National Institute of General Medical Sciences, neurospora crassa, "is simple to grow and has features that make it very suitable for answering questions about how species arise and adapt, as well as how cells and tissues change their shape in different environments." Neurospora crassa is red and produces tiny filaments along the surface of bread. Rhizopus Stolonifer
:This common, fast-growing bacterium is a member of the phylum omycota and produces black mold. Rhizopus stolonifer is highly toxic and can destroy bread quickly by consuming nutrients found in the bread. This bacterium grows most rapidly at temperatures between 59 and 86 degrees F. Rhizopus stolonifer spores are generally abundant in the atmosphere, and the bacterium will grow very quickly on bread stored in a relatively humid environment.
Aspergillus
:This common bacterium grows on cheese, decayed fruit and bread. It begins its life green and later turns to shades of reddish-yellow, yellow or reddish-brown. Ideal growing temperature range for aspergillus is between 71.6 to 86 degrees F. This common bacterium grows quickly on bread kept in a moist atmosphere. Most aspergillus species are toxic to humans but some are common ingredients in pharmaceutical drugs.
