Astronomy Project A Lunar Eclipse is an eclipse in which the full moon passes partially or wholly through the umbra of the earth's shadow (Merriam-Webster, 2012). When this happens, the moon appears darker as it passes into the earth's shadow. One thing that I found interesting is that there are different types of eclipses. When I first read more information on the lunar eclipse I was confused about what those differences are. I found out that during the five thousand year period from 2000 BCE

Soil and Water conservation H. H. Bennett once said, “Soil conservation is probably the youngest of all the agricultural sciences.” Its newness doesn’t make it any less important, especially in small towns where people rely heavily on soil and water conservation to grow crops to feed their families and people around the world. In 2000, slightly more than one-half of the nation’s population lived in jurisdictions cities, towns, boroughs, villages and townships with fewer than 25,000 people

OBJECTIVE The goal of this experiment was to demonstrate the acceleration of a free-falling object which is imposed by gravity. PROCEDURE We began this experiment by taking a long strip of paper approximately 3 centimeters in width and 1 meter in length and properly inserting it into the vibrating apparatus. Holding the paper in place, we then adjusted the machine’s setting to 40 hertz per second. By doing so, the machine vibrates – resulting in a marking on the paper – 40 times per

a Jewish family as the middle child of 3. Bohr’s mother was from a rich Jewish banking family, and father was from a renowned physiologist, so Bohr was situated for success. Bohr attended Copenhagen University to earn his masters and doctorate in physics by 1911. Bohr traveled to Cambridge to work under scientist J.J. Thomson. In 1912, Bohr’s research theorized that atoms give off electromagnetic radiation as electrons jump to different orbit levels. Bohr’s idea deviated from Rutherford’s model, which

Absolut og relativ tilvækst Formålet med vedlagte GeoGebra-fil er at undersøge sammenhængene mellem absolut og relativ tilvækst af den uafhængige variabel og absolut og relativ funktionstilvækst, dvs. vækst af den afhængige variabel, for lineære funktioner, eksponentielle funktioner og potensfunktioner. Aktiviteten er tænkt som et visuelt og interaktivt supplement til gennemgangen af følgende sætninger, som man gerne finder i matematikbøger til 1.g i gymnasiet (her citeret næsten ordret fra Gyldendals
