In this early history of the atom worksheet, high schoolers answer 4 questions about Thomson's Plum Pudding model of the atom and Rutherford's experiment that led to the understanding of some of the structures of the atom.
For centuries the Hanford area bordering the Columbia River was home to several tribes of Native Americans. Remnants, artifacts and burial sites associated with historical Native American activity are found throughout the Site and are protected by law. The mid-1800s brought pioneers and settlers to the mid-Columbia region. The small towns of White Bluffs and Hanford sprang up to support the farms and ranches of early residents. When the U.S. Department of War decided to locate portions of the Manhattan Project in this part of Washington, it also decided that work to develop atomic weapons had to be done in secret. Subsequently, in early 1943, all of the residents of White Bluffs and Hanford were told to evacuate their homes and abandon their farms, and were given just 30 days and a small amount of money to do so.
Early History Of The Atom Homework Answers
Chemists also now know that elements are made of atoms. Some early Greek philosophers had suggested that matter was made of atoms, but not until the beginning of the 19th century did physicists and chemists begin to collect the evidence needed to prove the theory and to understand the nature of atoms.
The broad divisions such as inorganic, organic, physical, and analytical chemistry emerged early in the history of the subject. Fields such as polymer and environmental chemistry developed during the 20th century, and new ones continue to appear. Major fields of specialization include those below.
Some scientists distinguish between the African (Homo ergaster) and Asian (Homo erectus sensu stricto) fossils of this taxon, while others lump them together as Homo erectus sensu lato. In either case, there is general agreement that it descended from an earlier species of Homo (e.g., Homo habilis) and represents one of the widest dispersals of early humans in our evolutionary history. It is likely that distinct populations of Homo erectus sensu lato led to the emergence of later hominin species, such as Homo heidelbergensis, and ultimately to our own species, Homo sapiens.
Of highest importance is what is revealed in the text ofScripture about the order of events. Genesis 1 contradictsthe evolutionary history of the universe and life in it atnearly every step. [See tables on page 52 and 77.] The Bibleteaches that the earth was covered with water on Day Oneand at the time of the Flood while the evolutionary historydenies that the earth was ever covered with water. 2ff7e9595c
