With the help of scanning electron microscopes, we can see fuzzy images of atoms. Electron microscopes enable us to see an image with a wavelength as small as 10-9 m. Light microscopes enable us to view parts of a cell as small as 10-6 m. That most of the mass of an atom is concentrated in a small region in its center, now called the nucleus. Rutherford systematically investigated the results Geiger and Marsden obtained with alpha particles Rutherford concluded However, some particles were deflected and others recoiled back toward the source. They observed that most of the alpha particles went directly through the foil. It is also useful in the mathematics classroom by plotting the angles of incidence and reflectionДЇrom 1911 to 1913, British physicists Geiger and Marsden, working in the laboratory of Ernest Rutherford, conducted experiments with beams of positively charged, alpha particles to penetrate gold, silver, and copper atoms.

It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers. It is based upon the Rutherford Gold Foil Experiment where scientists discovered that the structure of the atom includes the nucleus in the center surrounded by electrons in empty space.

Students will try to determine the shape of an unknown object by using the scientific thought process of creating a hypothesis, then testing it through inference.

Students should avoid stepping on marbles.

Students should use care when handling marbles.

(Since the particles are too small to be seen, it was necessary to deduce their sizes by other means in both of these instances.) This experiment is best used by students working in pairs.Д¤0-60 minutes вЂ“ To make the Rutherford boardsД¤0-60 minutes вЂ“ To prepare for the classroom By extension, this device is a useful analogy to RutherfordвЂ™s alpha scattering experiments and to atomic particle detection utilizing accelerators. In 2016, the Anthropocene Working Group agreed that the Anthropocene is different from the Holocene, and began in the year 1950 when the Great Acceleration, a dramatic increase in human activity affecting the planet, took off.Description: With the Mini Rutherford Activity, students deduce shapes and sizes of unseen objects by tracking the movements of objects they can see, in relation to the unseen object. The resulting radioactive particles were detected in soil samples globally. This is when humans tested the first atomic bomb, and then dropped atomic bombs on Hiroshima and Nagasaki, Japan. Others think that the beginning of the Anthropocene should be 1945. A popular theory is that it began at the start of the Industrial Revolution of the 1800s, when human activity had a great impact on carbon and methane in EarthвЂ™s atmosphere. To those scientists who do think the Anthropocene describes a new geological time period, the next question is, when did it begin, which also has been widely debated. The primary question that the IUGS needs to answer before declaring the Anthropocene an epoch is if humans have changed the Earth system to the point that it is reflected in the rock strata. Scientists still debate whether the Anthropocene is different from the Holocene, and the term has not been formally adopted by the International Union of Geological Sciences (IUGS), the international organization that names and defines epochs. The word Anthropocene is derived from the Greek words anthropo, for вЂњman,вЂќ and cene for вЂњnew,вЂќ coined and made popular by biologist Eugene Stormer and chemist Paul Crutzen in 2000. However, the Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in EarthвЂ™s history when human activity started to have a significant impact on the planetвЂ™s climate and ecosystems. Officially, the current epoch is called the Holocene, which began 11,700 years ago after the last major ice age. The study of this correlation is called stratigraphy. From examining these fossils, scientists know that certain organisms are characteristic of certain parts of the geologic record. These units are classified based on EarthвЂ™s rock layers, or strata, and the fossils found within them. These divisions, in descending length of time, are called eons, eras, periods, epochs, and ages.

EarthвЂ™s history is divided into a hierarchical series of smaller chunks of time, referred to as the geologic time scale.
