Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

one another. These pieces slowly assumed their present positions as the continents. PLATE TECTONIC THEORY Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth’s surface relative to each other‚ like slabs of ice on a lake. There are seven or eight major plates and many minor plates. Where plates meet‚ their relative motion determines the type of boundary: convergent‚ divergent‚ or transform

Constructive Plate Margin * This is where two plates move apart be it any combination of crust type either sial or sima. At a sima and sima divergence such as the Eurasian Plate and the North American Plate‚ both crusts diverge leaving magma to rise up. This with aid from the cool ocean water solidifies and creates gentle sloping volcanos with basic basaltic lava with low viscosity. The type of volcanoes found at these margins are shield and fissure volcanoes. At this specific plate margin‚ at

Plate Tectonics Press Release GLG.101 August 16‚ 2013 Plate Tectonics Press Release Natural destroys are a part of the nature of the world. There are many different kinds of natural destroys hurricanes‚ tornados‚ tropical storms‚ and earthquakes. The great state of California is no stranger to its part of natural destroyers. Many cities in the state have had its share having earthquakes. Earthquakes are produced by abrupt motion along a fault when friction that resists such motion is overcome

the topographical features at divergent and convergent plate margins. Subject: Earth Environments 1: Geomorphology and Soils Course Code: GEOG 1231 Divergent and convergent plate margins are both studied in plate tectonics; which is the study of the plates that makeup the lithosphere‚ their movements and how these movements has influenced changes in the surface’s topography (Strahler‚ 2011‚ 389). The driving force that causes these plate movements is the gradual movement of the semi-molten rock

EXPERIMENT: Pressure drop over a bubble cap plate. AIM : This experiment is conducted in an experimental test ring in which the effect of the variation in vapor and liquid flow rates on the pressure drop across bubble cap plates is simulated using air and water to represent the vapor and liquid respectively. THEORY: In a pilot tube the relation between the gas velocity and pressure drop is Where‚ is the differential pressure as expressed in the head of the fluid flowing. Where‚ ’=level

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms

Procedure Have three petri dishes prepared with blood agar‚ and three test tubes with 100 milliliters of milk. Label three test tubes‚ “A‚” “B‚” and “C.” With a toothpick‚ add a small amount of the E. coli specimen to tube “B"; shake the test tube to mix throughly. For test tube “C‚” add the same amount
