4-5 SCIENCE 2015-2016 Science Units The fourth- and fifth-grade social studies theme of explorers and colonial America naturally lends itself to an in depth study of oceans and marine life. The year’s themes include: SALTWATER ECOLOGY THE HUMAN BODY ELECTRONICS AND ROBOTICS The children begin the year by studying plants and animals of the Long Island Sound through several field trips to Cove Island Park, where the students become immersed in the various habitats it provides. They work with…

Carbonyl compounds are the compounds the contain C=O group which is called carbonyl group (double bond oxygen to a carbon). There are many types of carbonyl compounds such as aldehydes, ketones, carboxylic acids, esters, amides etc. Aldehydes and ketones are the oxidation products of alcohols. Depending on the alcohol’s structure, the product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two…

(Somasegaran and Hoben, 2012). According to the observations made during the experiment, roots in treatments with fertilizer (i.e. fertilizer only and Rhizobia +fertilizer) were brown in colour. According to Silva and Uchida (2000), fertilizer reduces nitrates in soil causing a brown colour in roots. Roots had the highest increase in biomass under untreated, this is because when soil nutrients are high a plant spend much energy in building roots to forage in the soil for new nutrient sources…

Revenge is a sickness that plagues the mind and ends lives. In the short story “The Cask of Amontillado,” by Edgar Allan Poe, revenge is taken to the point of murder, simply for the act of insulting an individual to the breaking point. The breaking point was the night of a carnival, where Montresor exacted his revenge by leading Fortunato into the family catacombs, with intent of ending his life. While society would feel that killing is an extreme measure for the act of teasing, there is a…

America. This disease is less common in Northern and Western Africa, South Central Asia, and North America.”. One of the big factors in increased stomach cancer in these areas is due to diet. These people eat foods that are high in salt, nitrites and nitrates. They eat a lot of smoked and salted meats. “There is considerable evidence that occupations in coal and tin mining, metal processing, particularly steel and iron, and rubber manufacturing industries lead to an increased risk of stomach…

Timothy McVeigh was” born on April 23, 1968 in Lockport, New York and grew up nearby in the working-class town of Pendleton” (McVeigh, 2017).Timothy parents divorced, and he went to live with his’s father, where he started to take interest in guns.

usually affected by many factors such as, physico-chemical form of radionuclide, plant species, internal translocation mechanisms within the plant, soil characteristics (pH value), isotopic-binding mechanism of soil, fertilizers (potassium or calcium nitrates, phosphate, organic), chelating agents (organic compounds), distribution of radionuclides in soil and environmental conditions [Martinez-Aguirre & Perianez, 1998; Foth,1978; Abdulaziz Alharbi & A. El-Taher,…

unknown bacterium by various methods. Most stains used in microbiology are differential stain, which use more than one dye so that different cells, chemicals, or structures such as Gram staining, TTC reduction, Oxygen requirement test, Catalase test, Nitrate test, Motility, Triple Sugar test, Carbohydrate Fermentation test, and the IMViC test. Especially, the Gram stain differentiates between two large groups of microorganisms. Plan 03-05-16 The Unknown I.D. Project determines…

a light proof box with a small hole in one side. The light from the scene passes throught this single point projects an invertied image on the other side of the box. Shortly after they created the pinhole camera Albertus Magnus discovered silver nitrate, and George Fabricius discovered silver chloride.…
