Volker Steuber Biocomputation Research Group University of Hertfordshire UK vsteuberhertsacuk HodgkinHuxley Model 60 years and one Nobel Prize later The HodgkinHuxley model is phenomenological rather than mechanistic. Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An . Ocean Current. is a large volume of water flowing in a certain direction.. Wind-driven currents are called surface currents.. Anions. Cations. Naming Ions. Naming Ionic Compounds. Writing Ionic Formulas. Identify some Anions and . Cations. Anions. Cations. Metals Lose Electrons . (. Cations. = +). Nonmetals tend to gain electrons (Anions = -). The Earth is Spinning…. Because Earth spins, winds and water appear to be deflected in a curved motion. This is called the Coriolis Effect. Which way do things. not connected to . Earth get deflected . Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . Global winds. Ocean Currents . Local winds. Coriolis Effect. Because the Earth rotates, and consists of a mixture of land and sea, the . Coriolis Effect . exists. The . Coriolis Effect. is the movement of particles (such as air) to the right in the Northern Hemisphere. 6. th. Grade Earth Science. Currents. A current is a large stream of water that flows through the ocean. . Two types of currents. Surface Currents Deep Currents. Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. Chapter 7. An . ion. is an atom that has gained or lost electrons from the valence shell.. Valence electrons. are the electrons contained in the highest occupied energy level. These electrons will mostly determine the chemical properties of the element. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. Focus on equations with a precipitate.. Total Ionic Equations. Write the equation . (synthesis, decomposition, etc. .). check . for reactants and products that are . soluble. or . insoluble. .. We usually assume the reaction is in . Earth/Space. S.W.B.A.T.. Explain how winds and the . Coriolis. effect influence surface currents. Discuss the temperatures of coastal waters. Describe density currents and how they affect Earth. Surface Currents. Highways in the Sea. What forces are responsible for currents?. Wind. : transfers energy through friction on surface; causes currents and waves. Sea level. : steeper slope=greater pressure gradient=drives a larger, faster current.
